招平断裂带北段北延构造及找矿方向浅析

招远-平度断裂带是胶西北地区三大控矿断裂之一,其北部延伸趋向于破头青断裂带.本文分别从招平断裂带北部的2条主要控矿断裂带向深部延伸的规模,蚀变破碎程度、矿化显示、所控制的矿体数量、主矿体规模、所探获资源量、典型矿床特征等方面进行对比,分析确定九曲蒋家断裂带为招平断裂带北延的主要控矿断裂,预测其深部具有较大的找矿潜力.

Discussion on the Northward Extension Structures and Its Prospecting Directionof in the Northern Section of Zhaoping Fracture Zone

ZhaoyuanPingdu fracture zone is one of three major orecontrolling fracture zones in Jiaodong area. Its northwest extension tends to be Potouqing fracture zone. From the aspects of the scale of deep extension of two fracture zones in the north of Zhaoping fault belt, the degree of alteration and fragmentation, and the mineralization display, the number of ore bodies controlled, the scale of main ore bodies, the amount of resources explored, and characteristics of typical deposits, it is determined that Jiuqujiangjia fracture zone is the main orecontrolling fault in the northern extension of Zhaoping fracture zone. It is predicted that there is a great prospecting potential in its deep part.
