(1) transition metal carbonates (for example, siderite, FeCO3, and rhodochrosite, MnCO3) decompose, yielding carbon dioxide, CO2, in the range of 220 C to 520 C; (2) calcite decomposes slightly between 300 C and 500 C, although most decomposition occurs above 550 C; (3) dolomite decomposes at 800 C to 900 C (Hammack, 1994, p. 440). )
These test methods also may be used for the classification of rock to be used in construction, where the potential to generate acid under environmental conditions
