摘要

///The Daxiakou section in Xingshan, Hubei characterized by a complete development of the Lower Triassic, clear boundaries, favorable exposure and good development of sedimentary structure is an ideal section for the study of the Lower Triassic in west Hubei Province. The research shows that open platform, restricted platform, open continental shelf, slope, shoal and other environment can be identified in the Early Triassic. The vertical evolution of sedimentary facies is open continental shelf-slope-platform, the whole process is sea level drop and shallow water, with occasional and short time sea level rise. A sedimentary model of open continental shelf-slope-open platform-shoal- restricted platform for the Lower Triassic in the Daxiakou section is established on the basis of lithology and sedimentary environment.
