摘　　要：滇东南地区金、锑矿中方解石是最主要的脉石矿物之一,其形成期分为成矿前期、主成矿期、成矿晚期、成矿期后四种类型。各类型方解石无论野外产状、物性标型特征及微量元素地球化学特征均不一致。通过方解石地球化学和物性标型特征研究,可利用方解石地球化学和物性标型特征辅助寻找金、锑矿。Calcite ie one of the most principal gangue mineral of Au,Sb deposit in SE Yunnan,which can be divided into 4 forming stages of early stage of metallonesis,principal metallogenesis stage,late stage of metallogenesis and post-metallogenesis stage.Various calcites are different in field occurrence,typomorphic characteristic and trace element geochemical characteristic.The study on calcite geochemical and typomorphic characteristic is helpful in the prospecting Au,Sb deposit.
