Pink halite (rock salt)

Halite (NaCl), likely iron- or clay-tinged pink halite

AI-generated identification · may be incorrect

Typically colorless to pink/orange, with a vitreous to slightly dull luster and cubic cleavage; Mohs hardness 2–2.5 and specific gravity about 2.16. The specimen appears translucent, granular, and irregularly cleaved, though the image is somewhat out of focus.

Physical properties

Formation & geological history

Forms by evaporation of saline lakes, restricted seas, and underground brines; pink coloration commonly comes from microscopic inclusions or impurities. Deposits range from modern evaporites to very ancient sedimentary salt beds, including Permian formations.

Uses & applications

Used industrially for chlorine and sodium hydroxide production, water softening, deicing, food seasoning, and salt lamps; attractive pink specimens are collected or sold decoratively.

Geological facts

Halite is rock salt’s principal mineral and has a distinctly salty taste, but tasting specimens is not recommended. Its perfect cubic cleavage is a key diagnostic feature.

Field identification & locations

Common localities include Pakistan’s Khewra Salt Mine, Poland, Utah, and other evaporite basins. Confirm with cubic cleavage, low hardness, and strong solubility in water; avoid confusing it with pink calcite or quartz.
