岩、矿石的显微组构研究对水银洞金矿成因的指示作用

Instruction function of research on rock micro fabric to the origin of Shuiyindong gold deposit

黔西南水银洞金矿是一特大型富金矿床,矿体成群多层、顺层产于龙潭组地层中,通过系统研究水银洞金矿赋矿地层岩石及矿石的显微组构特征,以及与金矿成因联系密切的硅化及黄铁矿化特征,均显示为同沉积—成岩特征,共同指示水银洞金矿沉积—成岩后期轻微改造的成因机制。

Shuiyindong gold deposit in Guizhou province is a super-huge rich gold deposit, and the ore bodies preserve in the Longtan stratum in groups along the level. Studies on rock and ore micro fabric that control mineral preservation stratum of the deposit, and the siliconization and pyritization contacted with gold mine origin reflects the characteristic of syndeposition-diagenesis, which indicates the sediment-diagenesis and later stage mild reconstrtictive genetic mechanism of Shuiyindong gold deposit.
