| 摘 要： | 通过包裹体和同位素地球化学研究,初步得出水银洞金矿具中-低温超高压热液成矿的特点,金赋存于砷黄铁矿环带中,金含量与中等砷含量3％～6％相对应,这可能说明金在砷黄铁矿环带中以亚微米-纳米级的颗粒状不均匀浸染状分布,而不太可能是以晶格金(即以Au~(3 )-As成对置换黄铁矿晶格中的Fe~(2 )-S)的状态存在。矿质主要来源于深部,成矿年龄70Ma。 |

| Abstract: | Initial conclusion in geochemical studies on the inclusion and isotopes of the Shuiyindong gold deposit is that the gold deposit takes on character of epithermal and mosthermal mineralization, there exist gold in the girdle of arsenopyrite, gold contents is corresponding to the mid-grade arsenic content 3-6%, which may indicate the gold disperse as asymmetrical dissemination of sub-micron and nanometer level in grain, not possible present in status of the grid lattice gold, e. g. Au3 - As double replace the Fe2 - S in the grid lattice of pyrite in couples. The mineral materials mainly root in the deep seat, and mineralisation age is 70Ma. |
| Keywords: | Shuiyindong inclusion isotopes |
