Physical properties
Mohs hardness of 2.5, white to colorless, vitreous luster, isometric crystal system with perfect cubic cleavage, specific gravity of 2.16.
Formation & geological history
Formed through the evaporation of ancient marine or inland salt water bodies (evaporite deposits), often occurring in arid sedimentary basins.
Uses & applications
Extensively used in food seasoning, chemical manufacturing, de-icing roads, and carved into decorative salt lamps.
Geological facts
Halite dissolves easily in water and can form unique cave systems and diapirs (salt domes) that rise through overlying rock layers due to buoyancy.
Field identification & locations
Easily identified by its distinctive salty taste, cubic cleavage, and low hardness. Found worldwide in sedimentary salt beds, notably in Poland, Germany, and the USA.
