| 摘 要： | 个旧锡多金属矿区处于多个深大断裂和丁字型裂谷交汇部位，燕山期花岗岩穿切三个大的含锡铜多金属高背景地层。成矿期矿化体上部帽状泥质地层为遮挡层。矿床具有明显的矿物、元素分带。根据已知成矿模式，可成功预测数百米乃至千米埋深的矿体空间分布和储藏远景

| Abstract: | The Gejiu super large Sn polymetallic deposit in Yunnan is located in the convergent area of three or more deep fractures and "T" shape rift . Three main (Sn,Cu) bearing strata were intruded by the Yanshannia granite intrusives. A cap shaped argillaceous cover existing on the upper part of ore bodies works as a shielding layer. This ore deposit is characterized by mineral and element zonation. By the known metallogenic model, the spatial distribution of ore bodies and the potential reserves can be possibly predicted. |
