摘要
矿区位于西昆仑褶皱带塔木—库斯拉甫铜铅锌成矿带,矿区铜铅矿化主要产于中上古生代拗陷沉积的一套浅变质的海相(海陆交互相)的碳酸岩—碎屑岩建造中,区内构造发育,铅、锌、铜矿化受热液改造作用明显。主要蚀变类型为白云岩化、硅化、碳酸盐化等。成矿背景条件十分有利。初步认为该矿区为层控热液改造型铜铅矿。
The mining area is located in the Tamu-Kuslao copper-lead-zinc metallogenic belt of the West Kunlun fold belt.The copper-lead mineralization in the mining area is mainly produced in a set of shallow metamorphic marine(intercontinental phase)in the Middle-Upper Paleozoic depression.In the construction of carbonate rock-clastic rock,the structure is developed in the area,and the mineralization of lead,zinc and copper is obviously affected by the hydrothermal reformation.The main types of alteration are dolomite,silicification,and carbonation.The metallogenic background conditions are very favorable.It is preliminarily believed that the mining area is a layer-controlled hydrothermal reformed copper-lead mine.
