新疆清水泉铜金铂钯贵金属矿床的发现及其地球化学找矿效果

在1∶500000区域化探扫面的基础上,结合景观地球化学特征,筛选出Hs 19号异常,进行1∶100000水系沉积物及1∶10000岩石测量,再经地质工程验证,最终圈定了清水泉铜金铂钯矿床。新疆阿尔金地区铜金铂钯贵金属找矿的实践证明,重视区域化探异常的筛选,进行系统的异常查证,选择最佳异常区进行地质追踪和工程揭露等,能有效缩短勘查周期及节省勘查资金。

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.
