Physical properties
Hardness of 3 on the Mohs scale, orange to yellow-orange color, vitreous to pearly luster, trigonal crystal system, and perfect rhombohedral cleavage.
Formation & geological history
Forms primarily through the precipitation of calcium carbonate from hydrothermal solutions or evaporating marine environments.
Uses & applications
Used in optical equipment, cement manufacturing, soil conditioning, and as a popular specimen in mineral collections.
Geological facts
Calcite exhibits strong double refraction, splitting light rays into two separate paths when viewed through clear crystals.
Field identification & locations
Identified easily by its rapid effervescence when exposed to dilute hydrochloric acid and its distinct rhombohedral cleavage.
