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.”
