藏北安多县抱布德铅多金属矿床地质特征及找矿方向

抱布德铅多金属矿产于硅质岩、灰岩中,围岩主要为灰岩、少量泥岩,蚀变普遍,构造发育。通过野外地质工作,结合已有资料,从区域地质特征及构造演化成矿方面对抱布德铅多金属矿床进行分析,初步分析矿床与区域构造运动、广泛发育的NW向断裂、三叠纪地层有关,矿区断裂构造、硅质岩为以后探矿的重点区域。

Geological Characteritics and Exploration Direction of Baobude Plumbum and Polymetallic Deposit in Anduo County of Northern Tibet

Baobude plumbum and polymetallic deposit occurred in siliceous rocks and limestone. Its country rocks are mainly composed of limestone and small amount of mudstone. Alteration is general and structures developed well. In this paper, through field geological work, combing with the former information, from the aspect of regional geological characteristics and structure evolution, Baobude plumbum and polymetallic deposit has been analyzed. It is indicated that the deposit has close relation with regional tectonic movements, well developed faults with the trend of NW and Triassic strata. The faults and siliceous rocks are important ore prospecting areas in the future.
