Geochemical Perspectives Letters: Redox state of the convective mantle from CO2-trace element systematics of oceanic basalts
Redox state of the convective mantle from CO2-trace element systematics of oceanic basalts By: James Eguchi, Rajdeep Dasgupta Abstract: The redox state of mantle lithologies, based on xenoliths from continental lithospheric mantle, has been shown to decrease with depth and reach oxygen fugacities (fO2) at which graphite/diamond will be the stable form of carbon at […]
