| 摘 要： | 矿区位于康滇台隆与盐源一丽江台缘坳陷分界断裂带上。主要控矿构造为S-N向断裂带；矿(化)体形态、产状严格受糜棱岩化控制；主要矿石类型有“石英脉型”和“蚀变岩型”两类硫化物金矿石。成矿物质主要来源于绿片岩，矿化与韧性剪切带密切相关。

| Abstract: | Mianshawa Au Deposit lie in the boundary fracture zo ne between the Kangdian anteclise and the Yanyuan-Lijiang epiplatform depression. Ore-control structures are longitudinal fracture zones and Au orebidies are cont rolled by mylonitized zones. Gold-bearing sulfide ore is divided into quartz vei n type and altered rock type. Ore material was derived from greenschist. The min eralization is related to ductile shear zone. |
