摘要: 近几年,金属矿产的地质勘查重点逐步向寻找深部隐伏矿床目标转移,地质找矿的难度和投资风险加大。综合物探方法作为深部矿产勘查的重要手段,具有经济、快速、有效特点,在深部隐伏矿床找矿工作中发挥着越来越重要的作用,并取得了很好的找矿效果。研究区内曾开展过相关槽探、钻探工作,但无找矿突破。笔者在地质研究基础上,开展磁法、电法工作,最终在研究区内发现了有价值的矿致激电组合异常,推断是由铜镍矿化引起,并总结了该地区铜镍矿综合找矿模型;研究区发现了明显的地质、地球物理找矿标志,具有一定找矿前景。Abstract: In recent years,the geology explorations of metal mineral resources have been transferred gradually to deep concealed deposits.So,the integrated geophysical methods,in deep geological exploration of minerals as the important means,in deep hidden ore prospecting,characterized by economic,quick,and effective,play a more and more important role and have achieved good results.In the research area,some related studies such as trench exploration and drilling have been performed,but no prospecting breakthrough.The geological phenomena revealed that basic-ultrabasic rock is well developed in study area and the mineralization phenomenon is evident.Based on the geological study,we used the magnetic method and electrical prospecting in the study area,and finally found the valuable ore-caused anomalies,which is caused by copper and nickel ore body.
