Abstract:
BecausehistoricalgeologicalexplorationworkandavailableresearchonEukabylead-zincexplorationarefew,previous prospectingworkhasnotmadeagreatbreakthrough.Inordertoobtainpreliminaryevaluationofprospectingpotentialintheexploration area,soilgeochemicalsurveys(ascaleat1:10000)havebeencarriedout.AccordingtothesoilgeochemicalsurveysinEukaby,the methods of factor analysis, correlation analysis, and cluster analysis from mathematical statistics were applied to investigate the characteristicsofelementcombinationinthisarea.Elementanomaliesweredelineatedbythresholdvaluesofsoilanalysiselements. Thedistributionofelementanomalieswasfoundtobecontrolledbythewelldevelopedjointsandfractures.Themetallogenicmaterials werederivedfromthecontinentalweatheringproductsandwallrocks.AlsotheDelamerianorogenyandsubsequenttectonicactivities providedtheconditionofore-bearingspaceandheatsourceforremobilization,enrichment,andprecipitationofmetalelements.Basedontheanalysisofregionalgeologiccharacteristics,threegeochemicallycomprehensiveanomalousareasweredelineatedinthesoil geochemicalsurveyarea,whichwouldprovidethebasisforfutureexplorationwork.
