Title: STUDY ON ALLUVIAL-FLUVIAL FACIES SEQUENCE STRATIGRAPHY
Abstract: The principles of sedimentology and sequence stratigraphy were used to research the mode of sequence stratum of coastal alluvial environment. An universal mode for sequence stratum of alluvial-fluvial facies was established. The relationship between system tract and sedimentary facices was discussed on the analysis of river types of the Neogene in Jiyang Depression. The results show that there are four types of system tracts in alluvial-fluvial facies including low system tract, extension system tract, high system tract, contracting system tract. According to the sedimentary characteristics of the Neogene in Jiyang Depression, the types of sediment system and facies corresponding to the different system tracts were given. There were alluvial-braided river facies in low system tract. The braided river was transited to meandering river in extension system tract. There was meandering river in the high system tract, and the meandering river was transited to braided river in the contracting system tract.
