摘要
针对海沟金矿是大型石英脉型金矿床 ,矿体严格受走向NE -NNE的断裂构造控制 ,控矿构造应力作用方式有三种这一状况 ,阐述了其成矿期最大主压应力方向为NE向。说明控矿断裂构造在成矿阶段的应力处于张扭性状态 ,此应力状态有利于矿液充填、沉淀。并指出该区NE
Haigou gold deposit is a quartz vein type one.The orebody is strictly controlled by NNE-NE faulted structures.There are three types of ore-controlling structures in tectonic stress field.The stresses state is NE trending compression in metallogenic epoch and the ore-controlling faulted structure is in a tenso-shear state during metallogenic epoch, which is favorable for the infilling and precipitation of ore solution.NE-NNE faults are pointed out to be targets for further prospecting in this district.
