青海坑得弄舍金多金属矿床地质特征及找矿方向

Geological characteristics of Kengdenongshe gold-bearing polymetallic deposit and prospecting targets,Qinghai

坑得弄舍金多金属矿床位于东昆仑成矿带东端,为近年新发现的金多金属矿床。矿床赋矿围岩为早二叠世布青山群火山岩—碳酸盐岩建造,成矿与晚古生代火山作用关系密切。文章在论述矿床地质特征、物化探异常特征、金及多金属矿化类型的基础上,对矿床成因进行了初步分析,系统地归纳总结了矿床的成矿规律、蚀变特征,建立了坑得弄舍金多金属矿的找矿标志,并结合地质及物、化探资料,指出区域及矿区的找矿方向。

Kangdenongshe gold - bearing polymetallic deposit is located in the east of Dongkunlun polymetallic mineralization zone,is one of the newly discovered gold - polymetallic deposits in recent years. The host rocks are Late Permian Buqingshan Group volcanic rocks - carbonate rocks,mineralization is closely related the late Paleozoie volcanism. It is discussed the geological features, geophysical and geochemical anomalies,gold and polymetallic mineralization types in this paper. The author summarized the law of mineralization and alteration characteristics systematically,whick establishes Kengdenongshe gold polymetallie deposit prospecting marks. With geological and geochemical data objects,the prospecting direction of the region and mining area is pointed out.
