摘要
赣西卡林型金矿床产于扬子板块东南缘萍乡—高安坳陷带内,赋矿围岩为二叠系下统茅口组和三叠系下统大冶组细碎屑岩和不纯碳酸盐岩,金矿体产于断裂破碎带、层间破碎带、不整合面、密集裂隙带等构造部位,呈层状、似层状、透镜状产出。金成矿受地层岩性、构造等因素的控制,重点找矿远景区是坳陷带内两大推(滑)覆构造对冲带南侧的金矿化异常区。
Carlin type Au deposits in the west Jiangxi province occurring in Pingxiang-Gaoan depression zone at the SE margin of Yangtze plate are hosted by the fine-grained clastic rocks and impure carbonate rocks of Lower Permian Maokou Formation and Lower Triassic Daye formation. The ore bodies are in layer or layeroid and lenticular forms located in cataclastic fracture zones, interformation cataclastic zones and unconformable plane. Generally such Au deposits are controlled by lithologies and structures. The mineralized anomaly areas in south of the two big nap zones are key prospects for furthor Au ore exploration.
