摘要
湖南黄土店金矿区,原被认为是粉砂岩或粘土岩分布的地方。但经笔者野外考察及室内镜下鉴定,岩石化学成份测试,岩石矿物成份的计算和图解后认为:该金矿区有云煌岩岩脉产出,并发生了浅变质作用,岩石可定名为变余云煌岩。
The Huang Tu Dian gold deposit in Hunan used to be thought as the distributive place for microclastic rock and clay rock. According to the inspection in the field and identification under micr- oscope in the laboratory testing of chemical composition of the rosks; and through the calculation and diagramming of the mineral composit- ion in rock,the writer believes that there are the mineral vein of blasfo-mineffe developed in this gold deposit and it had undergone a kind of metamorphism,therefore,the rock can be named as blastom- inette.
