摘要
大松坡锡矿是滇西云英岩型锡矿的典型代表。矿体产于燕山晚期花岗岩体内的次级NNW向构造裂隙带中 ,呈脉状成群产出。共圈出含锡云英岩脉 6 0余条 ,但主矿体却只有少数几条。矿体沿走向具有分枝、复合、尖灭再现或尖灭侧现的特点。矿石类型为云英岩型锡矿石 ,矿床成因属气成高温热液云英岩型锡矿床。根据矿体特征及近年开采实践 ,对主矿体连接对比标志进行探讨。
The Dasongpo tin field is the typical representative of greisen tin deposit in west Yunnan,The orebodies are occurred as the vein group in NNW subordinate structural fractures.Although there are 60 tin-bearing greisen veins,only a few of them form the main ore bodies.The orebodies are characterized by branching,composite and discontinuity along the strike.And the tin ore belongs to the greisen type.The genesis of the ore deposits is considered to be the pneumatolitic high T hydrothermal greisen type.
