| 摘 要： | 鄂尔多斯盆地西缘HAB地区层间氧化带铀矿化的含矿层具有渗透性和铀源条件较好的灰色砂体,含有一定量有机炭作为还原剂、层间氧化带的规模和分带性都比较好。受层间氧化带翼部过渡带控制的铀矿化规模大、层数多、品位富,显示出本区具有很好的成矿潜力。建议今后将进一步控制延安组和直罗组层间氧化带前锋线的展布形态、追索矿体规模应为将来找矿工作的重点。

| Abstract: | The uranium mineralization bed in the interlayer oxidation zone in the HAB area on the western margin of the Ordos basin consists of gray sandstone, which has good permeability and uranium sources and contains a fair amount of organic carbon as the reducing agent. The interlayer oxidation zone has a certain extent and shows good zoning. Uranium mineralization controlled by the transition zone at the sides of the interlayer oxidation zone is characterized by a large extent, multiple beds and a high ore grade, showing good ore potential for the area. The authors suggest that the future mineral prospecting work should focus on further controlling the distribution shape of the front boundary of the interlayer oxidation zone of the Yan'an and Zhiluo formations and tracing the size of the orebody. |
