of doleritedykesandvariationsin thetopographyof theupperand

lowersurfacesof thebasalts. Pronouncedminimaon themagnetic

traverses,suchas occurson traverseA nearthemiddle,shownin

figure2, canbe confidentlyascribedto a faultin thebasalts

downthrowingto thenorth. Pronouncedmaxima,suchas occurin the

middleof thenorthernhalfof traverseA canbe interpretedeitheras

a dykeor as a faultdownthrowingthebasaltsto the south. It is

difficultto decidebetweenthesetwomodelsif the anomalyis over-

lappedby otheranomalies.Howevercontrolis availablein the

formof gravitydatafrompreviousworkon traversesA and G and this

has allowedus to distinguishbetweenfaultsanddykeson thesetraverses

and the resultshave thenbeenextrapolatedon to the othertraverses.

Somemeasureof controlis providedat theeasternsideby outcropsalong

the escarpment.We havenot beenableto carryout quantitative

interpretationsof the majorityof anomaliesbecausetheyfrequently

overlapeachotherand thusthe fullanomalycannotbe recognised.

However,we do not considerthisa seriousdeficiencyas a qualitative

interpretationof the datahas allowedus to deducethe structureof the

area.

We havebeen ableto correlateourdatawith themagneticdata

previouslyobtainedalongtraverses1 and 3, correspondingto traverses

A and G of thissurvey. The correlationsare shownin figure9 and

10 and correlationcoefficientswere0.95and0.97respectively.

Featurescan be correlatedbetweenadjacenttraversesof our survey

as can be seenfromthemagneticprofilemap, figure11. Somefeatures

suchas theminimaoccurringnearthecentreof the area,can be

correlatedover theentireeast-westextentof the areawhilstothers,

suchas in the south-eastof theareacanonlybe correlatedoververy

shortdistances.Thisconfirmstheconclusionsof our 1980reportwhich

suggestedthepresenceof a few large,persistentfeaturesparalleled

by numerous,smallimpersistentfeatures.

We have interpretedthemagneticprofilemap to producea picture

of the geologicalstructureof thewellfieldarea,figure12. The

As opposedto thesimplestructurein thecentralpartof thearea,

We considerthatdykesarelesscommonin theareathanhadpreviously

Theabsenceof dykesin thecentralpartof theareaandthecomparative

ourinterpretationof themajorityof themagneticanomaliesas faults

it is knownthatwaterqualitywithinthisformationis variableand can

This is located2 km to the southof the Palapye- Seroweroadand

liesSOOmto thewestof the sandstoneoutcrop. It is positionedto the

northof a westnorthwest- eastsoutheasttrendingdoleritedykewhich

is visibleon aerialphotographs.The exactlocationof the dykeon the

The siteis locatedon the northflankof thedykewith theobjectof

interceptingany fracturezonethatmay be associatedwith thedyke

emplacement.To the southof thedykethe resourceis alreadycommanded

by 4 existingboreholes(Fig16).

The boreholeis to be drilledto a depthof between120 - 150m since

APPENDIX

TheGroundMagneticsSurvey

The surveywas carriedout between10thand 29thNovember1981.

It consistedof 13 lines,approximately7000m long,orientated111°east

of gridnorth. Anotherline,9275m long,and orientatedalmost

east-westlinkedthe southernendsof the lines. Originallya linelinking

thenorthernendsof the lineshad beenplannedbut thiswas not carried

out due to lackof timeas the surveywasdelayedby a bushfire. Lines

A and G of our surveycorrespondto traverses1 and 3 of a previous

exploratorygeophysicalsurvey.

The bushwas clearedalongthelinesand the stationsmarkedby

. woodenpegsat 25m intervals.Thisstationspacingwas chosenon the

basisof previousmagneticsurveyscarriedout in thearea. The spacing

is smallenoughto definethemagneticanomaliesfor a quantified

interpretationto be madeyet largeenoughfor the surveyto be carried

out in a reasonabletime. The stationswerenot levelledin as elevation

correctionsare notusuallymade to magneticdata.

A GeometricsG.826portableprotonmagnetometerhavinga 1 gamma

sensitivityand repeatability,was usedfor the fieldsurvey. Diurnal

variationsin the geomagneticfieldweremonitoredusinga Geometrics

G-826Abasestationprotonmagnetometerwhichwas sitednear the centreof

the southernbase line. This instrumenthas a sensitivityand repeatability

of 1 gammaand readingswererecordedat 1 minuteintervals.Duringthe •

periodof the surveythegeomagneticfieldvariedby 70 gammas,however,

thedailyvariationwas usuallyabout10 gammasover 6 hours. Exceptions

to thisoccurredon 14thand 25thNovember.On the latteroccasion

the fieldfluctuatedby 40 gammasovera periodof 30 minuteson several

occasions.

The fielddatawas correctedfordiurnalvariationsin the

geomagneticfieldby a computerprogramwhichfitteda cubicsplineto

thebasestationdatafor interpolationand thencorrectedthe fielddata

relativeto a datumof 30630gammas. A listingof the correcteddata is

givenat theend of thisappendix.The computerprogramalsoplotted

the correcteddataon a graphplotterto producefigures2 to 11 inclusive

of thisreport. In additionthcpowerspectrumof each traversewas

calculatedand thecrosscorrelationfunctionsbetween.traversesA and

and traverses1 and 3 respectivelyfromthepreviousgeophysicalsurvey.
