西藏索县沙仁嘎铅锌矿地质特征及找矿远景分析

摘要

西藏索县沙仁嘎铅锌矿产于上三叠统夺盖拉组地层中.目前已发现的4个矿(化)带呈透镜状、脉状、似层状产出,且受矿区近东西向和北北西向的断层控制.矿石组合为铅+锌+银,矿石构造以网脉状和块状集合体为主.通过对矿区地质、矿体及矿石特征分析后,认为该矿床主要受地层、构造因素控制,且具有良好的找矿远景.%The Sharenga lead-zinc deposit in Sokshan, Tibet is hosted in the shale, sandstone and marl of Upper Triassic Duogaila formation. The four mineralized belts occur in lenticular, veined and stratoid shapes, controlled by near east-west and NNW-trending faults. The ore contains Zn, Pb and Ag, mainly in stockwork and massive structures. Based on the analysis of geology in the orefield, features of orebodies and ore, it is believed that the deposit is controlled by the strata and structures, with good ore-searching prospect.
