| Title | Aragonite |
|---|---|
| Description | The photo shows a “rose” of aragonite that is about 6 cm across. Aragonite is a polymorph of calcite, meaning it has the same composition (CaCO3) but different structure and crystal forms. At the Earth surface, aragonite is thermodynamically less stable than the more common calcite, but forms by some disequilibrium processes. This photo is 12 cm across. |
