摘要
在研究矿床地质特征的基础上,认为内蒙古吉林宝力格银矿床是火山喷流沉积-燕山早期岩浆热液叠加改造块状硫化物多金属矿床。区域上EW向古生代形成的裂谷型上泥盆统-下二迭的浅变质沉积-火山岩系,是本区找矿的最佳区段。含银流纹质晶屑凝灰岩是银多金属矿的重要找矿标志。
Based on studies on geological character of the deposit, it is an early stage volcanic projection - deposition of Yanshanian magmatism and the massive sulfide polymetllic deposit which is reformed by hydrothermal fluid. Regional E - W direction rift type epizonal metamorphic - volcanic formation of upper Devonian and low Permian series is available sector for prospecting in the area. Bearing - silver rhyolitic crystal tuff is the important criteria for ore prospecting in the silver polymetUic deposit.
