    • In a calibration run on the TEGA engineering qualification model with a known amount of calcite, we found the heat of transition to be 2550 J/g, which implies 2.4 mg of CaCO° in the Wicked Witch sample

    • Estimation of the concentration of calcium carbonate in the sample is uncertain because the mass of sample in the oven is not tightly constrained. We estimate that this error is on the order of ± 25

    • A previous experiment suggested that carbonate could form in relatively dry Mars-like conditions as submi-crometer coatings on soil particles (5, However, the results from this study cannot be extrapolated over time because the experiments did not proceed beyond a monolayer of carbonate. A more comprehensive experimental study under Mars-like conditions showed that, in a given time span, carbonate forms on the surface of basaltic particles in an amount that increases with the thickness of films of water around the particles (30, 31, Growth of more than a monolayer of carbonate occurs with logarithmic reaction kinetics. For damp or wet conditions (meaning 0.1 to 0.5 g H2O per g soil, equivalent to 102 to 103 monolayers of water, the number of CO2-reacted monolayers of substrate, L, per particle is found empirically to follow the relationship (30, 32) L(t, Dlog101, t/t0, Eq. 1, Here, the constant of proporti
