Deep carbon cycle constrained by carbonate solubility
Nature Communications, 2021 Carbonate mineral aqueous solubility decreases as carbonates become more Mg-rich during subduction. Coupled with regional variations in amounts of carbon and water subducted, this explains discrepancies in estimates of carbon recycling, suggesting that ...
