The Virtual Cave: Aragonite Frostwork

Aragonite, like calcite, is made up of calcium carbonate (CaCO3). It differs from calcite, however, in its internal crystalline structure. Dense masses of tiny aragonite crystals can be difficult to distinguish from calcite, but when the crystals are large, they reveal a distinctive external form, or crystal habit.

Ironically, the mineral aragonite is dimorphous with the mineral calcite in that they have the same calcium carbonate chemistry, but different structures. The size of calcium is the same in both minerals, but different crystallization temperatures, pressures and other parameters will determine the structure of the crystallizing mineral.
