Voigt, Martin; Marieni, Chiara; Baldermann, Andre; Galeczka, Iwona M.; Wolff-Boenisch, Domenik; Oelkers, Eric H.; Gislason, Sigurdur R. (2021): An experimental study of basalt–seawater–CO2 interaction at 130 °C. In Geochimica et Cosmochimica Acta 308, pp. 21–41. DOI: 10.1016/j.gca.2021.05.056.

„Over millions of years, the interaction of marine basalt with percolating seawater in low-temperature ocean floor hydrothermal systems leads to the formation of calcite and aragonite. The presence of these minerals in marine basalts provides evidence for substantial CO₂ fixation in these rocks. Here, we report on laboratory experiments to study this process under enhanced CO₂ partial pressures (pCO₂) at 130 °C. Mid-ocean-ridge-basalt (MORB) glass was reacted with North Atlantic Seawater charged with CO₂ in batch experiments lasting up to 7 months.“
