DISCOVERY OF THE QINGSHUIQUAN Cu-Ag-Pt-Pa PRECIOUS METAL DEPOSIT IN XINJIANG AND EFFECTIVENESS OF ITS GEOCHEMICAL EXPLORATION

On the basis of 1∶500000 regional geochemical exploration transverse, in combination with the geochemical characteristics of the landscape, the Hs-19 No. anomaly area was selected for 1∶1000000 stream sediment and 1∶100000 rock reconnaissance, followed by the affirmation by geological engineering work. Finally the target area of the Qingshuiquan Cu-Au-Pt-Pa deposit was defined. Geological practice in the exploration of Cu-Au-Pt-Pa deposits in the Altai region of Xinjiang has shown that to stress the importance of selecting regionally geochemical exploration anomaly areas, conduct systematic anomaly investigations, and carry out geological tracing and engineering disclosing of the optimal anomaly areas is able to effectively reduce the time period of geological exploration and save the funds for geochemical exploration.
