赤峰—朝阳地区金矿控矿因素及找矿方向探讨

RESEARCH ON CONTROL FACTOR AND PROSPECTING DIRECTION OF GOLD DEPOSIT IN CHIFENG-CHAOYANG AREA

赤峰—朝阳地区金矿可分为金厂沟梁式、安家营子式和柴胡栏子式,金矿体均受断裂构造的直接控制。区域太古宙变质岩的潜在含金性、多期次多成因花岗岩类的活动、长期活动的断裂系统是金矿集中区的主要控制因素。

The Chifeng-Chaoyang area is an Au-deposit-concentrated area in Liaoning province. Several styles of Au deposit occur in the area, such as Jinchanggouliang style, Anjiaying style and Caihulanzi style. Au ore bodies are directly controlled by faults. The Au-bearing capacity of the regional Archean metamorphic rocks, the multi-staged and multi-genetic granilic activities and long-lived fault system are factors controlling the Au-deposit-concentrated area.
