摘要
农坪金(铜)矿床受控于东西向断裂构造带,产于英云闪长(斑)岩蚀变岩中,与闪长玢岩密切相关。矿床成因类型为次火山热液含金蚀变岩型。矿床类型特殊,外围找矿潜力较大,对珲春地区金、铜找矿具有指导意义。
Nongping Au (Cu) deposit is controlled by W -E feaulted strctural zone and occurs in tonalite, tonalitic porphyry altered rocks which is closely related to tonalitic porphyrite. The origin type of ore deposit is a subvolcanic hydrothermal gold - bearing, altered rock type. Because of unusual deposit type, it has a considerable potentiality for prospecting at its adjacent area, and has a guidable significance to the Au, Cu deposit in the Hunchun area, Jilin province.
