对许窑沟金矿产出的地质背景、矿床特征、控矿因素及矿床成因等几方面作了系统的论述。提出了断裂、特别是韧性剪切带对成矿的主要控制作用 ;花岗岩与成矿有较大的时差 ,具有穿时、穿层的特点 ,它起着沟通深部与浅部的作用 ,并使深部的含Au流体沿断裂破碎带上升、沉淀而成矿。 This paper systematically discusses the geological background, deposit characteristics, ore-controlling factors and genesis of Xuyaogou gold deposit. The main controlling action of the fracture, especially the ductile shear zone, on the ore-forming is put forward. Granite has large time difference with the mineralization, and has the characteristics of wearing and stratification. It plays the role of communicating the deep part and the shallow part. The deep Au-bearing fluid rises along the fracture zone and deposits and deposits.
