折腰山矿床地质特征及深部找矿前景

The Geological Characteristics and Deep Prospecting Prospect of Zheyaoshan Deposit

折腰山矿床产于折腰山古火山喷口构造内,受火山通道制约并受北西向和北东向两组继承性成岩断裂系统控制,产于石英角斑岩类的粗碎屑火山岩中,矿体成群产出、成段集中,绿泥石与成矿关系密切。近年来,深部找矿成果显示,已知矿床深部仍有较大的找矿潜力,再找矿前景乐观。

Zheyaoshan deposit developed in the tectonic of ancient volcanic vents, it is restricted by volcanic conduit and controlled by two sets of inheritance of NW and NE fault system. It occurs in coarse elastic volcanics of quartz keratophyre class, with its ore-body developed in groups and concentrated in senents, and chlorite closely related to the mineralization. Recent years＇ deep prospecting results indicate a greater prospecting potential in the deep depths of known deposits and a bright future for one re-prospecting.
