| 摘 要： | 本文从地层含矿性、同岩浆活动的关系及同位素组成特征等几个方面进行分析 ,以阐明湘中锡矿山式锑矿成矿物质来源于构造岩浆活化作用形成的区域性深部上升流体。虽然赋矿层位相对集中 ,但不存在明显的锑矿源层。铅同位素研究表明矿石铅来源于深部均化条件下的铅同位素演化系统 ,与围岩地层铅同位素明显不同。硫同位素显示矿石硫为均一化程度较高的混合深源硫。包裹体水氢、氧同位素组成介于大气降水与初生水之间 ,为混合水类型

| Abstract: | The Xiangzhong (central Hunan) area is a world\|known antimony metallogenic province , hosting a great number of antimony deposits, of which the Xikuangshan\|type is most important. Study on the source of ore\|forming materials for the Xiangzhong antimony deposits has arouse a hot discussion. Based on Sb contents of the strata and the relation with magmatic activities, as well as the isotopic characteristics, this paper shows that the ore materials were derived mainly from the rising plutonic fluid associated with Late Yenshanian\| Early Himalayan tectonic\|magmatic activities. |
