摘要
夹皮沟金矿产于晚太古宙绿岩带的下部层位。北西向的韧性剪切带控制着金矿田和矿床分布,而矿体主要受叠加于韧性剪切带之上的脆性断裂构造制约。金主要来源于围岩。华力西晚期—燕山早期为主要成矿期。属多源、多期的叠生型金矿床。
The Jiapigou gold deposit lies in the lower part of the late Archaean greenstone belt. Distribution of the goldfield and the gold deposits is controlled by the NW-trending ductile shear zone, but the orebodies are controlled mainly by the brittle fractures overlying the ductile shear zone. The gold is derived from the country rocks.The principal metallogenic epoch is the late Variscianearly Yanshan. It belongs to polysources and multiple-staged superimposed type gold deposit.
