摘要
内蒙古中部地区发育有较多的中新生代山间盆地 ,但可地浸砂岩型铀矿地质工作目前还是空白。本文通过对前人地质、物探、水文地质资料的综合分析研究 ,认为本区具备有利于含氧含铀水长期稳定运移并富集成矿的地质构造和沉积环境 ,但是 ,不同的次级构造单元、盆地的演化特征仍有所差异 ,其找矿目标层位、找矿类型和成矿前景也有所不同。
Numerous Mezo Cenozoic intramontane basins are developed in the central region of Inner Mongolia. But, little work has been done in prospecting for in situ leachable sandstone type uranium deposits. Based on the study and comprehensive analysis of preexisting geological, geophysical and hydrogeological data, authors of this paper suggest that the study area possesses basic geologic tectonic conditions and sedimentary environment favourable for the long term and stable migration of oxygen bearing uranium bearing ground water and for the uranium ore concentration. However, certain difference exists in the basin evaluation of difference tectonic units. As a result, the prospecting target horizon, target mineralization type and metallogenic prospect in different basins should be different from each other.
