摘　　要：阳山金矿床属于卡林型—类卡林型金矿床,是研究陕甘川“金山角”金矿资源产出背景环境以及成矿过程的典型矿床。本文研究表明:阳山金矿床明显受控于断裂破碎带,尤其是层间破碎带,对金矿床控制明显;金矿床的矿石类型较复杂,具有奠定的热液充填型矿石特征,说明金矿床的形成与燕山期含矿热液的演化关系密切;中泥盆统三河口组可能为主要的矿源层,区域层位稳定,具有较大的找矿潜力。Yangshan gold deposit belongs to Carlin type and Carlin like type gold deposit.It is a typical deposit to study the background environment and metallogenic process of jinshanjiao gold deposit in Shaanxi,Gansu and Sichuan.The study shows that:the Yangshan gold deposit is obviously controlled by fault fracture zone,especially interlayer fracture zone;the ore type of the gold deposit is complex and has the characteristics of established hydrothermal filling type ore,indicating that the formation of the gold deposit is closely related to the evolution of ore bearing hydrothermal solution in Yanshanian period;the Middle Devonian Sanhekou formation may be the main source bed with stable regional horizon It has great prospecting potential.
