新疆十红滩铀矿床含矿目的层物质来源及其构造背景分析:来自岩石学和地球化学的证据
|
摘要
十红滩铀矿床位于中国新疆吐哈盆地西南缘艾丁湖斜坡,是典型的层间氧化带型铀矿床,西山窑组为最重要含矿目的层之一。明确其岩石学和地球化学特征,对于盆地找矿和地浸采铀均十分重要。通过对矿区西山窑组碎屑岩岩石学研究、微量元素和稀土元素测试分析,可知西山窑组碎屑岩成分成熟度和结构成熟度均较低,以岩屑砂岩为主,为近物源沉积产物;母岩经历了较强风化作用,其成分特征与上地壳相似,轻稀土富集,重稀土较平坦,铕亏损较明显,物源主要来源于上地壳长英质岩石,母岩沉积构造背景为活动大陆边缘岛弧相关的沉积盆地。
The Shihongtan uranium deposit is located in the southwestern margin of the Tuha Basin in Xinjiang.it is one of typical interlayer-oxidation type uranium deposits,and the Xishanyao formation is one of the most important ore-bearing target layers. It is very important to the mining and in-situ uranium mining by identifying their petrological and geochemical characteristics. Through the petrology study,trace elements and rare earth elements of the Xishanyao formation in this study area,it is shown that the composition maturity and structural maturity of clastic rocks are low,mainly with lithic sandstone,which belongs to a near-physical sedimentary product. The provenance rocks has experienced strong weathering,and its composition is similar to those from the upper crust,light rare earth enrichment,heavy rare earth is relatively flat,and the Eu loss is obvious. The source is mainly derived from the upper crust felsic rock,and the sedimentary tectonic background is associated with continental island arcs of sedimentary basin.
