The link between cratonic roots, redox state, and mantle geodynamics.

本项目旨在了解地球氧化还原状态在大陆克拉通根地球动力学演化中的作用。克拉通根形成坚固、浮力强的木筏，澳大利亚最古老的地壳和矿藏就在木筏上存活下来。克拉通保存了行星尺度化学变化的记录，包括地表氧气的增加，但尚不清楚这些氧化还原变化本身是如何影响岩石圈过程的。该项目整合了地球化学、地球物理学和地球动力学的新发展，绘制了克拉通根的地球化学状态和结构，有助于矿产勘探，并阐明了克拉通根的改造、矿化和有时破坏的过程。

This project aims to understand the role of Earth's redox state on the geodynamic evolution of continental cratonic roots. Cratonic roots form strong, buoyant rafts upon which Australia's oldest crust and mineral deposits survived. Cratons preserve a record of planetary-scale chemical shifts, including the rise of surface oxygen, but it is unclear how these redox shifts themselves affected lithospheric processes. This project integrates new developments in geochemistry, geophysics, and geodynamics, to map the geochemical state and structure of cratonic roots, aiding mineral exploration, and also shedding light on the processes that modify, mineralise, and sometimes destroy cratonic roots.
