内蒙古李清地铅锌银矿床地质特征及找矿标志

Geological characteristics and prospecting criteria of Liqingdi lead-zinc-silver deposit,Inner Mongolia

李清地铅锌银矿位于华北地台北缘、内蒙古台隆之东段,临河—集宁—尚义深大断裂带南侧,阳高—大同弧形深大断裂北侧。矿区及其周边分别多个小型铅锌银多金属矿,通过对矿区地质特征、物化探异常、矿石矿物及工程验证综合研究,总结矿床成因,提出找矿思路及找矿标志。同时将矿区的物化探异常特征、蚀变类型、矿物组合,矿物来源等与典型的浅成低温热液型矿床相对比,提出该矿床深部的潜力,值得进一步进行勘查研究。

Li Qingdi lead-zinc-silver deposit is located 0 n the northern margin North China plat,the eastern section of the Inner Mongolian rise and the south side of the Linhe-Jining-Shangyi deep fault zone,and the north side of the Yanggao-Datong arc-shaped deep fault.There are several small lead-zinc-silver polymetallic deposits in the area and its surrounding areas.The article summarizes the genesis of the deposits through the geological characteristics of the deposit,geophysical and geochemical anomalies,ore minerals,and proposes prospecting strategy and prospecting criteria.Meanwhile the geochemical geochemical anomaly characteristics,alteration type,mineral combination and mineral source of the mining area are compared with typical epithermal deposits,and concluded thatthe potential of the deep part of the depositis worthy of further investigation.
