In this paper, through the analyses of sedimentary rock assemblages, structures and logging traces of twelve wells respectively from the north, east and south margins of the Junggar Basin, have been studied for classification, correlation and sequence stratigraphic framework of Jurassic Uraniumbearing Series. All researches indicate that the sequence stratigraphy have big differences in different positions. The sequence from Sangonghe Formation to Qigu Formation on the north margin of the Junggar Basin is three, including seven system tracts. The sequence from Badaowan Formation to Qigu Formation on the east margin of Junggar Basin is five, including twelve system tracts. And the sequence from Xishanyao Formation to Qigu Formation on the south margin of Junggar Basin is three, including seven system tracts. During the Badaowan and Qigu period, it had at least two lake formation. The whole experiences the process of retrogradation, progradation and then retrogradation again. Alluvial sand bodies of braided stream and delta fan are the main uranium reservoir. And the delta fan on the north margin also indicates uplifting events. The Jurassic in the study area mainly developed five kainds of deposition types, which are braided, braided viver deltas, lakes, lake deltas and delta fan, ten kinds of sedimentary subfacies types. The subfacies types of uraniumbearing series are braided channel, fan and lake delta plain. There were two parallel unconformities respectively up and under the coal bearing formation of Xishanyao period. The clay ground under the unconformaities have formed stratigraphic trap, the sand bodies on the two sides of the unconformaities are the most favorable exploration targets in the Junggar Basin. All the above results not only provide new constraints on increasing the precision of classification and correlation of Jurassic Uraniumbearing Series in the Junggar Basin, but also have great significance on the exploration of sand type uranium.
