I INTRODUCTION

I 1 GENERAL INFORMATION

The area surveyed is irregularly shaped with its long axis

lying approximately northwest-southeast It is contained within

the rectangle bounded in the north by latitude 18000 I south in

the south by latitude 230 00 south in the westby longitude

129000 east and in the east by longitude 1370 00 east (See

Plate No1 of this report)

One hundred and seventy seven (177) flight lines were

flown one hundred and fifty seven (157) in a direction

approximately northeast-southwest seventeen (17) northsouth

and three (3) approximately northwest-southeast Seventeen

(17) tie lines were flown at right angles to the flight lines

for purposes of magnetic control (For flight line-tie line

diagram seamp Plate No2 of this report)

The initial plan was to use Lockheed Hudson aircraft VH-AGE

carrying the magnetometer detecting head in a towed bird with

navigation and flight path recovery by means of a Marconi 623

Series Doppler but when this aircraft was lost on September 24th

having flown lines 157 to 173 inclusive the Companys Douglas

DC3 aircraft VH-AGU carrying the magnetometer detecting head as

a fixed boomlbull installation was substituted with ~avigation and

flight path recovery by means of one inch to one mile photo mosaics

prepared by Adastra AirWays Pty Ltd

Several lines flown by VH-AGE were reflown by VH-AGU as

repeatability checks between the two magnetometers

All flying was

Northern Territory

carried out from Tennant Creek Aerodrome

middot I 2

Hudson flying operations commenced on 17th August 1966 and

came to an untimely finish when the aircraft crashed on 24th September

1966 DC3 flying operations started on 22nd October 1966 but were

suspended on December 20th owing to continued bad weather DC3 o

operations were recommenced on 13th January 1967 and the survey

completed on 8th June 1967

PURPOSE OF THE SURVEY

The purpose of the survey was to ascertain the depth trends

of major structural features such as faults and magnetic intrusions

and the location of 8JJ1 basin boundaries

The information gained from the survey to be used as a guide

in seleating areas of interest for further more detailed geophysical

surveys in the search for oil bearing struotures

II THE FLYING PROGRAMME

II 1 PRE-FLIGHT PREPARATIONS

As the initial plan was to use Doppler for navigation and

flight path recovery east-west photo strips were prepared from

available 9 inch by 9 inch photography spaced at approximately

twenty-five miles and showing the positions of flight lines and tie

lines These were to serve as a check on the Doppler navigator but

after the loss of VH-AGR complete one inch to one mile mosaic

ooverage was prepared These were used throughout the survey for

navigation and subsequent flight path recovery

II 2 PROGRAMME DETAILS

(a) Survey Altitude

The survey was poundlown at a constant barometric altitude of

2250 feet above mean sea level (amsl) by reference to a

standard aircraft type pressure altimeter with frequent comparisons

against an APN-l radio altimeter

Average terrain clearance was 1250 feet

(b) Flight Lines Flown

One hundred and seventy three (173) poundlight lines were poundlown

the average spacing being two (2) miles Tie lines were flown

perpendicular to the flight lines as sho~ in the flight line shy

III METHODS AND INSTRUMENTS USED FOR THE SURVEY

III 1 AIRBORNE (TarAL FORCE) MAGNETOMampTER

The instrument used for this survey was a Gulf Mark III

total force saturable core fluxgate magnetometer manufactured by

the Gulf Research and Development Company Pittsburgh PennsylVania

The airborne magnetometer is intended primarily for measuring

and recording the Earth 1 s total magnetio field intensity and in

particular looal variations of intensitr such as Dl8yen be oaused by

geologioal inhomogeneities

The equipment oomprises a measuring (deteoting) element an

osoillator to exoite it a vacuum tube oircuit to amplity and deteot

the output variations of the element orientating devices (which keep

the detector element aligned) a potentiometer circuit to compensate

or buckoutlt large changes of field and a recorder

The eqUipment was designed for use in a moving airoraft to

provide a continuous and accurate record of variations of the Earths lt

total magnetic field intensity Beoause an aircratt does not

accurately maintain its orientation in space provision has been made

to hold the measuring or deteoting element in a fixed orientation

(parallel) with respect to the Earths total field

The Earths magnetic field itself is used as a reference the

detector element being aligned with its axis ot sensitivitr parallel

to this field This arrangement places the detector element in the

most favourable position and errors due to improper orientation are

at a minimum Two simUar sets of deteotor elements are used to

sense and seek the position of zero (null) field I

When the axis of sensitivity ot the detector element is aligned

parallel to the Earth t s magnetic field 8DT error in alignment results

in a decrease of the total field reading the magnitude of the error

is proportional to the siDe of the angle ot misorientation and is of

the order ot 05 gamma tor at degree misalignment in a total magnetic

field of 55000 gamma

The value of the step (automatic reset procedure) when

variations of magnetic field exceed the tull scale deflection

(ie 600 gamma) was 500 gamma

III 2 MAGNETOMETER CALIBRATIONS

The instrument was calibrated prior to the survey using

standard Helmholtz coils whose radius and coil constant provided

a force of 10 gamma per 1 milliampere of applied current

(a) Lag Test

Lag or delay of response considered in relation to the ground

position of the aircraft is due to a combination of the following

i) Delay due to electrical resistance in the circuitry

ii) Delay due to meChanical transference ot received signal

to the recorder Chart

iii) Delay due to difference in position between the 35mm film

recording camera and the detector head

To establish this lag it is necessary that the survey aircraft

fly over an easily identifiable magnetic body on a reciprocal course

eg a ship a large metal pipeline an iron bridge etc which will

give a well-defined sharp anomaly Then by identifying the centre

of the disturbing body on the 35mm tracking tilm and plotting its

position on the Chart record the difference between this point

(average of the reciprocal headings) and the peak of the magnetic

anomaly is the total lag for the installation tested

The lag test for this survey was flown owr the Sydney Harbour

Bridge immediately prior to the aircrafts departure

The installation used in this vurvey was checked as described

and no readable lag was detected The side fiducial index pen is

always aligned with the main recording pen

(b) Heading Effect Test

When using the H~son aircraft which towed the magnetometer

there was no heading effect

In the case of DC bull3 aircraft VH-AGU the detector head (measuring

fluxgate~and their respective servo-motors were installed in an

shy extension to the tail section of the survey aircraft

With this type of installation proper compensation for the

asypunetrical distribution of the aircraft IS permanently magnetised

material and the induced magnetic field effects caused by the aircraft

cutting magnetic lines of force on the detecting fluxgate must be made

Compensation for the aircraftls permanent magnetic material m~

be achieved in two ways one by the use of permanently magnetised bar

magnets or two by using induction (air core) coils

Induction coils with variable magnetic intensities controlled

directly by the magnetometer operator are preferable to bar magnets

in that they allow a trial and error compensation pr~cedure to be

carried out whilst airborne whereas in the case of bar magnets fmiddot

adjustments have to be made on the ground

The coil system of compensation was used on this survey tor the

DCbull3 compensation

Variations of induced magnetic fields caused by the aircraft

cutting linea 0 magnetic force on different headings was compensated

- 10 shy

for by the use of high permeabUity strips of metal (IIPermelloyR)

attached to the side af the magnetometer detector head housing

A selected magneticallr quiet area near Tennant Creek was used

for final compensation and a table showing residual heading errors

is included (plate 9) with this report

(c) Repeatability TesectN

I t is required to show that a traverse when poundlown in opposite

directions gives rise to identical (but laterallr reversed)

middot profUes

This test was carried out several times during the survey and

particularly in order to establish repeatabUity between the

magnetometers of VH-AGE and VH~U

III 3 32mm POSITIONING CAMERA

The instrument used to record the position of the aircraft in

relation to the ground was a single frame 35mm c~era using 400 foot

capacity film magazines details of which are as follows

Type Vinten ~5mm Geological Survey Camera

Focal Length 28mm (110 inches)

Shutter Speed l250th sec (set)

Diaphragm Range I f2 - pound32

Format 18mm x 25mm

The camera was mounted in the aircraft with its optical axis

vertical for straight and level poundlight

Exposures were made automaticallr using an electronically

controlled intervalometer set at 30 second intervals With the

exposure interval so set each 35mm frame is overlapped by

approximately 25 - 30 thus ensuring complete ground coverage

-11shy

The camera exposures are related to the magnetic field record

by the use of a fiducial pen on the recorder which operates

simultaneously with the Camera Veeder Counter at every tenth

eleventh and twelfth exposure These fiducials appear on the

right hand side of the magnetometer reqord

Du Pont type 936 Superior Two 35mm fUm rated at 160 ASA was

used throughout the survey

shyAutomatic Film Laboratories Moore Park Sydney processed

the film

III 4 RADIO ALTIMETER

Apart from the pressure (barometric) altimeter which is

standard equipment in all aircraft a radio altimeter type APN-l

was used continuously to record terrain clearance

The instrument was set on IIhigh rangell (0-4000 ft) throughout

the survey and was checked at intervals over the base aerodrome

An Esterline Angus recording potentiometer was used in

conjunction with this instrument to obtain a continuous profile on

a five inch wide curvilinear chart recording at a chart speed of

It inches per minute

III 5 STORM MONITOR (Ground Magnetometer)

During aeromagnetic surveys it is essential that ~ time

variation of the Earths total magnetic field is monitored and

recorded throughout the survey on a 24 hour d~ basis

The normal diurnal change of the Earth I s field which occurs

daily is normally of low gradient and cyclic and is compensated

for in the standard flight linetie line control pattern

_~_______________L______ ___~_)

-12shy

However ~ abnormal variation (field strength varying

erratically over short periods) will affect the recorded results

of all sorties carried out during these periods Where such

variations occur reflying would be necessary

The storm monitor used for this survey was a saturable-core

single fiuxgate magnetometer manufactured by the Gulf Research

and Development Comp~ Pittsburgh Pennsylvania USA

The complete equipment consists of

i) Fluxgate Element (detector head)

ii) Ceramic Spacing Rod

iii) IIBuckoutII magnet

iv) Tripod

v) Esterline Angus Recorder

vi) Compensator

The fluxgate element operates on the same principle as the

airborne instrument ie it comprises two coils having ferroshy

magnetic cores which are driven cyclically through saturation

A secondary (compensating) coil surrounds both primaries

which are connected in series opposition and so arranged that one

core saturates slightly ahead of the other The resultant output

is in the form of sharp pulses when there is no external magnetic

field the positive and negative pulses are equal in amplitude

Should an external field eg the Earth I S normal field be

applied to these cores their times of saturation would be altered c

causing a change in output thus increasing the etfect

To balance or null this introduced external field a current

-13shy

is passed through the secondary coil (surrounding the primaries)

equal and opposite to the disturbing field

It is this current measured amplified and passed through a

potentiometer which is recorded and translated into magnetic units

To obtain maximum sensitivity a permanent magnet (dipole)

supported by a ceramic structure is mounted on the head together

with the detecting element This magnet adjustable in distance

and azimuth from the detector element is used to cancel or IlbuckoutU

the major portion of the Earths normal magnetic field

(a) Record

The recorder chart speed was set at It inches per minute

whilst the aircraft was on survey and It inches per hour at w other times

(b) Calibration

Prior to commencement of the survey the instrument was

calibrated using a standard Helmholtz coil (as used for the airborne

magnetometer)

Full scale deflection over the 4t inch wide recorder chart

was 240 gammas The chart is divided into 50 equal divisions thus

each division has a value of approximately 48 gammas

(c) Storm Monitor

For the period of the survey the sto~ monitor was installed

at Tennant Creek Aerodrome and its operation was continuous

During ~orties the recorder chart speed was It inches per

minute and at othez times It inches per hour

I INTROOOCTlOO

I The area coveredby the survey is approximately 25000

square miles and as far as we know includes considerably

varied geology within these very extensive limits Most of

the area is covered by sand so that our present knowledge of

the geology is based on outcrops which cover only a small

fraction of the total area

The aim of this interpretation is threefold

1 To obtain a general picture of the geology and

especially the distribution of the shallow basement

areas which ~ be used to plan further exploration

within the area

2 ~o find the depth of magnetic basement in areas in

which a considerable thickness of potentially oil ~

bearing sediments ~ exist

3 To recognise certain structures mainly major faults

in the basement which ~ have affected overlying

sedimentary rocks

The very size of the area presents special problems for the

interpreter With so little known about the geology and the

problems not yet clearly defined it is difficult to know which

particular aspects of the interpretation should be emphasised

~le feel therefore that a re-interpretation of the airborne

results at some later date when more is known about the geology

-36shy

of the area will be well worth while

A special problem in this area is the abundance of shallow

magnetic bodies Over almost the entire area there are magnetic

bodies close to the surface Some of these are probably due to

lavas or basic igneous intrustions within the younger sediments

These minor anomalies make itmiddot very difficult

(a) To distinguish between the areas in which a weakly

magnetic basement lies close to the surface and

areas in which non-magnetic sediments with igneous

intrusions are near the surface

(b) To calculate the dept of the magnetic basement

accurately because they distort the shape of the

anomalies associated with the deeper bodies

There is a second interpretation problem namely that in

places the tlbasement ll for oil exploration may not be magnetic

some areas of apparently deep basement may in fact be areas of

very weakly magnetic basement

II METHODS OF STUDyrnG DATA

The major part of the interpretation was carried out by

measuring various parameters of the anomalies using the original

magnetometer records These anomalies were selected from the

magnetic contour map as the ones best suited for depth estimation

using the methods described in Appendix 1 Corrections were

-37shy

made for anomalies which cross the flight lines obliquely

In the course of the interpretation the calculated depths

were related to the pattern of magnetic anomalies seen on the

contour maps and a comparison made with structures and outcrops

shown on the geological maps of the adjacent areas

The numerous small anomalies from near surface bodies

distortthe shape of the anomalies from rocks in the magnetic

basement thus reducing the accuracy of the estimated depths of

basement

The trend of a few of the shallow magnetic bodies can be

followed from line 92 to line 112 If this information is useful

for the appreciation of the geology further interpretation of the

shallow anomalies might be attempted especially in areas where

it is known that conformable lavas or sill occur within the sediments

Until more geological control is available we do not know to which

areas this may be applied

If lavas ar~ found in any part of the area the aeromagnetic

records should be re-examined first to relate the small anomalies

to the lavas and then as suggested above to work out the structure

from them

The most detailed information about the geology of the area

came from two maps provided by American Overseas Petroleum Ltd

Exploration Department One map - D-172-G at 1500000 scale

-38shy

shows all known rock outcrops in the north western part ot the

survey area

Map C118G at 11000000 scale shows the geology as it is

known over the whole area and over a considerable part ot the

surrounding country This map also shows the gravity contours

which are based on surveys carried out by the Bureau ot Mineral

Resources

Information about the surrounding area comes trom the

12534000 scale Tectonic Map ot Australia published by the

Bureau ot Mineral Resources Department ot National Development

Depth contours based on information provided by an aeroshy

magnetic survey tlown by Aero Service Ltd in 1964 are available

in the north western part ot the area

We can summarise the geology as tollowsshy

The oldest rocks in the area are Archean rocks ot the

Arunta Complex These rocks where they outcrop are

strongly magnetic and provide a well defined magnetic

basement they torm much ot the southern limit ot the

sediments in the survey area

Lower and Upper Proterozoic rocks which include

sediments lavas and acid and basic intrusions are tound

on both the southern and northern siQes of the south eastern

part of the area (that is on sheets 5 6 7 and 8 on the

1250000 scale maps) These rocks are 3trongly magnetic

where they outcrop

Most of the outcrops of non-metamorphic rocks seen

within the survey area are of Cambrian age We knoW little

about the structures which affect them

Devonian rocks in OP 123 south east of BarroW Creek

form a syncline Devonian rocks are also found in the

southern part of OP 118 in an areavhere there is a large

negative gravity anomaly

To the north of the area a thin cover of Mesozoic and

Tertiary sediments lie on top of rocks of unknown age

A narrow belt of Tertiary sediments occurs about 20

miles south of Barrow Creek Another thin belt of Tertiary

sediments occurs about 20 miles south east of Devils Marbles

Both narroW belts of Tertiary sedi~nts look as though they

might folloW some eroded major fault line

An airborne magnetic survey was flown over oil prospect 118

by Aero Service Ltd and deptnto basement has been calculated

This was a reconnaissance survey flown for Exoil Company Pty Ltd

with flight lines 8 and 12 miles apart In places we have more

data and can get a little more detail from our interpretation

However the picture of basement configuration is not appreciably

changed

-40shy

A gravity survey was carried out in the BJea by the Bureau

of Mineral Resources which supports this interpretation of the

present aeromagnetic data As we do not know the density of the

various rock groups the interpretation of the gravity results in

quantitative not qualitative The gravity lowsoccur in areas

where the basement according to the magnetic results is deep

Various gravity trends stop abruptly wheregtmagnetic trends indicate

a change in geology

V MAGNETIC INTERPRETATION

The methods used for the interpretation of aeromagnetic data

is described in Appendix I

Examination of the records shows that over much of the area

there are magnetic bodies of at least two depths Some of the

magnetic anomalies are obviously due to weakly magnetic or small

bodies which lie close to the surface These bodies produce a

geologic noise ll through which we can recognise anomalies from

a much deeper source which we consider constitutes the magnetic

basement in this area Several thin linear magnetic bodies near

the surface can be followed for twenty miles from line to line

they are probably lava flows or sill but may be dykes

The survey consists of one large area described in two parts

for which the basement geology is different There are also eight

blocks of four lines which were flown over better exposed areas

on the periphery of the main sand covered area and three blocks

of lines flown over Oambrian rocks at the eastern end of oP 123

These blocks have been described separately

In the eastern part of the main area the anomalies are

strong and trend west-northwest In the western area the

anomalies are weaker and the trends more variable The

boundary between the two areas which runs across from sheet

12 to sheet 13 and across sheet 15 is in the Pre-Cambrian

rocks and not necessarily an important one in the Palaeozoic

rocks bull

Eastern Area

The blocks of lines are marked A B C and D on the

interpretation map These areas are described first and will

then be referred to occasionally in the description of the main

area These areas differ from the main area in the amount of

geological information available They provide a calibration

for the interpretation by showing the type of magnetic response

which may be expected from a number of the rock groups

Block A

The geology in this area consists mainly of Middle Protershy

ozoic rocks (Hatches Creek Group) and some Cambrian rocks The

rocks are folded along axes which strike north-west or northshy

northwest and are cut by faults which strike north-south and

north-west

The anomalies in the area have a high amplitude ard obviously

lie very close to the surface The southwest~rn part of the

block on sheet 17 is very strongly magnetic the part of the

-42shy

block on sheet 18 is less magnetic The boundary between them

which is shown on the interpretation map appears to strike

northwest and is possibly a fault There appears to be a

second boundary between Block A and the main area this boundary

also appears to strike northwest The Middle Proterozoic rocks

in this area would constitute a magnetic basement if they occur

beneath less magnetic sedimentary rocks

At the northeast end of the lines where the Cambrian rocks

outcrop the basement is about 2500 feet below sea levelbull

Block B

Block B consists of three bands of lines Bl B2 and B3

Huch of the area is covered by sand Cambrian rocks outcrop

along the southeastern edge

The magnetic anomalies in this area strike east-west and

southwest and have a high amplitude In the northwestern part

of the block the magnetic basement is less than 1000 feet bel~w

below sea level it also appears to be shallow in the southeastern

corner Between these two areas there lies a basin I in which

the magnetic basement is about 4000 feet deep This basin

extends southwest outside the limit of Block B and it also

extends to the north east across a shallower part There are

two major faults in the basement rocks One crosses B3 and

strikes east-northeast This fault appears to be a continuation of

a large fault seen near the southern end of the main area (sheet 20)

-43shy

The northern limit of the sedimentary basin in Block B

might also be related to an extension of a large east-northeast

fault in the main area (sheet 25) but if it is it is not evident

on the magnetic map The boundary between the basin and the

shallow magnetic area in the southeast corner of Block B also

appears to be a fault which strikes northeast This suggests

that the deeper sediments in this area occur in a trough-like

Block C

Upper Proterozoic rocks outcrop in the northern part of

Block C and Archaean rocks of the Arunta Complex outcrop in the

I The anomalies over the Upper Proterozoic rocks are large

and tta magnetic bodies are obviously very shallow or actually

reach the surface The anomalies are presumably due to basic

rocks In the southern part the rocks are less magnetic but

are still shallow This is quite consistent with what is known

about the geology

The strike of the magnetic anomalies in the southern part

of the area is east-west in contrast to the northwest strike

which is seen in the northern part This indicates adifference

in the structural pattern of the two parts of the block The

boundary between the main block and Block C strikes northwest and

from the sharp change we think that it may be a large fault

-44shy

Block D

The rocks exposed in Block D consist of Upper Proterozoic

in the north and Archaean rocks in the ArunJa Complex in the

south A narrow band of Tertiary sediments which strikes

northwest runs across the area and coincides with the steep

gravity gradient The geological map shows shear zones in the

north An inlier of Cambrian rocks occurs near this Block

The magnetic basement is shallow on sheet 20 where the

upper Proterozoic rocks outcrop The well developed gravity

minimum coincides with areas in which the magnetic basement

reaches a depth of 3000 feet This suggests that there is a

basin II within the Upper Proterozoic rocks and faulted with

either weakly magnetic Proterozoic or younger rocks possibly

bounded on its northern side by a fault~

A basement depth of 1700 feet southeast~f Barrow Creek

seems to occur over Proterozoic rocks and not over the Cambrian

outlier This apparent depth found over weakly magnetic rocks

may ~ccount for a number of conflicting depths observed elsewhere

in the area

Main Area

The rocks which outcrop in this area include one which range

in age from Archaean to Devonian Except for the major basin

implied by the outcrops of Pre-Cambrian to the north and south

of the Lower Palaeozoic rocks in the middle of the area there

are no major structures to be seen The Devonian rocks occur

with the fold which strikes northwest There are few outcrops

-45shy

within the area which is almost entirely covered by sand The

southern boundary of the area lies close to the most northerly

outcrops of the Arunta Complex

A gravitY survey was carried out in this area by the BMR

and two extensive negative anomalies indicate areas in which there

m~ be greater thicknesses of light sediments

Both gravitY and magnetic maps indicate three areas in which

sediments ~ be thicker than elsewhere One area lies 50 miles

east of Barrow Creek the second lies along the southern ~dge of

OP 118 and OP 119 the third area lies in the southeast corner

of OP 120

(a) Depth of Basement

In the northern part of the area the depth determinations

made on the magnetic anomalies indicate that the basement is shallow

most of it being less than 2000 feet below sealevel and some of it

being less than 1000 feet On sheet 20 (south west corner of

sheet 6) the limit of this area of shallow magnetic basement seems

to be a fault which strikes northwest or west-northwest and

separates the shallow basement area from the deeper basin 111

which lies in the south west corner of 0P123 This basin is

4000 feet and 5000 feet deep Magnetic bodies at shallower

depths in the centre of the basin may be due either to anuplifted

block to an intrusion or to a mass of lavas within the basin

A small basin IVIt which lies 15 miles southwest of the end

of Block A is possib~ due to a small basin of Cambrian or nonshy

magnetic Middle Proterozoic rocks

-46shy

A large magnetic structure which strikes west-northwest

is associated with the northern margin of the basin V which

lies on the southern edge of 0Pll9and OPllS and for the most

part coincides with the large negative gravity anomaly This

basin is about 4000 feet deep at its eastern end and is about

10000 feet deep in the middle

The shallower depths on sheet 15 correspond to relatively

higher gravity values within the gravity low already mentioned

To the west of this a greater depth m~ be associated with a

transverse fault which runs north-northeast this structure

could affect the distribution of oil or gas in this area

At the western end of the basin a west north west trending

anomaly within the basin gives unusually shallow depths flanked

by much deeper values This magnetic boQy presents a puzzle~

It is very narrow for a horst block but on the other hand it is

unusual to have a wide Qyke in this position~ It is possible

that the deep values to the north of this block come from a

weakly magnetic basement We can only draw attention to this

boQy and remark that there is some peculiarity in the geology

It ~ justify fUrther ground investigation This shallow

structure and the main basin gtoth end against a large northshy

northeast fault

The southern limit of this basin V is the outcrop of the

Arunta Complex which is distinguishable on the magnetic records

by the abundance of shallow anomalies The boundary is abrupt

and may be a fault There are a number of III1ch shallower values

found within the area and it is difficult to interpret them

-47shy

They m~ be due either to local shallowing of the basin floor

or to magnetic bodies within the sediments

In the northern part of the area (on sheet 17 northwest

corner of sheet 6) several shallow anomalies can be followed from

line 92 to line 112 This suggests that the shallow anomalies

here are due to a bedded magnetic horizon or to qykes Because

volcanic rocks are found within the Cambrian rocks in 0P152

these magnetic anomalies maT be due to lava flows or volcanic

ash Similar shallow magnetic bodies occur in profusion over

most of the area

Area VI to the south of those bedded magnetic rocks

referred to above (close to the western edge of sheets 17 and 20)

there are a number of shallow depth determinations in the middle

of deeper values We think these shallower values are due to

intrusions or volcanio rocks which lie olose to the surface

Between this area and the basin VII in OP 123 there aPpears to

be an area in which magnetic rocks are abundant at shallow depths

This coincides wi~h an increase in the gravity field and thus

likely to be an area in which the sediments are thin

Elsewher~ in the eastern area the cover of weakly magnetic

rooks is not thick

(b) Structure

The magnetic anomalies within this area run mainly northwest

and southeast with an occasional swing in the strike to east-westbullbull

Some information about the main structural divisions of the

-48shy

basement rocks can be obtained from the pattern of the magnetic

anomalies which indicate a number of major changes within the

Pre-Cambrian rocks There appear to be major fault zones striking

east-northeast near basin III judging from the depth estimation

made from the magnetic data some of these faults have moved since

the Palaeozoic sediments were deposited in this area Most of

these faults have a very considerable strike length One fault

which cuts across the area near point 136 E and 210 45 S m~ extend

to Block B as described earlierand may form the northern edge of

one of the areas of deeper sedimentation 111 bull

The southern boundary of the main outcrop of Lower Proterozoic

rocks in OP 123 also follows a well-defined magnet~c feature in

the basement rocks

There are some north-south trends VIII on the magnetic map

which we think ~ be associated with faultsbut it is difficult

to make out the direction of movement of these faults or whether

they have been moved since the sediments were deposited (In other

areas there is an obvious change in the thickness ot sedimentson

either side of the big faults)

The Basin IlIon sheet 20 is cut by one of these north-south

faults and there are several anomalies superimposed upon the larger

ones which couldcome from igneous rocks whichmiddothavebeen intrudedmiddot

along the fault plane

On the eastern side of sheet 16 a break in the magnetic

pattern suggests that a large north-northeast fault IX cuts across

this area The shallow anomalies which were picked out on lines

92 and 112 stop on the line ot this fault This suggests that the

-49shy

fault affects both the basement and the sediments

On the southern side of the area on sheet 20 the change

from basement (Archaean rocks) to non-magnetic sediments is

abrupt Anomalie s here are superimposed on one very large

anomaly whose source appears to lie 12000 feet below sea level

and is very well seen on flight line llJ It is possible that

this deep feature controls the boundary of the Archaean rocks

both here and to the west where the rapid change in depths as

determined from the magnetic map suggests a large fault bull

The northern edge of the basin is complex We think that

it is bounded bY a fault which is marked both by its strong

magnetic trends and by the change in depths indicated by the

magnetic anomalies

The western end of basin V is a large north-northeast fault

which m~ extend to basin XII The actual division between the

eastern and western part of the area is not a clear cut line

The boundary includes a zone in which much shallower but more

erratic basement depths are observed

Western Area

The western area has a completely different magnetic pattern

from that of the east Unlike the pronounced linear pattern in

the east the anomalies in this area have no well-defined trend

direction

Most of it is covered by sand through which occasional outshy

crops of Cambrian rock are seen At the extreme western end of

the area Upper Proterozoic rocks outcrop The only structures

-50shy

indicated in this area are faults which strike northwest there

is no indication of folding in the Palaeozoic rocks

In the western part of the area the flight lines were

flown in bands so that the info~mation about part of this area

is less complete than it is in the east and the results should

treated as reconnaissance survey findings only

For convenience we could describe the blocks separate~

Blocks E F and G lie to the north of the area Block H lies at

the western end of the area

Block E

This block or l~nes covers outcrops of Lower Proterozoic

rocks in the north to Cambrian rocks in the south Magnetic

rocks are shallow in the north and are presumably Proterozoic

The boundary of the shallow rocks is abrupt and is possibly a -

fault Depths of 5000 feet are found to the south and mark

the beginning of a basin X which extends to the west We do

not know how far this basin may extend tothe east To the

southeast the basement is less than 1000 feet below sea level

Block F

Shallow magnetic rocks are found on the nor~hern part of

Block F and are separated by a well defined boundary from

deeper magnetic basement in the south This boundary m~ be a

continuation of the one seen on Block E The basin of weakly

magnetic rocks is 5000 feet deep

-51shy

Block G

The rocks which outcrop are of Cambrian age In the

northern part of this strip the depth estimates vary considerably

and it is difficult to know whether we are dealing with a

sedimentary seotion containing magnetic rocks or a weakly magnetshy

ised basement The anomalies which run along the direction of

the flight lines could indicate a shallow basement In the

south the more consistent values indicate depths ot 4000 teet

and ~ mark the continuation ot the basin X seen in Blocks E

Main Area

Within the main area east of block F (on sheet 13) we

show a small basement high on the interpretation map which is

based on three value s only As there are a number ot shallow

anomalies in the area probably due to magneticJqers within

sediments we cannot be quite sure that these three values are

in fact trom the basement If they are due to other larger

magnetic masses within the sediments then the shallow basement

which divides basin X disappears and we can take the basin through

trom Strip E to Strip F This basin deepens to about 7000 teet

and widens towards the west and ends at a basement ridge XI which

runs north-northeast

There is probably one basin XII about 7000 teet deep on

the western side ot this ridge but as it lies in that part of the

area where the aeromagnetic cover is not complete we cannot be

sure about the probable north-south strike or continuity ot the

~ t i -~

-52shy

of the basin The eastern edge of the basin lies on the line

of the large north-northeast fault postulated at the western

end of Basin V There is no evidence for a continuation of

this fault on the aeromagnetic lines flown but this may be due

to the combination of flight path direction line spacing and

unfavourable basement geology

In the north western part of the area there is another

basin XIII which is separated from XII by a ridge This basin

is about 10000 feet deep The survey has not been extended

far enough to indicate the northern limits of this basin

Block H

Block H lies on Sheets 5 and 10 and has been flown almost

entirely over Upper Proterozoic rocks in which northwest faults

are seen The southeastern part ofthe stripis magnetically

flat and the contours run parallel to the flight lines so

that we obtain satisfactory depth values from the records bull

On the margin of Sheets 10 and 6 the magnetic basement is

obviously very shallow At the northwestern end of the blOck

shallow values indicate the outcrop ping of magnetic basement

Between these two groups of shallow anomalies the smooth contours

indicate a considerably deeper magnetic basement it is not

possible to make a proper depth estimate because of the numerous

small shallow magnetic bodies which distort the curve The

shallow values determined from the magnetic survey correspond to

areas in which the gravity values are high and the broad anomaly

which would indicate a basin corresponds to a gravity low

SUHMARY AND RECOMr-tENDATIONS

The results o~ the interpretation are most clearly

~arised on the 11250000 interpretation maps All sheet

numbers quoted in the text refer to the 100000 sheet layout

The major basins correspond closely to those indicated

by previous aeromagnetic surveys gravity surveys and the geology

~~ar basement faults striking east-northeast and north-northeast

are shown on the interpretation maps these faults may produce

minor folds or faults in the overlying sediments which could

affect the distribution of hydrocarbons in the area

Most of the ground surveys should be carried out in the

area where the basins occur We also suggest that particular

attention be paid to the origin of the shallow anomalies in all

areas If these anomalies are due to magnetic sediments the

magnetic map could yield an immense amount of structural informshy

ation the magnetic properties of the ~ediments pound-rom drill core~

should be studied especially if they-are found in an area in

which there are no igneous rocks to account for the anomalies

If igneous rocks occur the magnetic susceptibility of samples

should be measured so that the anomlies can be fully accounted

for the pattern of dykes and sills in an area might throw some

light on the structures If volcanic ashes are a potential

reservoir rock the changes in the magnetic anomalies may take

on a new significance

APPENDIX I

METHODS USED IN THE INTERPRETATlm OF THE

AEROMAGNETIC DATA

Harf-Slope Method

The measurements required for the Half-5lope method were

taken directly from the magnetometer profUe charts

The distance between the tangential points of contact of the

anomaly curve and the line of half maxinum slope have been empiricallJr

related by Peters to the depth of a dyke-like body so orientated

with respect to the Earths magnetic field that it produces a

symmetrical anom~ the distance between the inflection points or

points of maxinum slope is related to the maximum horizontal width

of the body This ratio of width to depth varies from anomaly to

anomaly and partially controls the choice of empirical factors used shy

in depth determinations the application of an appropriate factor

converts the scale distance between Half-Slope contact points into

a depth below the aircraft Where the anomaly is not quite symmetrical

the two flanks of an anomaly are processed independently and the results

averaged

This method could be in severe error if applied to anomalies

which are too disturbed too asymmetrical too comp1lex or not dyke-like

therefore care has to be taken in the selection of suitable anomalies

The method presents a number of advantages however mainly speed and

ease of use but especially its applicability to slightly disturbed

or complex anomalies which do Dot JustifY more elaborate analytical

techniques

The depth obtained by this method is plotted midway between

the two inflection points of the anomalJr one or both flanks of

some very wide anomalies are treated separatel1 1n these cases

the depths are plotted at the 1ntleotion points on the assumption

that they represent the depth of the ~vidual contacts

A modification of this method which is more frequently used

permits the ~dth of the anomalous body to be calculated and makes

allowance for anomalies which are not symmetrical More accurate

depths may be calculated in this way than can be achieved by the use

of the simple half-slope method

Dipping Dyke Method

The Dipping Dyke method was developed by personnel of Huntec

Limited of Toronto Canada Although a paper is in preparation whichdescribes its application it is at present unpublished

Utilising the position of the inflection points the gradient

at these points and the maximum magnetic field value on a profile

at right-angles to the strike of the body information on depth width

dip location and magnetic susceptibility contrast is obtained with

the aid of prepared charts and tables

Under certain conditions this method may give reasonable

answers from anomalies which are not caused by dyke-like bodies

However specific checks such as the shape of the anomalJr are provided

by the method and help in detecting these cases If this method does

not function on a given anomalT it is an indication that the anomaly

-56shy

is not derived from a Qyke-like boQy or that it is distorted by

anomalies from adjacent bodies An undetected or misinterpreted

regional gradient could also prevent its 8pp+ication

Depths obtained using this method are plotted onto Total

Magnetic Intensity contour maps at the calculated centre of the

dyke-like boQy

Characteristic Curve Method

This method resolves basically into matching the field anomaly

to a suitable theoretical anomaly derived from the mathematical

expression for the induced external magnetic field of the chosen model

by the use of co~ted characteristic curves

A comprehensive series of such curves has been prepared for

use with total magnetic -intensity measurements by Computer Applications

and Systems Engineering of Toronto Canada the curves have been

derived for various models which have geol~gical eqUivalants ie

tabular bodies dipping dykes vertical prisms stepcontacts horizontal

plates and rods

Several parameters of the theoretical anomaly are measureq and

combined to produce dimensionless quantities the most diagnostic

combinations are then chosen as estimators and plotted against the

parameters in families of characteristic curves

The interpretation involves measuring the most diagnostic

parameters on the magnetometer field record or contour sheet from

the estimators so produced it is possible with the characteristic

curves to interpolate the characteristics of the causative boQy

The results of the analyses are converted into map scale units bT the

-57shy

comparison of suitable linear parameters the choice ot parameter

being dependant on the chosen model A poundUrther set at curves enables the magnetic susceptibility contrast to be determined

Half-Width Method

Using this method a number at parameters can be measured on a

wide range of theoretical dyke curves and the results presented as a

series at curves which relate these parameters to the depth at the

causative body The distances measured include bull

(a) The distance separating the maxillllDl and minimum

gamma values of the anomaly

(b) The horizontal extent of the anomaly at half the

maxillllm amplitude

(c) The distanc-e separating tpe points of quarter and

three quarters at the maxiJJlllll amplitude on each

flank at the anomalybull
