摘要: 吐哈盆地十红滩铀矿床属层间氧化带砂岩型铀矿床，赋存于中侏罗统西山窑组含煤碎屑岩中。容矿层岩石中富含有机质，有机碳、可溶有机物、酸解吸附烃在不同地球化学分带的岩石中含量大小不同，尤以矿石带含量最高。矿石有机质母质类型为腐殖型，处于未成熟演化阶段，酸解吸附烃为煤成气型。统计计算表明：容矿层中铀和可溶有机物、酸解吸附烃含量之间具明显的相关关系。分析了有机质在砂岩型铀矿床形成过程中的作用，认为容矿层中有机质在含氧环境下分解的产物利于铀在水中的溶解和迁移，而在缺氧条件下分解的产物，构成铀沉淀的还原和吸附地球化学障，在铀的成矿过程中发挥重要的作用。

Abstract: The Shihongtan uranium deposit in TurpanHami basin is an interlayer oxidized zone type sandstone uranium deposit, which occurs in the coalbearing detrital rocks of braided meandering stream facies in the Middle Jurassic Xishanyao Formation. There is a great deal of organic matter in the orehosting bed. There is distinct content of organic carbon, soluble organic matter, acidolysis hydrocarbon in various geochemistry belt rocks, and the maximum content in the ore belt. Organics carbon mothermaterial type is sapropelic humus, organic matter is under mature stage. Acidolysis hydrocarbon is coalgas type. Uranium content in rock is positively correlative to soluble organics and acidolysis hydrocarbon by statistical count. The paper analyzed the role of organic matter in sandstone type uranium metallogenetic process, and concluded that the material decomposed under oxygenic condition is advantageous to uranium dissolution and migration in groundwater, material decomposed and polymerized under oxygendeficient condition forms reducing and adsorption geochemistry barrier for uranium precipitation, play an important role in uranium metallogenetic process.
