| 摘 要： | 本文运用层序地层学理论和工作方法，对吐鲁番-哈密盆地南缘诛罗系地层进行了详细研究，识别出3个Ｉ类层序，分别与岩石地层单位八道湾组、三工河组、西山窑组大致相当；在层序体系域、沉积体系研究的基础上，指出层序内高水位体系域（HST）中的辫状河三角洲体系是层间氧化带砂岩型铀矿产出的有利层位。

| Abstract: | Based on the theory of sequence stratigraphy,the sequence features of the Jurassic at the southern margin of Tulufan-Hami Basin have been analyzed and three type of I sequences have been identificated approximately corresponding to Badaowan,Sangonghe and Xishanyao Formations respectively. Having thoroughly studied the depositional system tract and depositional system of these sequences, the authors propose that braided delta depositional system within highstand system tract(HST) is favourable for the formation of sandstone type uranium deposits in interlayer oxidation zone. |
