摘　　要：大松坡云英岩脉型原生锡矿体赋存于古永岩群小龙河岩序猫舔石单元花岗岩岩体之边缘部位的北北西向组构造裂隙中,主要呈群呈带脉状产出。本文以3个钻孔采集的516件地球化学样品,进行了钨、锡等16个元素测试分析和整理、统计制图等,结合主矿体特征,对主矿体深部走向、倾向推断预测。Ore bodies of the Dasongpo greisen vein type Sndeposit are mostly in groups and belts,and are hosted in the NNW trending tectonic fissures at the edge of the granite body of the Maotianshi Unit,Xiaolonghe Lithostratigraphic Sequence,Guyong Group.A total of 516 geochemical samples collected from three drilling cores were subjected to analytical testing,data compilation,and statistical mapping for 16 elements including W and Sn,and the deep-seated strike and dip direction of themain ore body werepredicted.
