Physical properties
Mohs hardness of 3, yellow to orange color, vitreous to earthy luster, trigonal crystal system, and perfect rhombohedral cleavage.
Formation & geological history
Formed through the precipitation of calcium carbonate from hydrothermal solutions or marine environments over millions of years.
Uses & applications
Used in optical devices, construction materials, agricultural soil treatment, and as a popular mineral specimen for collectors.
Geological facts
Calcite exhibits strong double refraction, splitting light into two separate rays when viewed through transparent crystals.
Field identification & locations
Easily identified by its rapid effervescence when exposed to dilute hydrochloric acid and its soft three-directional cleavage.
