Calcite is the most abundant carbonate mineral. It typically forms by organic processes or precipitation from oversaturated water. It also occurs in caves, where calcite forms stalactites and stalagmites. Calcite and other carbonate minerals also precipitate from hydrothermal waters (warm waters), especially in ore deposits and …

Sodium carbonate‐bicarbonate minerals as indicators of Pco2. The CO2 content of a gas phase equilibrated with the assemblages nahcolite + trona + solution, nahcolite + trona + halite + solution, and trona + thermonatrite + solution has been determined at 1 atm pressure, using an infrared method. Equilibrium was approached from both sides.

Rather, given that the calculated SI values for both minerals in both bicarbonate leach tests were −1.98 or lower and that anhydrous sodium carbonate polymorphs (e.g. Na2CO3) have higher solubility (Monnin and Schott, 1984), these minerals probably formed as a result of evaporation during sample drying.
