Project 2.1

2.1.1 Title: Formation and Modification of the Red River Submarine Fan and Links to the Episodic Uplift of the Tibetan Plateau

2.1.3 Project description:

This project aims to clarify the roles that the uplift of the Tibetan Plateau and the strike-slip motion of the Red River Fault Zone played in the formation of the Yinggehai-Qiongdongnan basin at the northwest corner of the South China Sea. We will construct the tectonic-stratigraphic framework of the Yinggehai-Qiongdongnan basin, and carry out U-Pb and fission track analyses on detrital zircons from the Oligocene-Pliocene strata (mainly in the Red River submarine fan). By comparing the dating results with age spectrum of zircons in the potential source areas, such as the Tibetan Plateau, eastern Vietnam and Hainan Island, we will identify the clastic sources of the Red River submarine fan, reveal the temporal and spatial evolution of the paleo-Red River, and discuss the tectonic-sedimentary response of the Yinggehai-Qiongdongnan basin to the episodic uplift of the Tibetan Plateau.

The Red River Fault
The Red River Fault links the Tibetan Plateau with the South China Sea. The southeast extrusion of the Tibetan Plateau is transmitted to the South China Sea by the Red River Fault, and impacted on the development of Red River submarine fan and even the formation of the Qiongdongnan-Yinggehai basin.
