What is the difference between calcite and aragonite?

Calcite and aragonite are both forms of calcium carbonate, but they have different crystal structures. Calcite has a trigonal crystal structure, while aragonite has an orthorhombic crystal structure. Aragonite is also slightly denser and usually forms in more unstable environments compared to calcite.


How is calcite different from aragonite?
