Project Description

We will use a combination of 3D geodynamic modelling, plate kinematic reconstruction and geological and
geophysical synthesis to 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.
