The architectural patterns of sedimentary succession are diverse in different depositionalbasins. The sedimentary architecture and geological condition of such basins asepicontinental sea, intraplate limnic basins, etc., differ cIearly from those of continentalmargin basin. Extension, complement and perfection of sequence stratigraphic models are needed in the studies of various depositional basins based on the classical sequence model. This paper, for this reason,expounds the thought, principles of sequence division, methodology and technology of the study of sequence stratigraphy in epicontinental and limnic basins. 展开更多

In recent years, studies show that coal formed during marine transigression process is also important in coal accumulation basin. Still, the characteristics of coal formation is more clearly demonstrated by the coal formation in TST in the sequence stratigraphic framework. Based on the study of the characteristics of coal formation in epicontinental coal accumulation basin, the viewpoint that coal was formed under marine transgression was put forward by the authors and the mechenism thereof was also analyized. Marine transgression resulted in the forming of swamp and then the peat swamp. And the transgression later on put the peat formed in advance in deep water environment to form coal in the end. The important stratigraphic horrizons, such as coal seams, marine facies layers, formed with marine transgression are of the property of isochronism. 展开更多
