The Redox state of the asthenospheric mantle and the onset of melting beneath mid‐ocean ridges

F Zhang, S Lai, V Stagno, L Chen… - Journal of …, 2024 - Wiley Online Library
The redox state of the convective asthenospheric mantle governs the speciation of volatile
elements such as carbon and, therefore, influences the depth at which (redox) melting can …
