摘　　要：该矿床中以平行陡倾的含矿石英脉为特征的矿体 ,在构造变形过程中常产生石香肠化。由于局部应力环境的差异 ,所形成的石香肠构造样式也各不相同 ,并控制了矿体形态及有用矿物组分的分布。以不同样式石香肠构造在矿区的分布特点进行了构造分区 ,并对其形成机理作初步探讨。The paralleled-orientated and heavyly dipped silver-gold-bearing quartz veins from the Yindonggou silver-gold orefield are usually deformed and the boudinage structures formed. As a resulf of different stress environment,there exist obvious different styles of boudinage struetures which controlled the form of orebodies and distribution of ore mineral components. According to distribution of boudinage struetures, the orefield is divided into several structural regions and their forming mechanism is discussed.
