| 摘 要： | 流体包裹体研究表明:湘西江南型金矿床为中～低温热液矿床,成矿流体为地下热水与变质水混合而成的中等盐度、密度的弱还原性热液,成矿作用是在弱碱性条件下进行的。流体包裹体研究同时还表明:断裂构造对湘西江南型金矿床的矿化具有明显的控制作用。

| Abstract: | Fluid inclusion studies indicate that the Jiangnan-type gold deposits in western Hunan Province are epi-to mesothermal deposits. The ore-forming solution is a weakly reducing fluid with a moderate salinity and density, which resulted from the mixing of metamorphic water and geothermal water. Au mineralization proceeded under a weakly alkalic condition. Simultaneously, the study also shows that mineralization of the Jiangnan-type gold deposits is controlled obviously by fault structures. |
