摘要： 研究了金厂峪金矿床地质特征和地球化学特征,其流体包裹体研究显示成矿温度为中高温热液环境,成矿流体为低盐度,同位素显示物质来源具有深源的特征.稀土-微量元素特征显示金成矿作用具有排斥稀土元素的作用,Bi可作为富矿指示剂.矿床体的石英大脉和复脉赋存特征及成因机制显示金厂峪金矿床主要赋存于韧性剪切活动后期的脆性构造-挤压片理化带内,成矿空间为受韧性剪切带控制的后韧性剪切带型金矿床.

Abstract: The geology and geochemical characteristics of Jinchangyu gold deposit were studied, and the results of its fluid inclusions showed that the ore-forming fluid is a low salinities, medium to high temperature fluid, and the isotopic features display its deep-source characteristics. The study on trace element and REE demonstrated that gold mineralization excludes rare earth elements and, Bi can act as indicator for high grade ore. The genetic mechanism and occurrence characteristics of wide quartz veins and composite veins indicated that the ore bodies mainly occur in brittle structure-extruded schistosity zone, and the ore spatial distribution is controlled by ductile shear zone.
