| 摘 要： | 金谷山金矿床产于上古生界二叠系柯岛组地层中，矿化类型为构造蚀变岩型。火山喷发-沉积作用形成的中酸性火山-碎屑岩系，是金矿形成的基本因素和矿源层，变质变形作用是金矿形成的根本因素，脉岩活动是金矿成矿的叠加因素。矿体受韧性剪切变形变质带控制，矿床成因为变质热液与岩浆热液叠加的复合型。

| Abstract: | The Jingushan Au deposit occurred in the Kedao Formation strata, the mineralizing type belongs to structural altered rock one. The intermediate acidity volcano --clastic rock series formed by volcanic eruption and sedimentation is a basic factor and source bed for gold- forming, metamorphic deformation is a basic factor for gold-forming, vein rock action is a superimposed factor for gold--forming. The ore bodies were controlled by ductile shear metamorphic deformation belt, the genesis of the deposit is a superimposed compound one by metamorphic hydrothermal process and magmatic hydrothermal process. |
