黑龙江省伊春市丰林林场车间南沟铅锌矿成矿远景分析

Metallogenic prospective analysis of the Nan Gou lead zinc deposit in Fenglin forest farm, Yichun City, Heilongjiang Province

下寒武统铅山组为矽卡岩型铅锌、铁多金属矿产的主要矿源层,被后期二长花岗岩侵入与变质岩系发生广泛接触交代作用,促使变质岩中的成矿物质活化。主要的容矿构造为断裂、矿体与地层接触面和不同期次界面。矿体与地层的接触界面是重要的控矿构造,主要为铅锌矿,有伴生金银、铜矿产出。

The Lower Cambrian Yanshan Formation is the main source bed of skarn Pb-Zn-Fe polymetallic minerals,which was extensively contacted and metasomatized by late monzonitic granite intrusion and metamorphic rock series, and promoted the activation of metallogenic materials in metamorphic rocks. The main ore hosting structures are faults, contact surfaces between ore bodies and strata and different stages of the interface. The interface between ore body and stratum is an important ore-controlling structure, mainly lead-zinc deposits, accompanied by gold, silver and copper deposits.
