摘　　要：西天山地区构造活动强裂,中酸性侵入岩发育,化探异常普遍存在,找矿标志信息丰富,是世界级金、铜等矿产的富集区。20世纪60年代以来,前人先后在该地区进行过1∶100万地质调查和1∶20万、1∶5万区域地质调查等工作,发现较多铜矿点。此次化探工作在1∶10万化探普查圈出的“14乙”综合异常基础上,通过1∶2万岩屑测量,圈出单元素异常341个,综合异常11个,提出地球化学找矿标志,缩小了找矿靶区,初步圈出金矿体11个,为一个特大型金铜矿的发现夯实了基础。The West Tianshan area is a rich area of gold,copper and other minerals in the world,due to its active tectonic movement and strong fractures,the development of intermediate-acid intrusive rocks,the widespread existence of geochemical anomalies and abundant information of prospecting indications.Since the 1960s,predecessors have carried out 1∶1 million geological survey,1∶200000 regional geological survey and 1∶50000 regional geological survey in this area,and many copper ore spots have been found.Based on the 14B comprehensive anomaly delineated by the 1∶100000 geochemical survey,341 single element anomalies and 11 comprehensive anomalies have been delineated through the 1∶20000 lithic debris survey.The geochemical prospecting markers have been put forward,the prospecting target area has been narrowed,and 11 gold orebodies have been delineated preliminarily,laying a solid foundation for the discovery of a large gold-copper deposit.
