In recent years, we have conducted studies on the chemostratigraphy and biostratigraphy of the SDB sequences in the Xishancun Section (Qujing area in Yunnan Province), Putonggou Section (West Qinling area in Sichuan Province) and Changwantang Section (Yulin area in Guangxi Province) for pinpointing the SDB within different sedimentary facies in the South China Block (Fig.

Paleostructure controlled the development of basins and distribution of sedimentary facies, which further influenced the depocenter of oil shale and the center of the prolific zone.
His main focus is on the evolution of sedimentary basins from sedimentary facies to plate tectonics.
In the lacustrian and delta sedimental system, when the sediments reach the certain ratio, the ascent of the lacus water level will lead to the deepen upwards of the sedimentary facies sequences and the thin of the sedimentary grain.
As part of this project, GXT has also been requested to undertake advanced geophysical and reservoir analyses that build upon the acquired seismic data, such as determining reservoir porosity and permeability, evaluating gas saturation, and mapping sedimentary facies and sequence stratigraphy.
From a hydrographical point of view, it appears that the confluence has undergone changes in riverine/lacustrine flow regime which are represented by the deposition of a complex suite of sedimentary facies ranging from imbricated gravel-dominated open channel facies, through to fine grained and organic-rich lacustrine and slackwater deposits.
This begins with a comprehensive description of the stratigraphy and sedimentary facies, using modern analogues, followed by a discussion of parasequences, sequences and systems tracts.
Despite the interest in Zagros folds due to their major hydrocarbon reserves, and after extensive drilling by oil companies, geophysical and geological surveys, little has been published about the structural behavior of the sedimentary cover, the structural style and its relationship with sedimentary facies and evolution of the belt since the Late Cretaceous.
