摘　　要：十红滩铀矿床南矿带位于吐哈盆地西南缘,该矿带的含矿层位为侏罗系西山窑组第一岩性段,段内砂体可分为上、下两层。通过对区内钻孔含矿砂体厚度及其底板海拔高度进行统计,绘制了砂体等厚图并详细分析了十红滩铀矿床南矿带西山窑组第一岩性段(J2x1)含矿砂体的空间展布特征,划分了5条主要辫状河河道。将上述图件与矿体形态进行综合分析,发现矿体与辫状河河道紧密相关,并受砂体底板和后期构造控制。The southern ore belt of Shihongtan uranium deposit is located at the southwest of Turpan Basin,the ore-bearing strata of the ore belt is the first lithologic segment of Xishanyao Formation of Jurassic,the sandbody of the lithologic segment can be divided into the upper and lower layers. Based on the statistical results of the thickness and floor evaluation of ore-bearing sandbody,the equal thickness map of sandbody is drawn,and the spatial distribution characteristics of the ore-bearing sandboy in the first lithologic segment of Xishanyao Formation of Jurassic in the southern ore belt of Shihongtan uranium deposit is analyzed in detail,besides that,five braided rivers are confirmed. The comprehensive analysis of the equal thickness of sandbody and ore-body shapes show that,the ore-body is closely reated to the braided rivers,and controlled by sandbody floor and later structural movement.
