胶东上庄金矿构造控矿特征及找矿方向

The feature of structural control and exploration direction of the Shangzhuang gold deposit in Jiaodong

上庄金矿区金矿化主要分布于主干断裂———招平和涧里—跃进村断裂及其两侧的次级断裂中,严格受断裂或韧性剪切带的控制,金矿化在断裂产状发生变化、构造叠加改造部位,节理密集带与破碎带的复合部位富集。找矿方向为①号脉以南至涧里—跃进村断裂与主断裂交汇处;涧里—跃进村断裂带两侧密集次级断裂及深部;招平断裂入字型构造部位,即①、②、⑧、⑨、⑩号脉深部。

The mineralization of the Shangzhuang gold deposit mainly occures in the master fault(the Zhaoping fault), the Jianli to Yuejincun fault and the subfaults of both sides, and strictly controlled by faults or ductile shearing belt. The gold mineralization enriched in the places where the faults occurences changed, the structure overprinted and reformed, and the closedjointed area combined with the fraction area.This paper point out the exploration direction of the mineral area: the south of 1st gold mineral vein of the intersection part of the Jianli to Yuejincun fault and master fault; the dense subfaults and depth of the both sides of the Jianli to Yuejincun fault belt; the depth of 1st, 2ed, 8th, 9th and 10th gold mineral veins.
