我国卡林型金矿研究现状

Present Situation of Research into Carlin-type Gold Deposits in China

卡林型金矿是我国重要的金矿类型之一,通过对比研究前人有关卡林型金矿的资料发现,我国卡林型金矿产出于具有拉张-沉积-碰撞造山地史演化的地区,为中低温热液矿床,主要赋矿岩石为不纯的碳酸盐岩,其余为浅变质岩、火山碎屑岩等。流体包裹体及同位素组成揭示了我国卡林型金矿成矿热液来源的多样性和复杂性,其不仅仅是前人认为的来自于赋矿地层中。

Carlin-type gold deposit is one of important gold deposit types in China. The study indicates that Carlin-type gold deposits in China occur as mesothermal and epithermal ones in a tensional-sedimentation- collision orogenic setting, and are confined to an impure carbonate rock or epimetamorphic rock or pyroclastic rock. Data on fluid inclusion and isotopic composition reveal that ore fluids for the Carlin-type gold deposits in China were of diversity and complexity.
