Abstract：There are different viewpoints about the sedimentary facies of the Middle Jurassic Toutunhe Formation in Shinan area of Junggar Basin by far. Based on detailed core observations,thin sections and logging analysis,through study on sedimentary characteristics of lithologic types,sedimentary structures and sedimentary sequence was carried out. Combining with regional sedimentary background and tectonic setting,we considered that the sedimentary environment of the Toutunhe Formation in Shinan area is braided delta. Braided delta front sediments were deposited during the depositional period of Member 1 of Toutunhe Formation,the ribboned sandbody of subaqueous distributary channel widely developed. During the depositional period of Member 2 of Toutunhe Formation,braided delta system progradated,braided delta plain appeared at areas close to provenance and sandbodies of braided delta plain were overlapping and widely distributed. During the depositional period of Member 3 of Toutunhe Formation, the lake level rised rapidly,and shallow lake facies were mainly developed in the study area.
