Calcite dissolution kinetics in view of Gibbs free energy, dislocation density, and pCO2

► Calcite dissolution kinetics in a full range of saturation states (Ω). ► Effects of ΔG, dislocation density, and atmospheric pCO2 on the dissolution kinetics. ► TST model is not sufficient to depict the R − ΔG relations when Ω falls from its extrema. ► Step retreat along the cleavage directions overwhelms the effect of etch pits.
