Physical properties
Hardness of 3 on Mohs scale, white to grey color with dark dendritic inclusions, vitreous to earthy luster, trigonal crystal system.
Formation & geological history
Formed by hydrothermal fluid precipitation or groundwater filling fractures in pre-existing limestone rock formations.
Uses & applications
Used in educational geology collections, aggregate production, and industrial lime manufacturing.
Geological facts
Calcite exhibits strong effervescence when exposed to dilute hydrochloric acid, producing carbon dioxide bubbles.
Field identification & locations
Identify by its softness, white crystalline fracture infills, and positive acid fizz test; common in limestone-rich regions worldwide.
