摘要
通过对研究区中侏罗统西山窑组下段砂体厚度和砂地比特征进行分析,结合室内普通薄片镜下鉴定,在此基础上绘制了乌库尔其铀矿床西山窑组下段沉积相展布图,探讨了砂体对铀成矿的控制与影响,指出了砂体连通性和均质性变化部位,为铀成矿的有利部位;同时认为扇三角洲前缘水下分流河道砂体及一些平原分流河道砂体是赋存可地浸砂岩型铀矿的有利围岩。
By studying area of the Middle Jurassic Xishanyao Formation of sand thickness and sand ratio characteristics of the analysis,the thin section identification,on the basis of drawing the distribution of sedimentary facies map of Wukuerqi uranium deposit,discusses the control and influence of sandbody on uranium mineralization,the sand body connectivity and homogeneousness change parts,favorable area for uranium mineralization; considers the fan delta subaqueous distributary channel sand body and some plain distributary channel sand body is favorable rock occurrence of in-situ leachable sandstone type uranium deposit.
