How deep-Earth carbon movements shape continents and diamonds
A new study published in Science Advances by researchers from the Guangzhou Institute of Geochemistry of the Chinese Academy of Sciences (GIG-CAS), along with international collaborators, reveals that deeply subducted carbonates can cause significant variations in the redox states of Earth's mantle. This process influences the formation of sublithospheric diamonds and plays a role in the long-term evolution of cratons—ancient stable parts of the continental lithosphere.
