University of Minnesota's Mineral Pages: Calcite

Aragonite is a polymorph of calcite, a mineral that has the same chemical composition as calcite, but has a slightly different crystal structure. For most purposes aragonite and calcite can be considered to be the same mineral. In its crystal form, aragonite tends to have needlelike crystals and lacks calcite's rhombohedral cleavage.
