石棚沟金矿床严格受北东向韧性剪切带控制，赋矿构造主要为后期叠加于韧性剪切带之上的北东、北西向脆性剪切裂隙，以北东向为主。矿体围岩为花岗质糜棱岩，并与煌斑岩关系密切。矿石类型为贫硫化物石英脉型，呈细脉状、网格状分布，单矿脉规模一般长不超过50 m，宽不超过1 m，走向及倾向上膨缩明显并很快尖灭。结合区域韧性剪切带型金矿床构造演化与金矿化类型叠加复台关系模式认为，石棚沟金矿床处于韧性带顶端，向深部找矿潜力较大。

Shipenggou gold deposit is strictly controlled by NE trending tenacity shear zone, The ore occurrence structures are NE, NW brittle shear fracture, which late superimposed on tenacity shear zone, the NE is mainly. The wall rocks is granitic mylonite, has close relation with lamprophyre. The ore type is poor sulifde quartz vein type, thread vein, grid distribution, single vein scale generally no longer than 50m, the width is not more than 1m, and the trend and tendency expand obviously and pinched out quickly. Combining with relation model of gold deposit tectonic evolution of regional tenacity shear zone type and gold mineralization type superposition compound, the authors consider that Shipenggou gold deposit lied at the top of tenacity shear zone, and has the deep prospecting potential.
