摘要
夹皮沟金矿区韧性剪切带的空间分布大体上有三组,即NE、NW和SN。而NE向形成早于NW和SN方向。对金矿化具有控制作用,特别是NW向不但发育,且规模大,有利提供矿化空间和储矿构造。对矿化带、金矿床(点)和矿化类型等均起到控制作用。最后提出要高度重视在韧性剪切带和糜棱岩带中找金。
The spatial distribution of ductility shear zone of Jiapigou gold deposit can be roughly divided into three groups :ortheastern,northwestern and south-north direction:but the northeastern shear zone formed earlier than the northwestern and south-north ones. They controlled the distribution of gold mineralization.in which the northwestern shear zone is not only especially well develloped and broad in scale,but also provides space and ore bearing structure for mineralization. They also control the distribution of mineralization zone and gold deposit (prospect) and the type of mineralization.It is suggested that great attention should be paid to prospecting the gold ores in ductility shear zone and mylonite zone.
