摘　　要：金窝子金矿床产于华力西期黑云母二长花岗岩及其围岩上泥盆统金窝子组中,矿化类型为石英脉型和蚀变岩型。研究表明华力西期—印支期花岗岩系统和低角度韧脆性断裂及其次级高角度张性-张扭性断裂系统与成矿有密切的时空及物质联系,是金矿化的主控因素;矿化类型受构造应力场和断裂力学性质控制。The Jinwozi gold deposit occurred in Hercynian biotite adamellite and Jingwozi Formation(Upper Devonian). Its mineralization type is the quartz-vein one and the altered-rock one. This study reveals that a granitic magma system, and low-angle ductile-brittle fault and high-angle extension-tensionshear second order fault system closely associated with the minerlization in terms of space, time and materials, accounts for the gold minerlizaion. The minerlization types are controlled both by the tectonic stress field and the fracture mechanic property.
