Physical properties
Hardness of 3 on the Mohs scale, yellow to golden color, vitreous to earthy luster, rhombohedral crystal structure, and perfect cleavage in three directions.
Formation & geological history
Forms primarily in sedimentary environments through the precipitation of calcium carbonate from marine waters, as well as in hydrothermal veins and hot spring deposits.
Uses & applications
Widely used in construction materials, optical components, neutralizing acidic soils, and as a popular mineral specimen for collectors.
Geological facts
Calcite exhibits strong double refraction, meaning light splits into two separate rays when passing through a clear specimen.
Field identification & locations
Easily identified by its characteristic rhombohedral cleavage and strong effervescence when exposed to dilute hydrochloric acid; found globally.
