Deep fluid activity is closely related to carbonate reservoir transformation as well as oil and gas accumulation. The large-scale deep fluid activity caused by Emeishan large igneous province (ELIP) brought a lot of deep material and energy to Sichuan Basin and changed the paleogeothermal and geochemical field of the region they flowed through, which had an important impact on the formation of ...These Limestone Accumulation calcified plankton substantially increased deep-water Broad correspondence between measured accumu- carbonate accumulation (Hay, 1985; Opdyke and lation rate of shallow marine limestones (Bosscher and Wilkinson, 1988) at the expense of shelf carbonates Schlager, 1993) and calculated saturation state over the ...

A unit is a distinct layer of rock with the same composition. The first unit is a thin transgressive marine limestone. The second is a thin, offshore black shale, the third unit is a thicker shallowing-upward regressive limestone.Chert is an amorphous hydrous silica that is characteristic of deep marine depositional environments. If Radiolaria are visible as white dots in the chert, it is known as Radiolarian chert. Small layers of carbonates are sometimes found in deep marine chert as a result of turbidites from carbonate platforms.
