湖南衡阳盆地国庆矿区物化探找矿方法应用效果

国庆矿区毗邻黑石沱、盐田桥铜矿床,属同一控含矿构造,东部为燕山早期第二阶段(γ52-b)侵入的白石峰岩体,构造膨胀变异,岩浆热液活动等造就了良好的成矿地质环境,因控含矿构造在本区隐伏于红盆之下,本文通过阐述对地电化学集成技术剖面测量和可控源大地电磁测深(CSAMT)测量工作方法的综合应用,推断预测隐伏构造的展布,与钻孔验证情况对比,总结本区地质特征及物化探找矿方法的效果。为本区乃至整个衡阳盆地隐伏控含矿构造的找矿工作提供了有效可靠的方法和手段。

Application of geophysical and geochemical prospecting methods in Guoqing mining area,Hengyang basin,Hunan Province

Guoqing mining area is adjacent to heishituo and yantianqiao copper deposits,which belong to the same ore-bearing structure.In the East is the baishifeng rock mass intruded in the second stage of early Yanshan (γ52-b).The tectonic expansion and variation,magmatic hydrothermal activity and so on have created a good metallogenic geological environment.Because the ore-bearing structure is concealed under the red basin,this paper describes the profile measurement of GEOELECTROCHEMICAL integration technology And the comprehensive application of CSAMT survey method,infer and predict the distribution of concealed structure,compare with the drilling verification,summarize the geological characteristics and the effect of geophysical and geochemical prospecting methods in this area.It provides an effective and reliable method and means for the prospecting of concealed ore-bearing structures in this area and even the whole Hengyang basin.
