| 摘 要： | 本文从雅布赖盆地原型盆地特征与构造改造作用出发，分析了盆地砂岩型铀矿成矿目的层沉积体系的展布特征和后期改造作用，结合砂岩型铀矿成矿的预测准则，认为雅布赖盆地后期构造改造强烈，总体成矿前景不佳，但位于盆地中部、由北向南展布的古斜坡带下白垩统仍存在一定的成矿前景。

| Abstract: | Based on characteristics of initial basin type and tectonic reworking process,th is article analyses the distribution features of depositional system and subsequ ent alteration of the target horizon of sandstone-type uranium deposits in Yabu lai basin.Guided by prognostic criteria of sandstone-type uranium deposits,auth ors suggest that the post-depositional tectonic reworking in the basin was quit e intense,and uranium metallogenic prospects are unfavorable.However,the Lower C retaceous in the paleo-slope at the middle of the basin does show certain metal logenic prospects for sandstone-type uranium deposits. |
