Calcite vs Aragonite ThoughtCo

Calcium carbonate chemistry is more complicated when it comes to understanding which polymorph will crystallize out of solution. This process is common in nature, because neither mineral is highly soluble, and the presence of dissolved carbon dioxide (CO 2 ) in water pushes them toward precipitating.
