摘　　要：为适应新时代铀矿勘查的发展需要,有必要对近二十年来我国北方中新生代沉积盆地中可控源音频大地电磁法(CSAMT)勘查成果及存在问题进行总结,旨在进一步提升方法应用效果,以期更加高效地为我国“十四五”期间的铀资源勘查战略服务。文章介绍了“十五”初期至“十三五”期末我国北方盆地铀资源评价中CSAMT法勘查进展,重点分析了方法探测目标任务的理论模型,总结了方法勘查取得的主要成果,指出了尚存在的一些问题与不足,提出了应对策略。展望“十四五”,我国铀矿地质勘查工作面临的任务将更加艰巨,特别是随着铀矿找矿工作向深部“第二空间”不断深入,CSAMT作为相对经济、快速、有效的大探测深度勘查技术方法,必将得到进一步的应用和发展。To meet the development needs of uranium exploration in the 14th five-year plan,it is necessary to summarize the exploration results and founding the problems of CSAMT application in Mesozoic-Cenozoic sedimentary basins of northern China in recent 20 years.This paper introduces the exploration progress of CSAMT method in the evaluation of uranium resources in northern basins of China from the beginning of the 10th five-year plan to the end of the 13th five-year plan.The theoretical model of target detection task is analyzed emphatically,the main achievements of method were summarized too.The authors pointed out some existing problems and shortcomings,and put forward some countermeasures.The uranium exploration task in China will be more arduous,especially with the deepening of uranium prospecting to the deep“second space”,CSAMT method as a relatively economic,fast and effective exploration technology with large exploration depth,will be further applied and developed.
