摘要
通过对四川盆地大地构造位置、地貌—气候、盆地盖层的岩性—岩相、水文地质条件等方面分析,认为四川盆地具备可地浸砂岩型铀矿的区域成矿条件。指出找矿有利地区是盆地中部构造稳定区与活动区过渡的大型单斜地区和盆地南部宽缓向斜地区。找矿目的层是上三叠统和下、中侏罗统的疏松砂岩层。
Research on geotectonic setting, geomorphology - climate, lithology and lithofacies of the cover and hydrogeological conditions indicates that ore - forming conditions of in - situ leachable sandstone - type uranium deposits come into existence in the Sichuan basin. Large monoclinal structure areas in intermediate zone between tectonically stable and active areas in the central basin and broad synclinal areas are favourable to the ore - formation of the sandstone - type deposits. The Upper Triassic, Lower and Middle Jurassic loose sandstone are potential ore- bearing beds.
