  • Study on the Permian Sequence Stratigraphy of the Youjiang Basin reveals that gravity flow develops during every period of eustatic cycles and it displays individual characteristic internal configuration and genetic framework of sequences.Lowstand is characterized by basin margin-downslope miscellaneous lithic turbidites,and gravity flow is relatively less in shelf marginal systems.During transgressive periods,gravity flow is dominated by calcarenaceous clastic flow and its recomposed sand deposit.The deposit of gravity flow in highstand has large thickness,wide distribution and rich genetic patterns,and is mainly characterized by well-developed calcarenaceous colluvial rocks,grain flow,liquefied sediment flow,clastic flow,and turbidity flow.
