Hadal aragonite records venting of stagnant paleoseawater in the hydrated forearc mantle
Veins of aragonite in deep ocean trenches can record discharges of CO2-rich paleoseawater and suggest that exposed serpentinized forearcs can act as carbon reservoirs, according to residence time calculations based on geochemical analyses of mantle rocks from offshore Japan.
