大宝山铜多金属矿矿床成因及成矿模式研究

A Study on the Genesis and Metallogenic Model of the Copper Polymetallic Deposit in Dabaoshan

大宝山铜多金属矿是粤北重要的多金属矿床.为摸清该矿床成因及成矿模式,实现外围深部找矿突破,文章归纳整理了该矿床的区域地质背景和矿床地质特征,并结合岩浆岩年龄分析,初步论证了该矿床属于岩浆热液型矿床,其成矿历史分为3个阶段,即早泥盆世形成硫化物阶段;燕山期形成铜铅锌钼钨矿阶段;后期褐铁矿形成阶段.

The copper polymetallic deposit in Dabaoshan, Guangdong province is an important polymetallic deposit in the northern of Guangdong. In order to find out the genesis and metallogenic model of the deposit and realize the breakthrough of deep prospecting in the periphery, this paper summarizes the regional geological background and geological characteris- tics of the deposit, and, on the basis of magnlatic age analysis, it preliminarily proves that the deposit belongs to magnlatic hydrothermal deposit. In Yanshan period, copper lead zinc molybdenum tungsten was formed, and later the limonite formation stage formed.
