摘要

Detailed sedimentary facies analysis and sequence stratigraphic division of the four measured sections and one well log section are studied on the basis of principles and methods of sedimentology and sequence stratigraphy. The patterns of sedimentary facies transformation, types of sequence boundaries, sequence characteristics and their dominating factors are described as well. It shows that the upper Triassic of the northern mid-Yangtze Basin can be divided into four third-order sequences (TS1, TS2, TS3 and TS4); and further grouped into one second-order tectonic sequence. The thickness of the Upper Triassic is about 1 200 m in Jingmen-Dangyang Basin where the four sequences are relatively intact.
