砂岩型铀矿是当前我国铀矿勘查的战略重点。江汉盆地砂岩型铀矿找矿工作程度低。以江汉盆地西北缘宜昌-当阳一带为研究区，综合利用Sentinel-2、Landsat8、ASTER GDEM等数据，开展纹理增强、三维可视化建模、蚀变信息提取等工作，对区内已知铀矿化点成矿要素和成矿条件进行识别与分析。结果表明：研究区西北部含铀酸性侵入岩具备良好的铀源特征；侵入岩周边往盆地方向发育的斜坡带为含铀含氧水迁移创造有利条件；发育的断裂构造为含铀含氧水向地下迁移提供了通道；白垩纪地层具备的泥-砂-泥结构成为重要的容矿空间，其发育的铁染信息是后生氧化作用重要的指示标志，也说明该地区砂岩型铀矿具有较典型的层间氧化带特征。基于多源遥感识别的成矿要素与成矿条件，利用网格法预测4处I级有利区，其中3处与已知铀矿化点吻合良好，另1处具备较好的地层、斜坡和断裂条件，可作为后续铀矿勘查的重点方向之一。
Abstract：Sandstone-type uranium deposits are currently a strategic focus in uranium exploration in China. The prospecting for sandstone-type uranium deposits in the Jianghan Basin has long lagged behind，and no significant breakthroughs achieved. This study focuses on the Yichang-Dangyang area along the northwestern margin of the Jianghan Basin. Using data from Sentinel-2，Landsat 8，ASTER GDEM，and other sources，we conducted texture enhancement，three-dimensional visualization modeling，and alteration information extraction to identify and analyze the metallogenic factors and conditions of known uranium mineralization points. The results indicate that the uranium-bearing acidic intrusive rocks in the northwestern part of the study area exhibit favorable uranium source characteristics. The slope zone extending from the periphery of the intrusive rocks toward the basin provides conducive conditions for the migration of uranous-oxygenic water. The fault structures developed on the slope zone serve as pathways for the downward migration of uranous-oxygenic water. The mud-sand-mud structure present in the Cretaceous strata on the slope zone constitutes a significant ore-hosting space，while the iron staining information developed within it serves as an important indicator of epigenetic oxidation. This also suggests that the sandstone-type uranium deposits in the region exhibit typical interlayer oxidation zone characteristics. Based on the metallogenic factors and conditions identified through multi-source remote sensing，a grid-based method was employed to predict favorable areas. Four Class I favorable areas were identified，three of which show good correspondence with known uranium deposits (points). The remaining area exhibits favorable stratigraphic，slope，and fault conditions and can be considered as the key direction for future uranium exploration.
