| Title | Aragonite |
|---|---|
| Description | This photo shows a cluster of tabular (thin elongate prisms) aragonite crystals about 8 cm across. Other common habits for aragonite include crystals that appear as twinned hexagonal prisms, curved bladed crystals, and steep pyramidal (spiked) and chisel shaped crystals. Aragonite is a polymorph of calcite, meaning it has the same composition but different structure and crystal shape. At the Earth surface, aragonite is thermodynamically less stable than the more common calcite, but forms by some disequilibrium processes. |
