Physical properties

Hardness: 2-2.5 on Mohs scale; Color: typically colorless or white; Luster: vitreous (glassy); Crystal structure: cubic; Cleavage: perfect cubic; Specific gravity: 2.16

Formation & geological history

Formed through the evaporation of saline water in sedimentary basins or dry lake beds (evaporites) over millions of years.

Uses & applications

Source of common table salt, used for road de-icing, chemical industry (chlorine and caustic soda production), and food preservation.

Geological facts

Halite is the mineral form of sodium chloride. It has a characteristic salty taste, though tasting unknown minerals in the field is generally discouraged.

Field identification & locations

Identify by its cubic shape, softness (can be scratched by a copper penny), and solubility in water. Commonly found in salt flats or underground salt mines globally.
