摘　　要：对吐哈盆地的构造演化、构造特征及十红滩砂岩型铀矿特征进行综合研究,认为构造对艾丁湖斜坡带上十红滩可地浸砂岩型铀矿的控制可分为3个层次:构造演化控制了铀源、找矿目的层的沉积建造类型及铀矿化期次;斜坡构造单元控制了铀矿化区;斜坡带构造带上的次级构造控制了铀矿体的分布。Through studying the structural evolution, structural characteristics of Shihongtan sandstonetype uranium deposit, it is found that there are three types of structural controls on Shihongtan sandstone-type uranium deposit on the Aiding structural slope, namely, the uranium sources, types of the sedimentary formation of target horizons and the mineralization epochs are controlled by the structural evolution of the basin; the mineralization area are controlled by the structural slope units; the distribution of uranium ore bodies is controlled by the second order structures on the structural slope.
