| 中文摘要: |
| 滇东南大庄锑矿床地处华南褶皱系滇东南褶皱带个旧褶皱束，锑矿体主要产于上二叠统龙潭组上段及下三叠统永宁镇组下段破碎带及次生破碎带硅化含泥白云岩、白云质灰岩中，矿体明显受断层的控制。文章对大庄锑矿床地质背景、矿床地质特征以及土壤化探异常等方面进行了系统论述，并认为锑矿矿石类型主要为方解石-辉锑矿型，围岩蚀变主要表现为碳酸盐化、硅化、黄铁矿化及绿帘石化等；硫同位素特征表明成矿物质可能来源于深部物源区，成矿热液主要来源于岩浆水与大气降水的混合；矿床成因类型为受断裂控制的热液改造型矿床。 |
| 英文摘要: |
| The Dazhuang antimony deposits in southeastern Yunnan is located in the Gejiu fold bundle, southeastern Yunnan fold belt of the south China fold system. Antimony ore body occurs mainly in silicified muddy dolomite and dolomitic limestone within fractural zone of Upper-Longtan formation of the Upper Permian and the lower-Yongningzhen formation of the lower Triassic Series and is strictly controlled by the fault. Geological background and characteristics and soil geochemical anomlies are described systematically. Calcite-stibnite ore is main ore type. Wall-rock alteration includes carbonatization, silicification, pyritization, epidotization and so on. S isotopic features indicate that ore materials may come from the deep source area, the ore fluid is the mixture of magmatic water and meteoric water. Genetically it is reworked fault-controlled hydrothermal deposit. |
