东昆仑鄂拉山地区银铅锌多金属矿床成矿时代及成矿模式研究

Metallogenic age and metallogenic model of silver lead zinc polymetallic deposits in the Hubei mountain area of Eastern Kunlun

鄂拉山口地区地处东昆仑、西秦岭、南祁连造山带交汇部位,内部结构复杂。晚三叠世在北西—南东向挤压应力场作用下,形成了鄂拉山口地区一系列与火山机制有关的银铅锌多金属矿床。本文针对拉山口地区银铅锌多金属矿床成矿时代及成矿模式进行了相关探讨,为该地区进一步深度找矿提供相应的理论借鉴。

The area of ora Yamaguchi is located in the intersection of East Kunlun,West Qinling Mountains and southern Qilian orogenic belt,and its internal structure is complex.Three late Triassic in NW se trending compressional stress field,forming a elashankou area and a series of volcano on the mechanisms of silver lead zinc polymetallic deposit.This paper discusses the metallogenic epoch and metallogenic model of silver lead zinc polymetallic deposit in La Shan pass area,so as to provide theoretical reference for further deep prospecting in this area.
