| 摘 要： | 小草坝钨矿床是一个新探明的大型钨矿床。本文通过矿石的光、薄片鉴定和电子探针分析,对矿石矿物特征进行了初步研究。结果表明,矿石主要有用金属为钨、钼,以白钨矿、辉钼矿形式存在;根据矿物组合特征、矿物间穿插关系及矿床地质特征,初步划分了成矿阶段,认为小草坝钨矿床的形成主要经历了矽卡岩阶段(包括早期矽卡岩阶段和晚期矽卡岩阶段)、热液阶段(包括石英-氧化物阶段和石英-硫化物岩阶段)。

| Abstract: | The Xiaocaoba is a newly discovered large-size W deposit. Ore minerals are identified by polished and thin sections and analyzed by electronic probe as W-bearing sheelite and Mo-bearing molybdenite. Based on geological characteristics of the deposit, the ore mineral characteristics and their cutting relationship the metallogenic process is preliminarily divided into skarn stage and hydrothermal stage. |
