胶东山后—上庄地区断裂控矿分析

Analysis on Fault Ore-controlling in Shanhou-Shangzhuang Area , Jiaodong

山后—上庄地区位于胶东招平断裂带中南段。区内金矿化受招平断裂带和涧里断裂及两侧的次级断裂控制。通过对断裂的分析,结合野外第一手资料,认为NNE、NE向断裂是区内主要的导矿和容矿构造,控制着矿体的分布;金矿常分布在环形构造边缘或产在环形构造与线形构造的交会处。下一步找矿工作中,深部探矿应在16～24线之间,但同时应注意是否存在第2个无矿间隔;外围探矿应以西萌山水库—黄岭一带为今后工作的重点。

Shanhou-Shangzhuang area is located in the middle south segment of Zhaoyuan-Pingdu fracture belt.Gold mineralization is controlled by Zhaoyuan-Pingdu,Jianli fault and secondary fractures on its two sides.Though analysis of faults,combination of field information,we think NNE、NE trending faults are the main leading and contain the ore structure,it controls the distribution of orebody.Gold mine distribute at the edge of circular structure and intersection of circular and linear structure.We point out the next prospecting,deep exploration should be between 16 to 24 lines.Also,we should attention if there is the second barren interval,external prospecting should be in the region from Ximeng Reservoir to Huangling as the focus in the future.
