Figure 5From: On the potential for CO2mineral storage in continental flood basalts – PHREEQC batch- and 1D diffusion–reaction simulationsPorosity changes caused by the basalt alteration at 40 to 100 C. Secondary hydrated species and carbonates incorporate the H2O and CO2 masses into the solids and clogs the pore space. As reaction rates increase exponentially with temperature, the pore space is filled up faster at the higher temperatures.Back to article page
