Thermal etch pits are observed on calcite cleavages when the latter are kept at 520°C to 560°C in atmosphere for some hours. Boundaries of the above etch pits are circular, hexagonal and rhombic and they are dependent upon the temperature of etching. Different etch pit morphology is observed in chemical etching on calcite cleavages. It is conjectured that origin of thermal etch pits are different from that of chemical etch pits.
