摘　　要：从矿体空间展布特征、产状、顶底板及边缘形态可以看出,个旧层间锡石-硫化物矿床明显的受到构造的控制;从断裂构造的含矿性可以看出,断裂(裂隙)中的成矿元素含量远高于围岩,是层间氧化矿的有利赋存部位。此类型矿床具有热液充填(交代)成因,属于燕山晚期花岗岩岩浆期后热液矿床。From the distribution features and occurrence of orebodies and their shapes,it can be seen that the cassiterite-sulfide deposits in the Gaosong ore field of Gejiu are obviously controlled by structures; ore-bearing potential of the structures shows that the contentsof ore-forming elements in the faults are far higher than in the wallrocks.The type of deposits is of hydrothermal filling (metasomatic) origin.
