Manganese(II) carbonate
Manganese carbonate decomposes with release of carbon dioxide, i.e. calcining, at 200 °C to give MnO1.88: MnCO3 + 0.44 O2 → MnO1.8 + CO2 This method wikipedia.org

Magnesium carbonate
This process is called calcining: (ΔH = +118 kJ/mol) The decomposition temperature is given as 350 °C (662 °F). steps occur at 157 °C and 179 °C as follows: at 157 °C at 179 °C Uses The primary use of magnesium carbonate is the production of magnesium oxide by calcining wikipedia.org

Magnesium oxide
Mg2+ + Ca(OH)2 → Mg(OH)2 + Ca2+ Calcining at different temperatures produces magnesium oxide of different reactivity. Calcining temperatures 1000 – 1500 °C produce hard-burned magnesia, which has limited reactivity and calcining at lower temperature, (700–1000 °C) produces wikipedia.org
