From: Unraveling the rapid CO2 mineralization experiment using the Paraná flood basalts of South America
pH values of the carbonic acid solution that percolated into the basalt grains during the CO2 injection experiment. An open system represents a constant flow of 1 L/h during 1 h, whereas a closed system represents a stationary mode for 23 h (without constant flow/outflow in the experiment).
