Physical properties
Mohs hardness of 3, white or colorless, vitreous to earthy luster, rhombohedral crystal system with perfect cleavage in three directions, specific gravity of 2.71.
Formation & geological history
Formed through precipitation from aqueous solutions, hydrothermal veins, or organic accumulation in sedimentary environments.
Uses & applications
Used widely in construction materials, cement manufacturing, agriculture for soil conditioning, and optical equipment.
Geological facts
Calcite exhibits strong optical birefringence, splitting light into two separate rays. It is the primary mineral constituent of limestone and marble.
Field identification & locations
Easily identified by its characteristic rhombohedral cleavage and strong effervescence when exposed to dilute hydrochloric acid.
