The mineral aragonite is a calcium carbonate with chemical formula CaCO3. It is an unstable polymorph of calcite and is therefore difficult to distinguish from calcite because most of its properties are the same. A distinction can be made by means of a color test: with a Feigl solution, aragonite becomes black, while calcite remains colorless. Moreover, aragonite is slightly harder than calcite and can be determined by means of a scratch test which mineral is involved. A third distinguishing method is the habit: aragonite usually grows in needle-shaped crystals (acicular), while calcite has a leaf-shaped habit. With the help of powder diffraction the difference can be clearly determined because aragonite has an orthorhombic structure and not a trigonal one like calcite. Aragonite is always formed at low temperatures close to the earth's surface. Aragonite is found in geysers, hot springs, caves, as oolites in shallow seas, in shells and in pearls. Locations in Europe are Aragón (Spain), Limousis (France), Girgenti (Sicily), Bilin (Bohemia) and Eisenertz (Austria).
