对水银洞金存款矿床包裹体及同位素地球化学研究的初步结论是：金存款具有浅成低温-中温热液成矿特征，金赋存于毒砂环带中，金含量相当于中品位砷含量3- 6%，表明金在颗粒中呈亚微米-纳米级不对称嵌布分散。不可能存在于网格网格金的状态中，e. G. Au ~（3+）- As对Fe ~（2+）- S在黄铁矿晶格中的双重置换。成矿物质主要来源于深部，成矿年龄为70 Ma。
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.
