摘要
贵州盘县莲花山地区微细粒浸染型金矿主要产于峨眉山玄武岩中,以架底为例,对该区从热液通道、界面、地层与岩性控矿进行分析,认为该区金矿与火山热液通道有关,属于火山热液型金矿,金矿的形成经历了印支、燕山、喜山早期3个阶段成矿作用。金矿体受控于峨眉山玄武岩组与茅口组不整合界面间、峨眉山玄武岩第二段的玄武质火山角砾岩。
The microscopic disseminated gold deposit in Lianhuashan area mainly occurs in pastor of mount Emei, the hydrothermal channel, surface, layer and lithology of Jiadi are studied in this area, it＇ s thought this gold deposit is volcanic hydrothermal type and related to volcanic hydrothermal channel. The gold formation passes 3 periods of Indosinian, Yanshan and Himalayan, the orebody is controlled by unconformity interface of basalt formation and Maokou formation, also be controlled by basalt volcanic conglomerate in the 2nd section of basalt in mount Emei.
