Deep mantle carbon flow influences diamond formation and craton stability

Tokyo, Japan (SPX) May 22, 2025

A recent study led by scientists at the Guangzhou Institute of Geochemistry of the Chinese Academy of Sciences (GIG-CAS), in collaboration with international partners, uncovers how deeply subducted carbonates reshape the Earth's mantle chemistry, influencing both diamond formation and the evolution of cratonic lithosphere. Using high-pressure experiments that simulate depths from 250 to 66
