【摘要】 化马湾金矿产于新太古代绿岩带变质地层中,赋存于中浅层韧性剪切带内,矿化体呈脉状,平面上具有膨缩和尖灭再现特点。绿岩带地层为金矿化之矿源层,岩浆作用为金矿化带的形成提供了热源,构造作用对含金热液的流动与迁移提供了通道。该金矿矿床成因为绿岩带变质热液—构造蚀变岩型,按工业类型属低硫含银自然金矿石。更多还原

【Abstract】 Huamawan gold deposit is produced in Neo-proterozoic greenschist metamorphic strata, and occurs in middle-low ductile shear belt. Mineralization body occurs as vein type, and has the characteristics of dilatation, minimization, vanish and reappearance in surface. Strata in greenschist belt are source of gold mineralization belt, and tectonic function provides road for gold-bearing thermal flow and transformation. The origin of this gold deposit is metamorphic thermal-tectonic alteration type. According to industrial type, it belongs to low-sulphur and siliver-bearing gold deposit.更多还原
