摘　　要：招平断裂带是胶东地区的重要控矿构造,大磨曲家金矿是赋存于该断裂带北段的大型破碎带蚀变岩型金矿床。区内302号破碎蚀变带与上下盘次级断裂共同组成大磨曲家金矿控矿断裂系统,并控制了金矿体的产出。矿区存在构造—蚀变—矿化的水平分带性。总结了矿床矿化富集规律,进行了深部找矿预测。The Zhao -Ping fault belt is a important ore -controlling structure . Damoqujia gold deposit is located in the north of the structure belt . It is a large - size gold deposit of faulted belt altered rock type. The No. 302 faulted belt and the secondary faults compose Damoqujia gold deposit ore- controlling faulted system and control the gold body＇s pattern. The gold deposit presents the horizontal zoning characteristics of structure→altemation → gold mineralization. This paper summarizes the deposit mineralization enrichment features and puts forward the deep ore bodies prediction.
