Polyhalite
Polyhalite is a hydrated sulfate mineral with the chemical formula potassium calcium magnesium tetrasulfate dihydrate. It belongs to the triclinic crystal system and is classified under the sulfate mineral group. The mineral typically exhibits a white streak and a vitreous to pearly luster. Its color is usually white or colorless. With a hardness of approximately 2.5 to 3 on the Mohs scale and a relatively high density, polyhalite is commonly found in evaporite deposits. It is a tectosilicate mineral and is notable for its complex chemical composition, which includes potassium, calcium, magnesium, and sulfur in a hydrated structure.

Etymology
The name 'polyhalite' is derived from the Greek word 'poly,' meaning 'much,' and 'halos,' meaning 'salt,' referring to its high salt content.
Geological genesis
Polyhalite typically forms in evaporite environments, where saline water evaporates and leaves behind mineral deposits. It is commonly associated with other evaporite minerals and is found in sedimentary settings.
Occurrence
Polyhalite is found in evaporite deposits, particularly in sedimentary basins where saline water has evaporated over time. Specific localities are not provided in the given facts.
