摘要
黔西南地区卡林型金矿及与其相关的次生富集型金矿,是以海西期峨眉山玄武岩的边缘相火山碎屑岩为矿源层的再造矿床。与其相关的次生富集型金矿,是卡林型金矿或其矿源层的风化淋滤产物。碳酸盐岩与粘土岩的交界面及细粒碎屑岩中的糜棱岩等的半透膜渗析效应。
In the southwest of Guizhou, the Carlintype and the associated secondary enrichmenttype gold deposits are regenerated deposits whose source beds are marginal facies pyroclastic rock of the Haixinian Ermeishan basalt. The secondary enriched gold deposit related to the Carlintype gold deposit are believed to be the product of weathing and leaching of the Carlintype deposit or its source bed. The interface between carbonate rock and clayrock, as well as mylonite in fine grained clastic rocks act as semipermeable membranes which played important roles in the mineralizing process of gold deposit.
