| 摘 要： | 赣南是中国最重要的钨矿产区，矿床类型及其分类方法众多且未统一.通过对赣南地区以往和新发现钨矿资源成果的分析和总结，简要概括了赣南钨矿的类型及其各自的成矿地质特征，并收集了不同类型的赣南钨矿床的流体包裹体岩相学、显微测温、氢氧同位素等相关资料，探讨了赣南钨矿的成矿流体特征.得出赣南钨矿流体包裹体以富液相包裹体为主，少见含子矿物的三相包裹体、CO2包裹体及流熔包裹体，具有不同层次的测温值，显示出多期次流体活动相互叠加的特征.成矿流体为中高温低盐度低密度的NaCl-H2O-CO2体系，成矿流体以岩浆水为主，并有大气降水的混合.

| Abstract: | The Southern Jiangxi Province is the most important producing area of tungsten in China. The types and classifications of the tungsten deposits are numerous and inconsistent. Based on the analysis and summarization of previously and newly discovered tungsten ore resources, the authors brief the types and metallogenic geological characteristics of each type of tungsten deposits in the area. With study on the data involving fluid inclusion petrography, microthermometry, hydrogen and oxygen isotopes of different types of tungsten deposits, the characteristics of metallogenic fluid are discussed. It is concluded that the fluid inclusions are dominated by liquid-rich phase, rarely with daughter mineral-bearing three-phase inclusions, CO2 inclusions and fluid-melt inclusions, with various levels of temperature values, showing the characteristics of multi-stage fluid overlapping. The ore-forming fluid belongs to high temperature, low salinity and low density NaCl-H2O-CO2 system, mainly derived from magma, with later addition of atmospheric precipitation. |
