摘要
金堡铅锌矿区位于扬子准地台与华南褶皱带的接触带上,属典型的断裂控矿。根据控矿断裂与矿体的关系,可把该区断裂分为成矿前、成矿期、成矿后三期,并初步确定成矿期为加里东期和燕山期;按照矿床矿石矿物的组合、结构构造,相互关系及形态特点,又将成矿期识别为黄铁矿—石英阶段、石英—多金属矿化阶段、碳酸盐—多金属矿化3个成矿阶段。本文试图从区域和矿区构造分析研究入手,进行找矿前景分析。
Jinbao lead - zinc field is located in the contact strip of Yangzihuai platform and Huanan folded zone, its control of mineralization is controlled by fracture typically. According to the relationship of ore control fracture and ore body, it can divide the fracture into three stages： before mineralization, mineralization period, after mineralization, initially fix the metallogenic epoch are Caledonian and Yenshan stage. According to the mineral combination of ore in deposit, the structure conformation, mutual relationship and shape characteristic, it divided the mineralization period into metallogenic stages ： iron pyrites - quartz stage, quartz - poly- metallic mineralization stage, carbonate - polymetallic mineralization stage. In this paper, it try to analysis the prospection from study the structure of field and region.
