Himalayan Salt (Halite)

Physical Properties

Hardness: 2-2.5 on Mohs scale; Color: Pink, orange, or reddish due to iron oxide impurities; Luster: Vitreous; Crystal Structure: Cubic/Isometric; Cleavage: Perfect cubic; Specific Gravity: 2.1-2.6

Formation & Geological History

Formed by the evaporation of ancient sea beds during the Precambrian and Paleozoic eras. These large salt deposits were buried by tectonic shifts and compressed under the Himalayan mountain range over 200 million years ago.

Uses & Applications

Commonly used for salt lamps, culinary seasoning, spa treatments, and decorative objects. It is also used in the chemical industry for producing chlorine and sodium hydroxide.

Geological Facts

Despite the name, most Himalayan salt is mined from the Khewra Salt Mine in Pakistan. It is considered one of the purest forms of salt on Earth because it was protected by lava and snow for millions of years.

Field Identification & Locations

Identify by its characteristic cubic cleavage, salty taste (not recommended for field identification due to hygiene), and susceptibility to dissolving in water. It is notably hygroscopic, meaning it attracts water molecules from the air.
