Abstract: The history and actuality of gravity flows researches at home and abroad were reviewed, including the gravity flow formation mechanism, sedimentary process and development sequence, etc., and the classification models and identification characteristics of gravity flows were analyzed, pointing out the possible gravity flow types in glutenite combination. Based on these results, the development characteristics and depositional fabrics of Baikouquan glutenite in Mahu slope area of Junggar basin were systematically observed and studied. It is suggested that five types of gravity flows, such as debris flow, grain flow turbidity current, flood mudflow and sandy debris flow, are mainly developed in the Baikouquan formation. According to the typical cores lithology descriptions, the identification marks for various gravity flows are presented, and the corresponding sedimentary sequence models are established in this paper
