新疆若羌县维宝铅锌矿床地质特征及成因分析

Geological characteristics and genesis of the Weibao Pb-Zn deposit in Ruoqiang County,Xinjiang

维宝铅锌矿床位于祁漫塔格成矿带西段,矿床产于元古界蓟县系狼牙山组浅海相碎屑—碳酸盐岩系地层中,矿体具有明显的层控性,以及多阶段矿化特点。文章在深入分析矿床地质特征及成因的基础上,提出了该矿床在成因上属后生层控多金属矿床,并总结了找矿标志,认为在东昆仑—祁漫塔格地区具有较大的找矿前景。

The Weibao Pb-Zn deposit located in western part of Qimantage metallogenic belt, and occurred in the strata of neritic facies clastic rocks--carbonate rocks series of Langyashan Formation in Ji County System at Proterozoic. The orebodies were characterized by obvious strata-bound properties and multistage mineralization. According to the deep analysis on geological characteristics and the genesis, the study has proposed that this deposit is an epigenetic strata-bound polymetallic deposit. It has also concluded the prospecting criteria in this deposit, and believed that there is a greater prospecting perspective in East Kunlun--Qimantage area.
