Calcium carbonate forms as both Aragonite and Calcite, and these two minerals only differ in their crystallization.Calcite, the more common mineral, forms in trigonal crystals, whereas Aragonite forms orthorhombic crystals. On occasion, crystals of Aragonite and Calcite are too small to be individually determined, and it is only possible to distinguish these two minerals with optical or …
