The global consequences of subduction zone congestion

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