MISSION-IV
Palaeontological Studies: A search of fossils and preparation of geological map on 1: 50,000
scale was carried out along Shillong-Sohra, Shillong-Mawsynram and Shillong-Dawki in East
Khasi Hills district of Meghalaya. A dozen of oval to rounded egg fossil like samples were
collected in and around Dawki area, East Khasi Hills District, Meghalaya.
Geotechnical Investigations: Geotechnical Evaluation of Water Resource Development Projects
in Arunachal Pradesh was done which include Construction stage geotechnical investigation of
the Kameng H E Project: Package-I (Bichom Dam Complex), Package-II (Tenga Dam Group),
Package-III (Kimi Power House Complex),West Kameng District, Geotechnical Investigation of
Noa Dehing Multipurpose Project, Changlang District, and Geotechnical Investigation for Pare
H.E. Project, Papumpare District, Arunachal Pradesh were also attended. Geotechnical
Evaluation- Pre-Construction Stage of Water Resource development projects in Mawblei Hydro
Electric Project, West Khasi Hills District, Upper Khri Hydro Electric Project, West Khasi Hills
District, New Umtru Hydro Electric Project, Ribhoi District, Meghalaya were also completed.
Other geotechnical investigations carried out in Turial Hydroelectric Project, Kolasib District,
Mizoram pertaining to Water Resource Development Projects, Mizoram.
Medical Geology: Systematic spot analysis of groundwater and surface water by Merck Arsenic
Field kit were carried out in the field in Toposheet 83 B/12 & B/16 to study of arsenic
contamination in water and soil in parts of nagaon and marigaon districts, Assam. The arsenic
values in groundwater varies from nil to 100 ppb where as that of surface water varies from nil to
5 ppb. The high arsenic values occurring as zones were transferred over the geological map shows
iii
that most of the high values occur within the Newer alluvium sediments of Barpeta and Hauli
Formations. Older alluvium sediments are devoid of arsenic contamination thus having fresh
water.
Landslide Hazard Zonation:
Landslide Hazard Zonation Project (LHZP) was formed during 1995 to exclusively cater to the
needs of landslide studies in NER by GSI. Subsequently GSI was declared nodal agency for
landslides by Govt. of India in 2004. GSI has undertaken studies related to landslide at specific
request from State Governments and other organizations. The information has been often used by
Government and other organizations for better planning of their infrastructures, developmental
activities and disaster preparedness.
The problem of landslide hazard is multiplied in recent times due to increased developmental
activities like construction of road, building and various infrastructures. GSI has covered major
part of urban agglomerations, road corridors of the vulnerable hilly terrain in NE India through
macro scale landslide susceptibility mapping. GSI undertakes site specific landslide investigation
for containing the distressing in the hill slopes, comprehensive understanding of the processes, and
formulation of both short and long term mitigation measures. GSI also attempted monitoring of
few conspicuous slides in Sikkim and Meghalaya. GSI, NER regularly updates the landslide
database of the entire NE regions through landslide inventory work. After became a declared
nodal agency for understanding the coordinating landslide investigation and formulation for
mitigation measures. GSI’s activity for Landslide Hazard Risk Mitigation in region includes Pre-
Disaster Study, Landslide Zonation Mapping, Landslide Inventory Work, Detailed Site Specific
Study of landslide for identifying causative factor and most suitable remedial measures, Landslide
monitoring/real time monitoring by instrumentation for development of an early warning system.
During FS 2013-14, Landslide Hazard Zonation studies at macro scale in Anjaw District,
Arunachal
Pradesh and along Rangpo-Singtam-Dikchu-Chungthang road corridor, Sikkim were taken up
besides detailed study of the 13th mile landslide in East District, Sikkim and Site specific study of
proposed Pakyong Airport area, Sikkim.
Updation of existing landslide inventory of NER for FS 2013-14 is as follows:
Assam: 1 Earth-Soil slide & 1 Rock fall.
Arunachal: 7 cut-slope failures, 28 Rock slides, 4 Complex slides, 15 Debris slides.
Meghalaya: 1 rock fissure-ground crack.
Mizoram: 1 Complex slide & 1 Debris slide.
Nagaland: 1 Slope failure, 1 Rock fall, 1 Complex slide, 1 Earth slide, 7 Debris slides & 1
rock slide.
Sikkim: 1 mudslide & 1 debris flow.
Earthquake Studies: Study of Seismic and Landslide Hazard Assessment of Aizawl town,
Mizoram & Kohima City, Nagaland were carried out during FS 2013-14.
Aizawl town, Mizoram: An area of about 50 sq. km was covered by geological mapping and
landslide hazard assessment on 1:25,000 scale in the Aizawl master plan area. Synthesis of
seismicity data within 300 km radius in and around Aizwal area, involving conversion of Ms and
Mb earthquake magnitudes to Mw for assessing the recurrence period and to determine PGA of
the area was undertaken. It appears that the slope instability can be attributed to the inherent rock
mass condition, anthropogenic interference (unscientific slope cutting / static loading due to
constructional activities), unguided drainage, etc. Besides, ground water information based on the
available hand pump locations were recorded and are being analysed with other collateral
subsurface information collected from different Government agencies. The collected field data are
being processed for the preparation of relevant thematic maps for analysis and interpretation
regarding the Seismic Hazard Assessment of the area.
Kohima City, Nagaland: An area of 300 km radius around Kohima city was taken up to carried
out to analyse past seismicity data and delineation of potential seismic source area. The
Morphotectonic and lineament map covering 50 sq. km area was prepared using LISS-III and
iv
SRTM data of Kohima area. Surface Geological Mapping on 1:25,000 scale covering 50 sq. km
was undertaken. Facet wise data collection of about 50 sq. km in the southern part of the study
area was undertaken for landslide hazard zonation. Besides, study of groundwater information
along with borehole litho log collected from the Directorate of Geology and mining, Govt. of
Nagaland was also carried out. Presently the work is under progress and will be continued during
FS 2014-15, the second year of the study.
Gangtok, Sikkim: Seismic Hazard Assessment of Gangtok , Sikkim was carried out by Site
response study by three component digital seismograph (Kinemetrics make SS-1) using H/V
method developed by Nakamura (1989) to eliminate the source effects in the spectra of the micro
tremor signal.

REGIONAL BRIEFING BOOK OF GEOLOGICAL SURVEY OF INDIA
NORTH EASTERN REGION
1. INTRODUCTION
The North Eastern Region with an area of 262,093 sq km (7.92% of Indian Territory) represents varied
geomorphological & geological set up, which is ranging from Precambrian to recent age. It is manifested by
spectacular Himalayan mountain belt in the north, the vast Brahmaputra plain in the central portion, Shillong
Massif plateau in the south and Indo-Myanmar range in the East.
GEOLOGY & MINERAL RESOURCES
A summarised description of geology & mineral recourses of different states of NER is given below:
Arunchal Pradesh: Arunachal Pradesh, borders Bhutan, China and Myanmar, with the Naga Hills to the
south-east. The northern and north-western parts of Arunachal Pradesh comprise mainly ancient metamorphic
rocks, which are called Sela Group towards west and Lohit Granodiorite toward east. The Siang Valley
exposes an extensive sequence of metamorphosed Mesozoic rocks with intercalated volcanic flows. A narrow
strip of Gondwana sandstones and shales with discontinuous coal occurrences, usually crop out along the
southern flank of the metamorphics. The southern foot hills of the Himalayan belt are composed of the
younger Siwalik / Assam Tertiary sedimentaries - silty sandstone, clay and sandstone deposited during the last
stage of mountain-building. Massive and vesicular basaltic and andesitc rocks of Abor volcanics associated
with Miri Quartzite occur in the western flank of Subansisri valley, Igo valley, Basar-Along areas and in Siang
valley areas in Arunachal Pradesh. The easternmost part of the state, namely the Changland and Tirap,
represent a segment of the Naga-Patkoi range comprising the northern tip of Indo-Myanmar (Arakan)
mountain range made up of folded Tertiary sediments, mostly sandstone and shale.
The state is rich in mineral deposit of graphite, limestone, coal along with significant deposits of
quartzite, basemetals and minor PGE mineralization. Reserve of 342mt limestone, 246.75mt dolomite,
86.15mt graphite, 90.23mt coal and 5.15mt quartzite are the main mineral deposit of the state. Beside these,
state has hydro-electric potential of 33,850 MW in different basins.
The coal is located mainly in Namchik-Namphuk area and Miao Bum area in the eastern part of Tirap District.
A linear belt of 350 km from Haflong in Assam in SW to Namchik-Namphuk area of Arunachal Pradesh in
NE holds promise of presence of more Tertiary coal.

Assam: The major part of the state is covered by recent alluvium of east - west trending Brahmaputra plain.
The Karbi Anglong Hills & North Cachar Hills located at the central portion comprising of gneisses and
schists with granite intrusions and folded Tertiary sedimentaries of the Naga-Arakan sequence respectively
and the Cachar plain in the south comprises of recent alluvium. Crude oil is the most important natural
resource of Assam. The state has a reserve of 513.31mt of coal, 394mt of limestone, 30mt of iron ore, 13.4mt
of silica sand, 2.0mt of fireclay, 13mt of clay along with high potential of granite, sandstone and mica.
Crude oil is found in upper part of Tertiary Barail sequence, where largest amount of oil is discovered
in this region so far, while Tipam sandstone is another important oil productive horizon. In the shelf zone, oil
was discovered just above the basement at Borholla and gas in Eocene sand near Tengakhat
2
The coal occurrences in Assam are reported from two geological horizons viz., Gondwana and
Tertiary of which Tertiary coal deposits of Makum, Mikir Hills and Dilli-Jeypore are the most important
coalfields. The Tertiary coal deposits of Makum, Dilli –Jeypore and Mikir Hills area are the major coal
resource of the state. The coal deposits in Mikir Hills occur within Sylhet Formation of Jaintia Group and are
located in the southern part of Mikir Hills and to the north of the railway line between Lumding and Dimapur.

Manipur: Apart from the 1850 sq km of Imphal valley in the middle, the rest of Manipur comprises north-
northeast trending steep ridges of the Naga - Arakan Tertiary sedimentary sequence comprising sandstone,
shale, siltstone and limestone is emplaced by ultramafic suite of rocks along the Myanmar border. The
Manipur ophiolite belt composed of intimately juxtaposed slices of mafic- ultramafic rocks is a product of
“obduction” resulted due to the collision of Indian and Burmese plates during Tertiary period. The principal
mineral of some economic significance in Manipur is limestone (10.6mt). The proved reserve of lignite is of
the order of 12,262 tonnes, and that of clay is 2.52mt. Beside these Manipur is rich in chromite and dimension
stones.
Meghalaya: Geologically, Meghalaya is mainly comprised of Precambrian Gneissic Complex and Shillong
Group of sedimentary rocks, comprising of conglomerate-quartzite-phyllite sequence unconformably overlies
the Precambrian Gneissic Complex. The Khasi Basic-Ultrabasic Intrusives of Meghalaya comprising basic
intrusives like epidiorite, metagabbro, metadolerite, etc occur mostly as sills, dykes and rarely as phacoliths in
the various subfacies of the Shillong Group. A number of Neo-Proterozoic granite bodies, often of batholithic
size transect both Gneissic Complex and Shillong Group in Meghalaya. Notable among them are the Sindhuli,
Rongjeng, Kyllang, Mylliem, South Khasi, Kyrdem and Nongpog granite plutons, exposed along the eastern
and southern rims of the plateau, is a near complete sequence of Tertiary sediments overlying the volcanic
suite of Sylhet Traps. The state of Meghalaya is endowed with huge resources of limestone (9804mt.)
particularly in the Tertiary rocks occurring in Jaintia, Khasi and Garo Hills. Meghalaya has coal reserve of
576.48mt. Other important mineral resource of Meghalaya are Polymetallic basemetal mineralization of 1.18
lakh tonnes, 406,400 tonnes of glass sand, 6.5 million tonnes of crude clay, 4.56mt of apatite and considerable
amount of granite (for dimension stone). Tertiary coalfields of Garo Hills are located along the southern
extremity of Shillong plateau as scattered patches. Coal occurs in the Tura Sandstone (Eocene) of Jaintia
Group. The Gondwana coalfields of Meghalaya restricted only in the Garo Hills are exposed in the Singrimari
basin on the north-western corner of Garo Hills bordering Dhubri district of Assam. The coalfields of Khasi
Hills are located in the southern periphery along the international boundary with Bangladesh.

Mizoram: A repetitive succession of young Tertiary sediments, mostly shale, siltstone and sandstone, tightly
folded into a ridge and valley sequence comprise the whole state. Along the somewhat broad valleys in the
northern part, bordering Assam, recent alluvium covers the sediments. There is some potential for oil and gas,
lignite, decorative shell limestone, sandstone slabs (as dimension stone) and clay body within the
sedimentaries.There is some potential for oil and gas accumulation in the folded sedimentaries. There is scope
for hydel power generation in the state on a large scale along the Kolodyne and Tuivai rivers and as
microhydel schemes along many smaller streams. Indication of oil, saline springs and a few gas seepages in
the central part of Mizoram are reported. Salt spring has been located north of Sabual village in western part of
Mizoram. Occurrence of 3 metres long and 10 cms thick, grey, pyrite-bearing, lignite patch in ferruginous,
brownish, yellow, soft, Bokabil sandstone has been reported south of Chubel village. About 6.5 kms southeast
of Ngopa, a few lenticular pockets of coal have been recorded. Streaks, stringers and patches of coal are found
in the Upper Bhuban Sandstone. The Mizoram state Department of Industries (Geology and Mining Wing) has
proved 5200 cubic metres of decorative shell limestone at Ngrum Lui near Turial Bridge and 6000 cubic
metres at Sesawang. A thin horizon of clay is noticed northwest of Borai, near Momchera and in the valley
near Plura village. The clay has a vast potential for making bricks.
Nagaland : Geologically, Nagaland comprises Tertiary sedimentary rocks of Disang, Barail, Surma and
Tipam Groups that form the northern extension of Arakan-Yoma ranges, while the younger alluvial sediments
occupy valley areas. NNE-SSW trending ophiolite suite of rocks represented by mafic- ultramafic sequence is
juxtaposed with Naga metamorphic belt along the eastern margin all along the contact with Myanmar. In
Nagaland, occurrences of major minerals are limestone (375mt.), coal (315.41mt.) and nickel-cobalt bearing
magnetite. Sulphide (Cu-Fe) occurrences are noted in chert-volcanics and mafic-ultramafic association of
ophiolite belt at some places of Phek and Tuensang Districts. Oil and natural gas occur in western foothill
areas and Schuppen Belt, being trapped in fractured and weathered basement rocks, and in the overlying
Tertiary cover sediments of Kopili / Barail / Surma / Tipam rocks.Coal deposits, which occur in Tikak Parbat /
Jenam Formations of Barail Group, are located in Borjan-Tiru areas of Mon district, Changki-Chongliyimsen
and Lakhuni areas of Mokokchung district, Leo Longidang area of Wokha district and Konya area of
Tuensang district.

Limestone Investigations: Investigation for Limestone (G3) is in progress in North of Larket Block,
Litang Valley, Jaintia Hills District and Mawlong-Ishamati Block of Shella - Bholaganj Belt, East Khasi
Hills District, Meghalaya. Earlier investigation for Limestone in Umphyrluh Block, Litang valley, Jaintia
Hills District was completed in November, 2013 as an extended item of FS 2012-13 in which 1.5 sq. Km
of detailed mapping was carried out. Drilling of 907.85m and 692 core sampling was done in which
drilling of 675.40 m and 417 core sampling was achieved upto Dec, 2013 for FS 2012-13 which makes a
18
total of 1583.25m and 1109 nos of core sampling. In addition to 439.29 million tonnes of different grade
of limestone estimated during F.S 2010-12 which is based on fifteen boreholes, a resource of about 64.43
million tonnes of different grade of limestone was estimated for the three boreholes of this block.
Geologically the Larket block exposes mainly the Middle Tertiary Sedimentary sequence comprising
Kopili and Shella Formation of middle to upper Eocene age with cover recent to sub recent alluvium. The
Shella Formation is represented by nummulitic limestone. The limestone is grey to dark grey in colour,
medium grained, massive, compact and highly fossiliferous, dominant fossils being nummulites while the
Kopili Formation is represented by shale and ferruginous nummulitic argillaceous limestone/marl. Shale
is dark in colour, thinly laminated and splintery in nature.
The general trend of the Formation is sub horizontal with strike varying from NNE- SSW to NE-
SW and dip varying from 30º to 50º towards ESE to SE. Three sets of joints are developed in the
limestone, out of which two are vertical to sub vertical trending NW-SE and NNE-SSW. Stylolite with
varying magnitude and wavelength are the common solution structure present in the limestone.
Disseminations of pyrite is observed along the fractures of drill cores, Oolitic structures showing
concentric carbonate rims of various shapes and size ranges from few mm to 2.30 cm across. Ball and
pillow structure are also seen in the drilled core.
During FS 2013-14, in the Larket block, drilling commenced on 23.12.2013 and progressed up to
281.75m in which 112 nos of core sampling was done till March, 2014. The remaining drilling target of
FS 2013-14 will be carried over during FS 2014-15. Borehole no.JNLK-1 was closed at depth of 89.10m.
Borehole no. JNLK-2 commenced on 10.02.2014 and attained a depth of 51.50m in which limestone band
ranging in thickness from 79.00 m to 95.00 m has been intersected at shallow depth. Limestone resource
of 43.89 million tonnes of unclassified category has been estimated from borehole no. JNLK-I and JNLK-
2. To assess the potentiality of limestone along the western continuity of Mawlong-Ishamati Block, Shell-
Bholaganj belt in which 1.5 sq. km area has been mapped on 1:5000 scale. The lithounits encountered in
the area are limestone, shale and sandstone. The northern part of mapped area occupied by E-W trending
limestone ridge of 80 m to 100 m in height with steep slope. Limestone is hard and grey in colour and
trend along E-W direction with variable dip from 35° to 45° towards north. The limestone belongs to
Shella Formation of Palaeocene-Eocene age. Petrographic studies of limestone shows predominant
presence of foraminifers with large amount of other fossil shells. Few veins of pyrite were observed
within limestone in western part of the area.
Shale of Kopili formation of Palaeocene-Eocene age occurs in south of limestone ridge. It is
highly weathered, splintery in nature and shows variable dips in the area. The contact between limestone
and shale is faulted and trends E-W. The Kopili shale is younger but in the area it lies in down thrown
block. Sandstone band of 20m to 30m wide was also demarcated within the shale. Sandstone is fine to
medium grained and grey in colour.
Analytical results of 7 grab samples collected from of limestone ridge shows an average CaO
50.75%, Fe2O3 0.21%, MgO 0.81% and SiO2 3.51%. The analytical data indicate chemical grade of
limestone. In this block subsurface exploration by drilling (RD-30; Unit No:441) commenced on
28.03.2014 in which three boreholes has been taken up (one completed and two in progress). Total
meterage achieved in all the boreholes in this Block was 83.10 meters in which 22 nos. core samples were
generated till March, 2014. The first borehole ISBH-1 was planned to intersect the western continuity of
limestone of Mawlong-Ishamati block. This borehole drilled up to 54.75m and intersected boulders of
limestone, sand and clay. Borehole no. ISBH-2 was planned at 120m west of borehole no. ISBH-1 to find
the lateral continuity of limestone bands towards west. The borehole ISBH-2 progressed up to 23.85m
and was suspended due to break down of drill machine (Unit-462). It has intersected fossiliferous
limestone with occasional calcite veins. 22 nos. of core samples were collected and submitted for
analysis. Results of core samples are still awaited. Borehole ISBH-3 was planned further 400m west of
Borehole no. ISBH-2 and drilled up to 4.50m depth (31.03.2014). It has intersected fossiliferous
limestone and bore hole is in progress.

granite and non-porphyritic granite of Nongpoh pluton. Three generation of Nongpoh granite/granitic
events have been identified on the basis of field relationships. These are Early Non-porphyritic Granite,
Porphyritic Granite and Late Non-porphyritic Granite. Three types of enclaves viz; xenolith of country
rock, dark grey porphyry and black biotite rich microgranular enclaves were observed in Nongpoh
porphyritic granite. The mafic enclaves (MEs) in the area have various shapes including circular,
rounded, ellipsoidal, angular to sub angular, as dykes. The mixing compatible textures observed during
petrographic study viz; acicular and stubby apatite, resorbed plagioclase xenocrysts, titanite-feldspars
ocellar relation, ocellar quartz, poikilitic microcline, plagioclase, hornblende and quartz, combined with
frequent occurrence of MEs of various shapes and size suggest magma mixing and mingling was a major
process during the evolution of Nongpoh Granitoids. SSS data of 8 nos. samples yield ∑REE (La-
Lu+Sc+Y) value range between 226 to 2984 ppm with an average value of 900ppm. One sample contains
2984 ppm at the contact of porphyritic granite and basement gneiss. BRS analysis of 9 samples of
Porphyritic granite yield ∑REE (La-Lu+Sc+Y) ranges between 562 to 980ppm with an average value of
813ppm. 6 samples of Non-porphyritic granite yield ∑REE (La-Lu+Sc+Y) ranges between 578 to
2148ppm with an average value of 1152ppm. Two granite samples yield ∑REE (La-Lu+Sc+Y) value
1803 and 2148 ppm have visible spindle shaped sphene (titanite) and allanite (?) in hand specimen. One
sample of Granodiorite (?) from Garikhana area yield ∑REE 813ppm. 06 nos. soil samples yield ∑REE
(La-Lu+Sc+Y) value ranges between 653.57 to 1614.50ppm with an average value of 1041.92ppm.
EPMA analysis of Nongpoh Granitoids indicated presence of REE Carbonate (70.65% tREO), Monazite
(61.16% tREO), Allanite (18.52% tREO) and Sphene (2.4-4.1 %tREO). Apatite and zircon contains very
less (<1%) total REO.

Specks and disseminated grains of pyrite and chalcopyrite are observed in gneisses,
diorite/granodiorite, mafic intrusive rock, porphyritic granite, quartz and pegmatite veins. Sheelite grains
have been identified by EPMA study in garnet-epidote rock which are observed in porphyritic and grey
non-porphyritic granite. Disseminated magnetite crystals in the pegmatite intruding in grey granite was
observed (west of Mawdaran). Two samples collected from granite and associated pegmatite near
Mawdaran village shows 7 ppmm & 36 ppm Mo at Mawdaran quarry.
Titaniferous-Vanadiferous Magnetite Investigation: Titaniferous-Vanadiferous Magnetite
Investigation around Rambrai in West Khasi Hills district, Meghalaya is in progress. An area of 25
sq.km has been mapped on scale 12,500 in which lithounits encountered in the area are granite gneiss,
banded gneiss, granite and mafic granulite. The granite gneiss is medium to coarse grained with a crude
foliation. It is mainly composed of quartz, Plagioclase, feldspar, biotite. Tourmaline and magnetite are
accessory minerals. At places granite gneiss is highly weathered and shows a typical banded nature
defined by 3-4cm thick quartzo-feldspathic layers intervened by thin mafic layers. Three meta norite
bodies of different length and width have been identified and delineated in the area viz., (i) Northwest of
Moulih, (ii) West of Rambrai, (iii) Southwest of Rambrai. These bodies trending NW to WNW direction.
The rock is dark grey colour, fine to medium grained and massive. The first two meta-norite bodies are
having bands of titaniferous-vanadiferous magnetite and partially laterised. The dominant foliation within
the gneiss is trending NW-SE with moderate to steep dips towards NE. Two prominent set of sub-vertical
joints trending NE-SW and E-W also observed in the area.
Large Scale Mapping on scale 1:2000 was done of an area of 1.10 sq.km near Moulih
village and pitting and trenching of 3.20 cu m was carried out. The meta-norite body is bouldery in nature
and trending NW-SE dipping towards 40°-60° SW. The bed rock samples were collected for XRF, PGE
and REE analysis. Mineral phases identified by EPMA study are. Ilmenite, Titaniferous - Vanadiferous
magnetite, Chalcopyrite and Pyrite. A total of 60 nos. of bed rock samples were collected for which
analysis of 26 samples (XRF) received so far shows Fe2O3 ranges between 6.82% to 30.96% (average
14.03%),TiO2 0.72% to 4.30% (2.06%), Vanadium 81ppm to 1398ppm (688ppm), Zr 47ppm to 1802ppm
(205ppm) and copper from 5ppm to 566ppm(188ppm).

Mission–IV: SPECIAL INVESTIGATION, RESEARCH & DEVELOPMENT
Palaeontological Studies:A field investigation was taken up along Shillong-Sohra, Shillong-Mawsynram
and Shillong-Dawki in East Khasi Hills district of Meghalaya for search of fossils and preparation of
geological map on 1: 50,000 scale. Twenty four (24) specimens have been collected covering 17 sq km of
the area. 10 L.km. mapping was done and 5 sections measured. Trace fossils like burrows, bi-valve resting
impressions etc. were collected from Mahadek and Langpar Formation along Shillong-Sohra, Shillong-
Mawsynram and Shillong-Dawki sections. Numerous wood fossils were collected from Langpar Formation
along these sections. In case of invertebrate fossils, Allectryonia sp., Nummulites sp. etc were collected
from Mahadek Formation and Shella Limestone respectively. Most interesting part is that, about dozen of
oval to rounded egg fossil like samples were collected in and around Dawki area, East Khasi Hills District,
Meghalaya and these were examined physically and thin sections were prepared at different directions
(tangential & radial). The SEM-EDX study and thin section study of the suspected egg shell were carried
out at Palaeontology Division - I Laboratory, CHQ, Kolkata. EDX study shows that these samples contains
very high calcium which in turn suggests that these are fossils not phosphatic nodules. SEM study shows
presence of pore spaces in some samples. Few thin section studies show egg shell structure and pore spaces
in tangential section. Radial thin section was prepared and studied but they do not shows typical
canaliculae of tubocanaliculate pore system which is the characteristic feature of egg shell of reptiles.
Detailed study of thin section in SEM and EDX graphs suggests these are not egg fossils but are
invertebrate fossils falling within gryphoid group, most of them are possibly algal balls and a very few are
possibly erosional features within limestone.
Geotechnical investigations:NER may be termed as the ‘power house’ of India as it possesses
hydropower potential, which is about 30% of the total hydel potential of the country. The hydel potential
of major river basin of Arunachal Pradesh like Kameng, Subansiri, Siang, Lohit and Dibang totals
production of 34920 MW at 60% load factor (CEA) i.e. about 90% of the total hydropower resources of
NER.
A large number of major and minor hydroelectric projects have been completed or are under
various stages of investigation/construction with the active help and support of geoscientific inputs by the
GSI, e.g. Ranganadi, Doyang, Umiam (Barapani), Pare, Kopili, Turial, Kameng, communication projects
and border roads.
Arunachal Pradesh contributes a major share of the water of the Brahmaputra river system and the high
relief offers extensive scope for hydel power generation. Geotechnical evaluation of water resources
development projects in North Eastern Region has been taken up at the request of the project authorities.

Macro-scale landslide hazard Zonation (1 : 50,000) of the Hayulinag –Challagam and Teju- Hayuliang
road sector of Lohit and Anjaw district of Arunachal Pradesh was carried out with the aim to prepare a
landslide susceptibility map of the selected stretch and evaluate the overall stability of the area in respect
to future landslide initiation. As a part of the exercises the 150 line km of the road bench between Teju in
26
the Lohit district and Chaglagam in the Anjaw district has been covered for augmentation of thematic
data bases and preparation of the landslide susceptibility map. A significant observation made during the
study is the nature and quantum of coarse debris being carried out by all the mountain streams. A huge
volume of debris mostly boulder laden is found to be transported by nearly all the streams and the trunk
rivers in the area. The same along with near absence of finer fractions in the riverine material may be
explained in terms of rejuvenation of the stream under the influence of neo- tectonic activities. As a part
of the work 56 numbers of the active and reactivated landslides were identified and mapped. Among these
31 are rockslides, 22 are debris slide and 3 are debris flow. Along the observed section the rock slides
found to be the dominant one. Both old rock slides and large/prominent new rock slides found traversed
the slope and affecting the road bench, upslope and down slope in the studied area. Planar failures,
combination of planar and wedge failure as well as toppling are the major identified failure mechanism.
Apart from the rockslides the other major kind of slope distressing that was observed and documented in
the area are Confined/at places unconfined debris flow initiated at high slope and descended through
majority of the mountain streams. The major outcome of the work besides the preparation of thematic
maps is i) Identification and documentation of the predisposing, triggering and revealing factors for
landslide initiation .ii). Detailed inventory of the observed slope instabilities encountered in the studied
corridor. iii) Detailed evaluation of a few trouble spots for understanding of the causative factors, failure
mechanism and formulation of suggested remedial measures. iv) Perspective assessment of the landslide
initiation process based on the revealing factors, slope morpho-metry, stream configuration and nature&
amount of sediments load in the drainage.
Detailed (1:1000) Site Specific Geological Studies of the Landslides near Tawang Monastery,
Tawang district, Arunachal Pradesh has been carried out for comprehensive evaluation of the various
attributes across the large dynamic slope mass of the conspicuous landslides near famous historic Tawang
Monastery.The slope failures initiated at least before 1985 is being continuously evolving in space and
time covering more than 0.6 sq km area is responsible for significant administrative and social concern
due to its proximity to the famous Tawang Gaden Namgyal Lhatse (TGNL) Monastery (popularly known
as Tawang Monastery), founded in the year 1680-81. The studies reveals presence of multi-level slide
scrap of varying dimension and geometry, initiated and evolved in varying slope forming material was
identified along and across the landslide complex. The prominent among the slide scars is the
conspicuous curvilinear crown scar extending over 100 m and subsequently found joined with the
prominent left side scars. Corresponding to the zone of depletion proximal to the scarps, a prominent
zone of accumulation in the form of gently sloping bench could be identified. The material identified
along and across the affected slope are isolated exposure of slight to moderately garnetiferous quartzo-
feldspathic gneiss, highly weathered Gneiss, in-situ soil, failed debris mass, mud flow and debris flow
deposits. The attitude of gneissosity varies from N180-300E/160-280→S780E (dipping inside hill) to
SW. Besides, the rockmass is traversed by three joint sets. Deep rotational failure in the in-situ soil and
failed debris mass, shallow and deep translational failure in the weathered rock mass, large block
subsidence in the flank were identified for initiation of slope failures at various space and time. Multiple
episode of debris/mud flow of varying run out length initiated in pulses is identified as one the important
mode of slope failures. The unconfined debris/ mud flow with significant momentum descended down
slope and are found partially submerged a school (Kendriya Vidyalaya). The most prominent debris flow
observed was initiated from upslope accumulated debris found descended along the moderately steep left
bank slope of Kangteng River through two branching type of confined flow path and accumulated heap
near bank of the Kangteng River. Partial blockade of the river due to the flowing debris mass was also
noticed along the left bank for more than 100 m. Reactivation of some of the failure surfaces along the
prominent scars is also anticipated. The controlling law and parameters of the different stages of failure
and consequences of the same to the element at risks are being evaluated through detailed studies. As a
part of the endeveour nine (9) suitable borehole locations were delineated to understand the spatial and
temporal variation of the bedrock across the landslide complex. The field based findings will form the
basis for comprehensive understanding of triggering mechanism and causative factors responsible for
initiation and further continuation of failures to the upslope.
Detailed Study of 13th mile slide on Gangtok-Nathula Road, East District, Sikkim was carried
out. An attempt was made to study the slope stability on the eastern flank of the slide using slicing
method of Morgenstern-Price. During the stability analysis, the Factor of safety values ranging from 0.76
to 0.89 (in dry conditions) and from 0.72 to 0.84 (in wet conditions) were acquired indicating that the
slope is more vulnerable in the wet season. As the road passes mostly through the crest of the distress
27
zone, it is proposed from one Stability analysis, that the road may be shifted above the exposed rock line
upslope of road bench or to construct a retaining wall up to a depth of 48m for the road in its current
position. Using the monitoring data, strain analysis indicating the parts of the landslide where pillar nos.
1,2,3,5,6,7,9 and 16 are present in a compressive zone relative to others. The velocity and displacement of
installed pillars indicates a general displacement of the landslide in the SE direction.
Macro scale landslide hazard zonation on 1:50,000 scale along Rangpo-Singtam-Dikchu-
Chungthang road corridor, Sikkim Macro scale (1:50,000) was carried out to categorize the hill slope
into zones of varying degree of hazards (instability) and understanding the extent of new landslide
initiation and reactivation of the old landslides aftermath of the 18th September, 2011 (6.8 Mw) Sikkim
earthquake. As it is very much important to look into the landslide hazard zonation map from time to time
specially after every major earthquake (>5 on Richter’s Scale), and the selected corridor which is one of
the major passage connecting towards North Sikkim and densely populated townships viz. Rangpo,
Singtam, Dikchu, Mangan, Chungthang and major hydel projects namely Teesta stage III, IV and V falls
along this road corridor and in view of the post Sikkim earthquake scenario. A total of 42 nos. of
landslide incidences were recorded from Rangpo to Tung road corridor and most of them are of Rock
cum debris slide in nature. Almost 81% of the study area from Rangpo to Tung is falling under
moderately steep to steep slope having range from 26⁰ to 45⁰. Minimum relative relief is 35m near
Rangpo where as the maximum is 1835m found near Mangkha village. Landuse/Landcover map have
been prepared by using all available satellite imageries including LISS-III data and which has been
validated with field checks. About 80% land is barren with forest cover, 15% have agriculture and 5%
land is utilized by settlements.
A total of 23 sq. km area is covered out of 25 sq. km under geological mapping on 1:25,000 scale
was carried out for the Site specific study of proposed Pakyong airport area, Sikkim. The main lithounits
in and around Pakyong area belongs to Gorubathan Formation of Daling Group represented by low grade
metapelitic rocks, phyllite and schist with thin intercalations of quartzites. The trends of foliation are
varying from NE-SW to NW-SE dipping either easterly or westerly. Slope morphometry map has been
prepared which was derived from DEM. Major part of the study area belongs to gentle slope, followed by
very gentle slope and moderately steep slope and steep slope. The highly steep slope category occupies
very small portion of the area. The lineament map has been prepared for 100 sq.km. area in and around
Pakyong area. Majority of large lineaments follow NE-SW to NEE-SWW trend, whereas some
lineaments also have N-S, E-W and NW-SE trends. Drainage map has also been prepared from the
toposheet. The main drainage of the area is Pachey Khola which is a tributary of Rangpo Chhu. Slope
facet being basic unit of Landslide Hazard Zonation (LHZ), the map was prepared from toposheet and a
total of 1025 nos. of facets have been identified from 100 sq. km area. Relative relief map has also been
prepared from which it can be found that, major part of the studied area is characterized by high relief
(49.48%). Next to this, medium relief occupies 45.70% and rest of the area (4.8%) belongs to low relief
category. Landuse and landcover map, which is an indirect parameter governing slope stability have
been prepared after field check. Major part of the study area is agricultural land with isolated houses. The
densely populated land is mainly concentrated in the Pakyong town. The landslide incidences and
subsidence are mostly concentrated in the moderately steep slope of the northeastern part of the proposed
airstrip as compared to the other parts of the study area and various sinking zones are observed which are
mostly concentrated in the vicinity of the perennial nalas.

km within the Aizawl master plan. Collected 10 nos. of undisturbed soil samples and 5 nos. of rock
samples for analysis of different geotechnical parameters. The collected rock and soil samples were
submitted to Geotechnical Laboratory, Eastern Region for analysis of relevant geotechnical parameters.
Geologically the area is represented by a thick sequence of arenaceous and argillaceous sediments
28
belonging to the Bhuban Formation of Surma Group. The litho units occurring in and around the
Muallungthu to Hualngohmun areas are dominantly by bedded silt shale / shale sequence with few bands
of siltstone and sandstone intercalation. Various thickness of over burden in the form of colluvial
material and highly weathered mantle rocks occupy the gentle slopes, whereas along the spur surfaces
the thickness of overburden ranges from 1 to > 5 m in the above mentioned areas. Lungleng, Sairang and
Tanhril areas are occupied by dominantly massive thickly bedded sandstone interbedded with thin bands
of shale/ silty shale overlained by thick weathered mantle and soil on the gentle slope and spur surface.
Aizawl master plan area falls on the N-S trending broad and asymmetric antiform with axes shifted
laterally at places. These are traversed by sets of E-W trending fault systems which are having distinct
geomorphic expressions of faulting. Different slope forming materials like highly weathered mantle
rocks and colluvial materials ranging its thickness from 1 to 8 m thick were studied and mapped for
arriving at the site response / landslide hazard assessment. In general the rocks in the study area trends
NNE-SSW to NNW-SSE with moderate to high dips on either sides. Synthesis of seismicity data within
300 km radius in and around Aizwal area, involving conversion of Ms and Mb earthquake magnitudes to
Mw for assessing the recurrence period and to determine PGA of the area was undertaken.During the
course of the study Landslide inventory were carried out in and around the Aizawl master plan area as
well as along Sairang – Kanpui road section. It appears that the slope instability can be attributed to the
inherent rock mass condition, anthropogenic interference (unscientific slope cutting / static loading due
to constructional activities), unguided drainage, etc. Besides, ground water information based on the
available hand pump locations were recorded and are being analysed with other collateral subsurface
information collected from different Government agencies. The collected field data are being processed
for the preparation of relevant thematic maps for analysis and interpretation regarding the Seismic
Hazard Assessment of the area.
Kohima City, Nagaland: Analysis of past seismicity data of 300 km radius around Kohima city was
carried out to delineate potential seismic source area. The analysis has indicated high seismic activity
along the Eastern Boundary Thrust Fault which is located about 83kms south/southeast of Kohima.
Moderately high seismic activity along the Belt of Schuppen, Kopili Fault and Shillong massif
Seismogenic zone was also observed, which is located within 100kms and 200kms respectively from the
Kohima area. Study and synthesis of rainfall data for 30 years of the study area, provided by the
Department of Soil and water conservation, Government of Nagaland was also undertaken. Synthesis of
this data was undertaken for estimating the recurrence period and PGA value. The Morphotectonic and
lineament map covering 50 sq. km area was prepared using LISS-III and SRTM data of Kohima area.
The study area is located in a fold thrust tectonic set up of the Belt of Schuppen comprising of 5-6
tectonic slices bounded by the Naga Thrust and the Haflong - Disang thrust in the north and the Eastern
Boundary subduction zone in the south. Surface Geological Mapping on 1:25,000 scale covering 17 sq.
km around the areas of New Secretariat complex, Merema, High school area, IG stadium and Zubza
river section of the Kohima Master Plan area was undertaken. Highly weathered carbonaceous shale of
the Disang Group of rocks are exposed in this area, which trends NW-SE with moderate dips towards
NE. Facet wise data collection on different geo-factors like lithology, structure, landuse / landcover,
hydrological condition, etc. covering an area of about 17 sq. km in the southern part of the study area
was undertaken for landslide hazard zonation. This data is being synthesised to arrive at different hazard
levels in the area. Slope instabilities studied in this part of the area revealed that the weak rock mass
(highly weathered shale), toe erosion of the slope, saturated slope wash material and construction of new
road across the slope have resulted in the instability of these slopes. Although some part of the area is
slightly away from the main settlement, the instability in this zone has an impact on the agricultural land
and the settlement on the top part of the slope. Besides, study of groundwater information along with
borehole litho log collected from the Directorate of Geology and mining, Govt. of Nagaland was also
carried out. Four soil and two rock samples were collected and all the samples were submitted to
Geotechnical Laboratory, Eastern Region for analysis of relevant geotechnical parameters. Presently the
work is under progress and will be continued during FS 2014-15, the second year of the study.
Study of active landslide incidences within the Master plan area like the Phesama slide, old dumping
slide along NH-29 and Merema slide along NH-61 were also undertaken and the causative factors of the
slide, morphology of the slide, etc. were studied and appropriate remedial measures were suggested.
Three rock samples of fine grained sandstone of Laisong Formation (Barail Group) and one rock sample
of Shale (Disang Group) were collected for analysis of different geotechnical properties.

Gangtok, Sikkim: The Seismic Observatories installed at Agartala (Tripura), Itanagar (Arunachal
Pradesh) and Adampool, Gangtok (Sikkim), which are equipped with broadband seismographs, are being
used to record the seismicity round the clock of the North Eastern Region and its adjoining neighboring
countries, such as Bhutan, Nepal, Bangladesh, and Myanmar. These Observatories are very useful for
providing potential information on earthquake genesis of the eastern Himalayan region as well as sub-
oceanic earthquakes from the Bay of Bengal, which will be helpful in evolving earthquake mitigation
model for the region as a long-term goal. Study of toposheet and SRTM data to delineate different
geomorphic /morphotectonic units and Lineaments. Seismic Hazard Assessment of Gangtok and
surrounding areas of Sikkim were initiated by State Unit: Sikkim. Seismic Hazard Assessment of
Gangtok , Sikkim was carried out by Site response study was carried out by three component digital
seismograph (Kinemetrics make SS-1) using H/V method developed by Nakamura (1989) to eliminate the
source effects in the spectra of the micro tremor signal. Preliminary analysis shows a moderate site
amplification factor (HVSR) varying between 3-5 in the eastern part of the study area which includes the
Gangtok town and extends to the station G1 (Gairgaon area) in the south. Recording of ambient noise for
Seismic site response study in Gangtok and surrounding areas was carried out. For 50sq area, Site
response study by measuring ambient noise using short period Seismograph at every 1-2 km. station
spacing have been completed. Surface Geological mapping on 1:25,000 of 50 sq. km Geological
mapping on 1:25,000 scale was completed in and around Gangtok along with 5 L.km Profile section /
measurement. 25 nos. soil samples for Geotechnical properties were collected and send to GT Lab, ER,
Kolkata. High site amplification is observed close to site S6, (Slave ground) in the northern side of the
study area which lies in the flat ground with gentle slopes on both sides, whereas, high amplification in
the south near to N2, lower Nagdok, is on the steep slope side near to the valley. The site P8 (Pastanga) in
the south also shows high amplification on the gentle slope in the valley edge. Most of the area in the
western part has comparatively low amplification zones where HVSR varies between 1 and 3, except at
stationT4, where the site is on a flat hill top with a thick soil cover.
Medical Geology: Systematic spot analysis of groundwater and surface water by Merck Arsenic Field kit
were carried out in the field in Toposheet 83 B/12 & B/16 to study of arsenic contamination in water and
soil in parts of nagaon and marigaon districts, Assam. The arsenic values in groundwater varies from nil
to 100 ppb where as that of surface water varies from nil to 5 ppb. Exceeding the WHO’s permissible
limit i.e. 10 ppb, 47 nos. samples of groundwater collected from handpumps and tubewells have recorded
arsenic values of 25 ppb. One sample in TS 83 B/16 has arsenic 100 ppb in Nis Daboka and two samples
have arsenic values 50 ppb. The depth of handpumps varies from 30 to 50 ft b.g.l and tube wells vary
from 200 to 400 ft b.g.l within younger floodplain in the area. The concentration of high arsenic values in
groundwater occurs as small zones/clusters near villages Raha, Chapermukh, Kusigaon, Darangigaon,
Guimari, Saragoan, Tetchgarh, Bhagtakagaon, Charaihagi, Jamunamukh, Kampur and Tetlisarah villages.
10 ppb values of arsenic have been recorded in Tapakushi, Molankata, Jorabari, Kothiatoi, Kampur,
Barkula, Atikampur, Tetlibora, Saraipather,Kondoli, Bindura, Paraiguri, Middaimargaon, Hariamukh. In
other villages, the value of arsenic ranges from 0 to 5 ppb. The surface water samples values of Arsenic
range from 0 to 5 ppb. The high arsenic values occurring as zones were transferred over the geological
map shows that most of the high values occur within the Newer alluvium sediments of Barpeta and Hauli
Formations. Older alluvium sediments are devoid of arsenic contamination thus having fresh water.

Besides, the systems & support - as above, Geodata Laboratory extends infrastructure and
personnel support in carrying out various office work and technical work on digital concepts, as desired
time to time by the administration, RTI and divisions. The division is the centre for personnel support in
MAP items of FSPs and maintenance of regional spatial-data repository. The spatial data from the
repository is over plotted to compose maps for their delivery. Majority of the purchase of IT products,
i.e., Hardware and software have been carried out by the APM&D of the Region on the specifications
prescribed by the Geodata Division, on received requisitions from and requirements of divisions and
sections.
The www.portal.gsi.gov.in is the portal for the Geological Survey of India. This web based IT
development is catered through centralised servers at CHQ, Kolkata. The LAN or WAN/ WiFi connected
systems at RHQ and State Units in NER operate on BSNL Telephone Line (WWW) / Lease Line to run
the Portal. Like the other region, the desktops and systems are procured at / supplied to Guwahati,
Gangtok, Itanagar, Dimapur, Agartala - the HQs for SUs , and Shillong - the RHQ, in NER. Barring the
stand alone systems to carry out dedicated Office and Technical work, the other systems are on the Net.
Majority of these systems have foundation on Windows XP operating system switching to new supplies
with Windows 7 in light of migration from IPv4 to IPv6 address system on the NET. WAN / Lease Line
is in effect in the premises of NER from February 2009.
STATUS OF NETWORKING & IMPLIMENTATION OF PORTAL AT GSI, NER
Portal Phase I (Installation of LAN at RHQ and SUs):
Infrastructure: Installation of LAN at RHQ: GSI, NER, Shillong is operating from several rented
buildings at Shillong. Local Area Networking exist at three premises viz., Shylla building, Kumud villa
and building at Motinagar. Regional headquarters of NER, TCD, TCS and LHZP is functional from
Shylla building. Where as Petrology, Palaeontology, Publication, M&C and Chemical Divisions with
their laboratories form a clusture about Kumud Villa. With its laboratory of the Geodata division and
Administration run from a building located at Motinagar.
Lease line runs for portal access into the networks on upgraded 1 MBPS bandwidth. Internet connection
to the office premises frequently marred by interruptions or out of the reach situations on the networks in
Shillong which are on BSNL broadband and WiFi devices.
LAN infrastructure is not-feasible in buildings other than the stated three LAN net workings.
Recently, Wi-Fi access points have been put on broadband line to these buildings. This gives a lean
access to portal and internet in these deprived buildings. Since second quarter of 2013 offices of Mission-
I, II, III & IV and RTI have occupied two rented buildings close to Kumudvilla. These buildings are in
need to develop networking so that the divisions have the access to the portal. WiFi Access points on
BSNL Telephone Lines have been installed in these two buildings (Mission-I, II and Mission-III & IV) as
a temporary measure to extend the internet support to the DDGs (Missions, recently posted to NER). The
WiFi Systems started their operation in the last two quarters.
Portal Applications: All the officers and staff of State Units and RHQ have been given training on the
various transactional applications, in phases, on GSI Portal and modules therein.
With acquisition of approval on FSP items, the divisional heads start loading relevant items to GSI Portal.
Many a times, they come across problem in loading. On reporting the faced problem the Geodata tries to
resolve, at its laboratory, but at times when Geodata identifies some complex issues in process, it get this
rectified through the Help Desk at CHQ.
Officers and staff, on policy based - for short period (2 to 3 years) of time, are posted in NER. In
coming into and out going from the region on transfers, is normal phenomenon. A post holder leaves or
joins, affect the chain of reciprocation in between reporting to reported officers / officials. This gets
reflected into the HRMIS (organogram) of the Portal. In lack of a functional e-governance cell within the
region, re-smoothening of the reciprocation chains are being carried out at the Geodata Division.
36
In the year 2013-14, new induction of the DDGs for State Units and Missions and redistribution of
charge, so the chain smoothening been carried out in NER as an extra load on the Geodata. CHQ has
designed new sites into the Portal on creation and posting of the SU and RMH level HAG officers.
Migration of officials from the existed chains, which has become a history, to the newly inducted sites, is
now taking place, using a portal role of administrator at the RHQ (Geodata). The FSP items (Project
mode) for 2012-13 are approved on their links to the sites now become history (Project mode) but the
reports under gone their submission on the carried out work for the seasons have been loading on the
historical sites. Many a times, the post holders at these old sites, are retired, transferred, re-deployed to
other sites and posted to an inducted post for which intervening sites are inducted. This posed a complex
situation, being tackled in perusing cases to CHQ.
B.Portal Phase II:
Infrastructure:
1. Installation of LAN/WAN at SUs: All the State Units of NER, viz. Guwahati, Arunachal Pradesh,
Agartala, Dimapur and Gangtok are connected through intranet using MPLS from BSNL.
2. The service of BSNL (leased line provider for MPLS connectivity) is in utilisation at Guwahati,
Agartala, Itanagar, Gangtok and Shillong. This service has bleak consistency; thereby networks provide
off and on intermittent / frequently disrupted sessions on internet, so the portal access. Comprehensive
AMC of LAN/WAN equipment is awarded to M/s Hue Service Pvt. Ltd, Guwahati.
3. IP phones installed at all locations and video conferencing installed at RHQ.
The table below gives the data of routers, switches and ports to support the Networking in different

Itanagar offices. Video conferencing unit is installed at Dy.D.G office, Shylla building, Shillong. The
bandwidth for the link at Shylla building, Kumud Villa complex and Motinagar office was upgraded from
128 kbps to 1 Mbps now. IP telephones are installed where MLLN link is commissioned and are being
used for inter office communication.
5. GSI portal is accessible through WAN at Shillong (Shylla bldg, Kumud Villa complex and Motinagar
bldg.), Guwahati, Itanagar, Gangtok and Dimapur offices.
6. Connectivity issue/Networking and progress: GSI, Itanagar is under pursuance with BSNL authorities
and CHQ for upgrading the bandwidth for GSI Portal connectivity.
Upgradation of Network 2013:
A project titled “Replacement, upgradation and augmentation of networking devices at different offices of
GSI” has been taken up by CHQ. ‘Nodal Officer’ for each and every independently located LAN were
identified. Devices for replacement/upgradation of existing Network Devices were received through HCL
Comnet and taken into Stock. Installation and temporary configuration attempts were made in Shylla bldg
and Motinagar bldg.
C. Uploading of data and Portal Applications:
1.Uploading of 1:50K maps to GSI Portal: New set of layers after achieving (in FS 2013-14) inter-sheet
feature edge-matching, standardisation of data in stratigraphic fields ( Age, Supergroup, Group,
Formation, Member, Lithology) and assigning a patterned ‘Geometry_id’ values to the spatial extents to
each dimensional size of toposheet as unit have been re-loaded, during the quarter, replacing the place
holding immature layers on Spatial Data Warehouse at CHQ in ‘Map50k Domain’. This is besides the
metadata of the extents have been uploaded in GSI portal.
37
D. Transactional Applications: Transactional Applications on HRMIS, Payroll, FSPMIS and Claims
Modules are operational and are being used by various users in NER.
i) HRMIS: Four new MTS staff was inducted in RHQ, Shillong and their HRMIS data were uploaded
Data of all employees of NER uploaded and is being updated regularly.
ii) FSPMIS: Geodata extended its help to officers of different Projects/Divisions/ State units for
uploading FSP programs and FSP Technical Reports through FSPMIS.
iii) PAYROLL: Pay is being processed through portal at RHQ, Shillong, SU: Guwahati and SU:
Dimapur. Payroll data entered at SU: Agartala.
iv) TOUR and LEAVE: Applications of all officers & employees are being submitted through portal.
v) CLAIMS: RCA/NRCA is being processed by Accounts Sections on portal at RHQ, Shillong. Geodata
helps the Accounts Sections Staff in case of any problem faced by them.
The current usage is limited due to poor or intermittent connectivity and limited awareness about the
usage of transactional modules. Efforts are being made to resolve the problems of intermittent WAN
connectivity and poor services by providing alternate resources.
Other services rendered by Geodata division
Geodata provides software support, scanning on A0 size, other computer related services and
Plotting and printing of documents for the officers of divisions of GSI, NER. Besides, Geodata maintains
the stock registers for the computer hardware and software. Geodata also has a role extended towards
maintenance of hardware and software in the Divisions on AMC.
Geodata extend its service as a collaborator in the training course on GSI Portal applications to the
users in the usage of Transactional modules, conducted by RTI, NER. The division extend its expertise in
acquisition of map data into digital files to the projects of Regional Map & Cartography Division, so the
personnel have been instrumental in capture of 1:50,000 maps generated in process of the drive for
Systematic Geological Mapping and their loading to Spatial Data Warehouse located at CHQ. This digital
dataset is constantly under revision for a better collation, compilation across the toposheet boundaries,
query effective standard values, validated features and authentication of the digital layers to that of
physical maps and replacement of repository at the CHQ based SDW. Geodata Division maintains the
regional repository and versions of revised repository of the dataset.
In the start of a FS year the personnel contact the Regional Geodata for a base map which could help
them to understand geological setup of the area of their field for Thematic Mapping / mineral
investigation / basic data for DRM or similar compositions. The Geodata compose the maps using the
layers exist in the regional repository it has and deliver them promptly.
