The δ 13 C stratigraphic correlation between Dajiang and GSSP Meishan section suggest that the deposition from the skeletal packstone to the overlying microbialite at Dajiang may be not continuous (Figures 2, 5).along the shelf margin. They include skeletal packstone at the base which grades up-ward to ooid-oncoid grainstone, and finally into ooid grainstone (Tye and Moore, 1986). A relative sea-level fall at the end of “A” sequence deposition exposed the Smack-over platform to meteoric processes. The overlying Buckner sequence was deposited as

Most parasequences are made up of basal skeletal-peloid wackestone-packstone that grades up into a thick skeletal packstone-grainstone (Fig. 9 F), capped by a thin microbial or fenestral laminite. The parasequences in the 300-m-thick Oxfordian-basal Kimmeridgian part of the DJ section are dominated by mud-supported facies and vary widely in ...The mound capping facies include a lower skeletal packstone–wackestone and an upper lagoon facies marlstone and black shale. Various algal colonies performed different roles in the formation of the mound. Komia colonies were the mound constructors that baffled higher energy currents and entrapped fine sediment. ….
