The global consequences of subduction zone congestion

The project is a combination of 3D geodynamic modelling, plate kinematic reconstruction and geological and geophysical synthesis that will determine how congested subduction zones influence plate kinematics, subduction dynamics, and tectonic evolution at orogen and global scales. We will deliver a transformation change in understanding the links between congested subduction, mantle flow, trench migration, crustal growth, transitions between stable convergent margin configurations, and deformation in the overriding plates of subduction zones. Determining these relationships is significant because it will provide dynamic context to interpret the geological record of ancient convergent margins, which host a large percentage of Earth's metal resources.
