| 摘 要： | 通过对某银金矿微量元素、稀土元素、同位素地球化学等方面的系统研究，对含矿岩系和矿体物质组分迁移富集规律的初步探讨，认为该矿床为沉积一热液改造型，成矿元素组合为Au－Ag-Pb-Cu-As-Hg，矿体物质来源与围岩有密切关系，成矿中-低温热液来自地表浅层水，成矿时代为236Ma。

| Abstract: | By means of Systematic study on microelemental geochemistry, REE geochemistry, isotope geochemistry and migrating-enrichment law of the material components in the ore -bearing rock series and ore bodies, it is concluded that a certain silver-gold deposit in Yunxi,Hubei, is a sedimentary-hydrothermal reformation deposit, the metallogenic elemental association is An - Ag - Ph - Cu -As -Hg, the ore source is intimately related to the country rocks, the surface shallow water is the source of the metallogenic meso - epithermal solution and the metallogenic epoch is 236 Ma. |
