摘要： 对国内外重力流研究的历程及现状，重力流形成的触发机制、沉积过程、发育序列等进行了综述，并重点分析了重力流划分模式、鉴定特征，以及在砂砾岩组合中可能发育的重力流类型。在此基础上，对准噶尔盆地玛湖斜坡区百口泉组砂砾岩发育特征及沉积组构进行了系统分析，认为主要发育泥石流、颗粒流、浊流、洪泛泥流和砂质碎屑流等5种重力流类型，结合典型钻孔岩性，总结出各类重力流鉴别标志，并建立了对应的沉积序列模式。

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
