Physical properties

Formation & geological history

Calcite forms in sedimentary deposits, hydrothermal veins, and cavities in rocks; it occurs from many geological ages. Pink or peach coloration commonly results from trace impurities.

Uses & applications

Used in cement and lime production, construction aggregate, and as a decorative or collectible mineral; attractive crystals may be used in ornaments.

Geological facts

Calcite effervesces in dilute acid and is strongly birefringent in clear pieces.

Field identification & locations

Look for its softness and rhombohedral cleavage; a small scratch or acid test can help distinguish it from quartz. Common worldwide in limestone and marble regions.
