摘要
争光金矿床产于中奥陶统多宝山组中性火山岩和燕山期中酸性侵入体中,赋存于NWW、NNW向断裂构造带内,矿体呈脉状,具有膨缩和尖灭再现特点。中奥陶统多宝山组中性火山岩地层为金矿之矿源层,燕山期中酸性侵入体岩浆作用为金矿的形成提供了热源,构造作用对含金热液的流动与迁移提供了通道。该金矿矿床成因为热液—构造蚀变岩型。
Zhengguang gold deposit is produced in Duobaoshan volcanism and Yanshan invasion, and occurs in NWW NNW tectonic belt. mineralization body occurs as vein type, and has the characteristics of dilatation, minimization, vanish and reappearance. Duobaoshan volcanism are source of gold mineralization belt; Yanshan invasion are hot source of gold mineralization, tectonic function provides road for gold-bearing thermal flow and transformation. The origin of this gold deposit is tectonic alteration type.
