Abstract: A major breakthrough of thick bedded sandstone oil and gas exploration is in China's western Xinjiang region of Jurassic and Cretaceous. Large areas of thick layer of sand body and red mudstone layer deposition formation mechanism have been a research focus by attention for a long time. Combined with much more information including southern margin of Junggar Basin sedimentary system of seasonal rivers, sand body distribution characteristics of analysis, and analysis of the lithofacies assemblages and rock color, sedimentary structure and formation mechanism of sandstone and mudstone of the Haojiagou-Toutun River section and Manasi River section of Toutun River formation of Middle Jurassic in upper part of Middle Jurassic Qigu and Kalazha Formation in the southern margin of the Junggar Basin, We think arid climate background ephemeral streams are the main sediment types of the period. An ephemeral streams sand body configuration and the genetic model have been established, and further understanding of ancient ephemeral streams sedimentary will provide the beneficial reference in China.
