摘　　要：蓬家夼金矿赋存于中生界莱阳组和下元古界荆山群之间的剥离断层中，矿体产出严格受层间滑脱断层带控制，矿体的厚大部位产在层间滑脱断层产状由陡（４５°～５０°）变缓（１５°～２０°）处。通过对蓬家夼金矿田家矿区东西两翼成矿地质条件的研究，认为山西段和东井口段同样是成矿有利地段，应进行详细勘探。Pengiakuang gold deposit was located in the denudational faults between the conglomerate of Mesozoic Laiyang Formation and the metamorphic complex of Proterozoie Jingshan Group.The orebodies were controlled by the denudational faults.The orebodies become thicker when the faults become steeper(from 15°～20°to 45°～50°).Based on the study of the metallogenic geological enviroment in Shanxi and Dongjingkou region,we proposed some exploratory direction in these areas.
