Theme 3: Global Palaeogeography and Geodynamics

Theme Co-leaders: Dietmar Müller (Australia), Hanlin Chen (China)

Project 3.2

3.2.1 Title: East Asian Continental Margin and Subduction Retreat

3.2.2 Leader(s) from different ACTER partner institutions:

3.2.3 Project description:

The West Pacific is characterized by a unique and complete trench-arc-basin system with the deepest trench. In this project we aim to understand the formation and evolution history of the West Pacific system, its basic architecture, modification of the continental margin by the subduction process, and the dynamic driving mechanism.
