Abstract

Abstract

The carbonate ramp, characterized by the wide sedimentary facies, is short of visual physical markers of the sequence surface. But the multi-scale lithological cycles caused by the fluctuation of regional climate-sea level are well developed, which are strong in regional correlation and abundant in fossils. Therefore, the regional outcrop sequence stratigraphy can be well studied in the light of the application of cyclostratigraphy and ecostratigraphy. The stacking patterns of the lithological cycles, i.e. parasequences, and the migration of the habitat types show that the Lower Triassic sequences are properly identified, on the outcrops in the Lower Yangtze region, for the establishment of the sequence stratigraphic framework. In addition, the transgressive surface can be used to define the third-order sequences in the outcrop sequence stratigraphy on carbonate ramp, which are more understandable and practical.
