本文分析了扇三角洲各相砂体的基本特征及其与铀矿化的可能关系，以两个实例探讨了准噶尔盆地东部大庆沟侏罗系扇三角洲的垂向地层序列特征和伊犁盆地南部侏罗系水溪沟群扇三角洲垂向序列和平面岩相分布特征，指出了扇三角洲平原辫状河道砂体、水下分流河道砂体及一些前缘砂体可能是赋存可地浸砂岩型铀矿的有利围岩。
This paper analyzes the basic characteristics of the sand bodies in fan facies and their possible relationship with uranium mineralization. The paper discusses the vertical stratigraphic sequence of the Jurassic fan delta in Daqinggou in eastern Junggar Basin and the Jurassic It is pointed out that the fan delta plain braided channel sand bodies, underwater distributary channel sand bodies and some of the front sand bodies may be hosted exinitely leachable sandstone-type uranium Beneficial rock of the mine.
