Why doesn''t limestone thermally decompose instead of

Pure limestone and marble are composed of calcium carbonate: CaCO 3. In air, the temperature required for calcium carbonate decomposition is 898 °C (considering simple equilibrium and ignoring any vapour pressure effects). As pressure increases, the temperature requirement for this equilibrium decomposition increases very rapidly.
