摘　　要：滇东南是云南省重要的锑矿产地。区域断裂控制着该区矿床(点)的分布,层间破碎带、岩层褶皱虚脱部位是锑矿体重要的赋存空间,具有工业意义的锑矿体主要形成于下泥盆统坡脚组(D_(1)p)和翠峰山组(D_(1)c)中。硅化是最重要的锑矿找矿标志。广南-西畴南部、丘北北部为锑矿找矿的最佳找矿地带。The important Sb ore occurrence site of Yunnan is in SE Yunnan.The deposit distribution is controlled by the regional fault,the interlayer fracture zone and the fold prostration place is the important occurrence space of Sb deposit.The commercial Sb orebody is mainly in Lower D Pojiao Formation(D_(1)p)and Cuifengshan Formation(D_(1)c).The silicification is important prospecting criteria.The S part of Guangnan-Xichou and the N part of Qiubei are the best prospecting area.
