适用于东天山地区的区域化探工作方法与找矿效果——以新疆哈密市清白山铅锌矿为例

在新疆哈密市磁海铁矿一带开展的1∶25万区域化探数据更新工作,采用新的采样布局、采样方法和样品加工方法,在取得真实可靠的区域地球化学资料的同时,圈定了钨、钼、铅、锌、金、银等一批有找矿前景的异常.根据区域地球化学成果,在良好的成矿条件基础上,重新认识了该区成矿地质背景,确定主攻方向并开展异常查证工作,取得了良好的地球化学找矿效果,尤其是在北山成矿带发现的清白山铅锌矿,开拓了北山成矿带的找矿空间.

The result of applying the regional geochemical method to the East Tianshan Mountains: A case study of the Qingbaishan lead-zinc deposit in Hami area

A new sampling layout and samples processing method was applied in the updating work of 1 ∶ 250 000 regional geochemical data in Hami-Cihai iron deposit in Xinjiang.A number of anomalies of such elements as tungsten,molybdenum,zinc,gold,and silver were delineated and the detailed regional geochemical data were obtained.According to the regional geochemical survey,the metallogenie geological background was re-recognized based on the favorable metallogenic conditions.The authors have obtained some prospecting achievements,especially the discovery of Qingbaishan lead-zinc deposit in the Beishan metallogenic belt.The results obtained by the authors have broadened the exploration space of the Beishan metallogenic belt.
