根据水成铀矿理论及其找矿实践经验,典型层间氧化带砂岩型铀矿一般只产出于中新生代以来构造相对稳定的次造山带构造区(张金带等,2005),具有缓倾斜坡带的中新生代盆地,而构造活动相对强烈的断陷或冲断带特征的盆地边缘不利于层间氧化带砂岩型铀矿形成。但通过对鄂尔多斯盆地西缘断褶带发展演化,尤其是侏罗纪以来盆地构造变动及改造特征的深入分析,认识到在鄂尔多斯盆地西缘断褶带内,存在相对和缓的构造活动时期及构造活动相对稳定的区段。综合分析该区段地质构造环境及其演化,结合该地区油、气、煤等矿产及其对砂岩型铀成矿的影响,预测其中的惠安堡地段具有良好的铀成
Based on the theory of hydrothermal uranium deposit and its prospecting experience, the typical interlayer oxidation zone sandstone-type uranium deposits are generally only produced in the relatively stable sub-orogenic belt since the Meso-Cenozoic (Zhang et al., 2005) In the middle-Cenozoic basins of gentle-dip slopes, the margin of basin characterized by faulting or thrusting with relatively strong tectonic activity is not conducive to the formation of interlayer oxidation zone sandstone-type uranium deposits. However, through the deep analysis of the evolution and development of the fold belt in the western margin of the Ordos Basin, especially the structural changes and the characteristics of the alteration of the basin since the Jurassic, it is recognized that there are relatively gentle tectonic activities and tectonics in the fault zone in the western margin of the Ordos Basin Relatively stable activity section. Based on a comprehensive analysis of the geological tectonic environment and its evolution in this section, combining with the mineral resources in the area such as oil, gas and coal and their effects on the mineralization of sandstone-type uranium, it is predicted that there is a good uranium content
