摘要
湘鄂赣二叠纪沉积盆地是在华南陆块基础上发育而成，具有扬子克拉通北缘被动大陆边缘盆地、扬子克拉通盆地、湘赣板内拉张盆地和华夏克拉通边缘盆地等四类。根据古暴露等标志，建立了各类盆地的沉积层序，并进行了区域对比。在此基础上，本文着重运用层序地层编图法编制了湘鄂赣二叠纪岩相古地理图，深化了该区岩相古地理研究，详细建立了沉积体系域模式和岩相古地理演化特点和控制因素。
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.
