Abstract
It is possible to observe the known transformations of aragonite to calcite to lime using an electron microscope. Aragonite undergoes a sudden and violent transformation when heated by the electron beam. Twins and dislocations disappear, leaving a strained crystal of aragonite of occasionally calcite. Further heating produces calcium oxide with a strongly preferred orientation relative to the carbonate.Keywords
