PERMIAN SEDIMENTARY FACIES AND PALAEOGEOGRAPHY IN THE HUNAN-HUBEI-JIANGXI REGION

The Permian sedimentary basins in the Hunan-Hubei-Jiangxi region developed on the South China continental block are classified into the passive marginal basin on the northern margin of the Yangtze craton,Yangtze craton basin,Hunan-Hubei-Jiangxi intraplate exten-sional basin and Hercynian pericratonic basin.The sedimentary sequences in individual basins have been established and correlated regionally in the light of fossil exposures. Moreover the sedimentary facies and palaogeographic maps of the Hunan-Hubei-Jiangxi re-gion have been worked out,and models for the depositional systems tracts proposed in the present paper.
