Physical properties
Hardness of 3 on the Mohs scale, yellow to orange color, vitreous to earthy luster, trigonal crystal system, and exhibits perfect rhombohedral cleavage with a specific gravity of 2.71.
Formation & geological history
Formed through the precipitation of calcium carbonate from aqueous solutions, hydrothermal veins, or as a primary component of sedimentary limestone environments.
Uses & applications
Used in construction materials, cement manufacturing, optical items, and as popular decorative mineral specimens for collectors.
Geological facts
Yellow calcite is known for its strong reactions to dilute hydrochloric acid and often displays distinct white rhombohedral cleavage planes.
Field identification & locations
Readily identified by its characteristic softness and effervescence in acid; commonly sourced from Mexico, Brazil, and the USA.
