Tectonic Subsidence Calculation Based on Seismic Data

The reconstruction of subsidence history of is very important in basin modeling and basin analyses. Tectonic subsidence can reflect the tectonic activity, which was calculated based on burial history. Through quantitative basin modeling research of tectonic subsidence history of deep water area in Pearl River Mouth Basin, tectonic subsidence has been generally characterized by acceleration from north to south and from west to east in the research area since the Late Miocene. Dongsha tectonic event from the end of the Middle Miocene to the end of the Late Miocene and Taiwan tectonic event from the Pliocene to the Early Pleistocene was considered the possible major resons.
