Sequence stratigraphy ＆ lithofacies palaeogeography in Qinshui Basin

Using the theory and methods of sequence stratigraphy and sedimentology,the sequence stratigraphy and lithofacies palaeogeography in Early PermianLate Carboniferous of the Qinshui Basin in Shanxi Province are studied on the basis of outcrops,well logging data and other geological information.According to sedimentary characters,several primary sedimentary facies are identified,such as carbonate platform,clastic shallow sea and delta.In this paper,coalbearing strata in the Qinshui Basin are divided into two sequences which consist of transgressive system tracts and highstand system tracts.Lowstand syetem tracts are not developed.The lithofacies palaeo-geography maps of each system tract are also plotted.
