• Difference Between Calcite and Aragonite | .

    The key difference between calcite and aragonite is that the crystal system of calcite is trigonal, whereas the crystal system of aragonite is orthorhombic.. Both calcite and aragonite are two different forms of the same compound, i.e., calcium carbonate (CaCO 3).Since they are different structures of the same chemical compound, we call them polymorphs.
