On the potential for CO2mineral storage in continental flood basalts – PHREEQC batch- and 1D diffusion–reaction simulations

Table 2 Mineralogy included in the model

The mineralogy of the CRB has been described in [25, 32] and the weight fraction of pyroxene, feldspar and glass was estimated as average values from the reported data.
¹Solid solutions. En (enstatite), Fs (ferrosilite), Wo (wollastonite), An (anorthite), Ank (ankerite), Do (dolomite). For details on the calculations of the ankerite solid solution see [31].
²Superscript ⁰ denotes Standard state (T = 298K, P = 1 atm). The equilibrium constant log K value is that for the forward dissolution reaction for one mole unit of the mineral.
³All thermodynamic data (log K and coefficients for the PHREEQC analytical temperature expression) from the llnl.dat PHREEQC database, except for the solid-solutions first estimated in PHREEQC by ideal solid solutions and then added to the PHREEQC database as new solid solution phases.
