湘东北井冲钴铜矿“三位一体”成矿地质特征及找矿方向探讨

"Trinity"Metallogenic Geological Characteristics and Geological Target for Prospecting of Jingchong Cobalt and Copper Deposit in Northeast Hunan

湘东北地区井冲钴铜矿是湖南省境内首次发现的原生钴矿,本文运用勘查区找矿预测理论从井冲钴铜矿"三位一体"成矿地质特征研究入手,系统分析和总结了该矿床成矿规律,初步认为连云山岩体晚期侵入体为井冲钴铜多金属矿床的成矿地质体,成矿流体主要来源于岩浆热液与大气降水。在系统总结找矿标志基础上探讨了下一步找矿方向。

Jingchong cobalt-copper deposit in northeastern Hunan is the firstly discovered as primary cobalt deposit in Hunan Province.According to the prospecting prediction theory,the metallogenic regularity,and the"trinity"metallogenic geological characteristics of the Jingchong cobalt-copper deposit were systematically analyzed.It is preliminarily believed that the late intrusion of the Lianyunshan pluton is the ore-forming geological body of the Jingchong copper-cobalt polymetallic deposit and ore-forming fluids are derived from mainly magmatic hydrothermal fluids but contaminated by atmospheric precipitation water.Finally,Based on the systematic summary of prospecting criteria,the next prospecting target is discussed.
