The global consequences of subduction zone congestion

该项目将综合使用三维地球动力学建模、板块运动学重建以及地质和地球物理综合，以确定密集俯冲带如何影响造山带和全球范围的板块运动学、俯冲动力学和构造演化。该项目的目的是提供一个转型的变化，了解拥挤的俯冲，地幔流动，海沟迁移，地壳生长，稳定的收敛边缘配置之间的过渡和俯冲带覆盖板块的变形之间的联系。确定这些关系是重要的，因为它将提供动态的背景下，解释地质记录的古代收敛边缘，其中主机的很大一部分地球的金属资源。

This project 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. The project aims to 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.
