Based on the research of the gravity flow deposit characteristics in Banqiao- Beidagang area in Huanghua Depression, the characteristics of gravity flow deposit in the aspects of petrology, texture, structure and biology are detailedly described. According to the study of single well sedimentary section, the general development rule of turbidite is analyzed. Two types of sediment gravity flows are identified, which are deep water turbidite fan and gravity flow channel sediment. The sedimentary mirofacies and sedimentary assemblage are also analyzed, and the turbidite sedimentary sequence model is established. The environment characteristics for sediment gravity flow forming are discussed.
