Abstract: The Permian sedimentary basins in the Hunan-Hubei-Jiangxi region are developed on the ground of the unified South China continental block.According to crustal activity,sedi-ment filling sequences,sedimentary facies belts and their spatial arrangement,the sedimen-tary basins in this region may be divided into Yangtze cratonic basin,passive marginal basin on the northern margin of the Yangtze craton,Hunan-Jiangxi intraplate extensional basin and Cathaysian pericratonic basin.The differences of the controlling factors and asso-ciated effects upon the sequence development are responsible for the differences of se-quence development.The present paper deals in details with the genesis and characteristics of the depositional sequences and depositional systems tracts in various sedimentary basins in the study area,and the regional correlations are also made in this paper.
