Doctoral Dissertations

“This study is carried out in Minfeng area, the steep margin of Dongying half graben, eastern China, by integrating 3-D seismic, wireline log, and core data, and aims to interpret the depositional systems, reconstruct sequence stratigraphic architecture, and understand the controlling processes and factors at the steep margin of a rift basin. In the first part of this work, an Eocene stratigraphic sequence is divided into three systems tracts, corresponding to different stages of lake evolution, as early expansion (EEST), late expansion-early contraction (LEECST), and late contraction (LCST). EEST is the thickest and diagnostic by the best-developed marginal and basinal …
