摘　　要：在前人研究工作的基础上,从遥感地质的角度对钱家店铀矿区进行了再认识。发现钱家店铀矿区在褶皱抬升之后,发生了断块隆起,形成断隆构造,控制了本区的铀成矿后生改造和多期成矿作用。认为钱家店铀矿区的成矿演化,经历了断陷→坳陷→褶皱抬升→断块隆起几个阶段,提出本区的构造反转成矿不限于前人认为的褶皱抬升和断层上下的反向错动,更具成矿意义的是断陷向断隆的构造反转。依据上述认识,探讨了开鲁坳陷进一步区域找铀矿的新思路和遥感地质的具体做法。Based on previous studies, this research carried out geological structure analysis for the Qianjiadian uranium deposit with remote sensing technology. The faulted uplift followed the folded uplift was believed to contribute to the later multi -stage uranium mineralization in the area. This research proposed that Qianjiandian uranium deposit underwent the tectonic state of fault depression, depression, folded uplift, and faulted uplift. The reversed structure in the Qianjiadian area as proposed by previous literature should not limited to folded uplift and fault relative motion, but also the faulted uplift after the fold uplift. On the basis of the new analysis result, the research discussed the ore exploration strategy for the Kailu depression.
