| 摘 要： | 本文分析了扇三角洲各相砂体的基本特征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垂向地层序列牲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本、水下分流河道砂体及一些前缘砂体可能是赋武存可地浸砂岩铀矿的有利围岩。

| Abstract: | Like normal deltas, fan deltas are composed of three parts, i.e., fan delta plain, fan delta front and pre fan delta. In situ leachable uranium deposits are commonly distributed along the margins of in land basins. This paper analyzes the possible relationship between the basic characteristics of fan delta sandstone bodies and uranium mineralization. Two examples, e.g., the fan delta depositional systems in the eastern part of Jungger basin and the southern part of Yili basin, are given to illustrate the fan delta vertical sequence and planar distribution of sedimentary facies. It has been pointed out that the braided channel sandstone bodies on delta plain, subaqueous distributary channel sandstone bodies and delta front sandstone bodies may be the favouable host rocks for in sita leachable sandstone uranium deposits. |
