摘要: 分析昭苏盆地砂岩型铀矿成矿潜力,为伊犁盆地提供后备矿产基地。以近年来在昭苏 盆地开展的铀矿地质调查为基础,以构造、岩性岩相、层间氧化带等砂岩型铀矿控矿因素为研究内 容,分析评价了昭苏盆地砂岩型铀矿成矿条件。研究表明,昭苏盆地构造活动较强,但在构造活动地 区存在相对稳定地段,具备形成层间氧化带砂岩型铀矿床成矿条件;含矿建造侏罗系广泛发育,分布 在阿登套山以北的盆地北部坳陷带,侏罗系西山窑组、头屯河组砂体和层间氧化带较为发育,且发现 有丘拉克梅斯等铀矿化或铀异常点。阿登套山北侧以及乌宗布拉克北部山前地段发育砂体、层间氧 化带和铀矿化且埋深相对较浅的,可作为下一步探索评价工作的优选地段。

Abstract: The metallogenic potential of sandstone-type uranium deposits in Zhaosu Basin is analyzed to provide a reserve mineral base for Yili Basin. Based on the geological survey of uranium deposits in Zhao⁃ su Basin in recent years,the ore-controlling factors of sandstone-type uranium deposits such as structure, lithology,lithofacies and interlayer oxidation zone are studied,and the metallogenic conditions of sand⁃ stone-type uranium deposits in Zhaosu Basin are analyzed and evaluated. The research shows that the tec⁃ tonic activity of Zhaosu Basin is strong,but there is a relatively stable area in the tectonic activity area, which has the metallogenic conditions of forming interlayer oxidation zone sandstone type uranium deposit. The Jurassic ore-bearing formation is widely developed and distributed in the northern depression zone of the basin to the north of the Adentao Mountain. The Jurassic Xishanyao Formation and Toutunhe Formation sand bodies and interlayer oxidation zones are more developed,and uranium mineralization or uranium anomalies such as Qiulakemeisi are found. The sand body,interlayer oxidation zone and uranium mineraliza⁃ tion are developed in the northern side of the Adentao Mountain and the piedmont area of the northern Wu⁃ zongbulake,and the burial depth is relatively shallow,which can be used as the preferred area for the next exploration and evaluation work.
