Anhydrite: The mineral anhydrite information and pictures

Anhydrite is not a common mineral, as it easily alters to the much more common mineral Gypsum from the addition of water into its chemical structure.Anhydrite and Gypsum are chemically similar, except Gypsum has the addition of water. In fact, the name of Anhydrite is derived from "An" and "Hydra" - meaning "without water" - in reference to its similarity to Gypsum but the fact that it lacks ...

Anhydrite - Wikipedia

Anhydrite, or anhydrous calcium sulfate, is a mineral with the chemical formula CaSO 4.It is in the orthorhombic crystal system, with three directions of perfect cleavage parallel to the three planes of symmetry.It is not isomorphous with the orthorhombic barium and strontium sulfates, as might be expected from the chemical formulas.Distinctly developed crystals are somewhat rare, the mineral ...

Anhydrite | mineral | Britannica

Anhydrite, an important rock-forming mineral, anhydrous calcium sulfate (CaSO 4).It differs chemically from gypsum (to which it alters in humid conditions) by having no water of crystallization. Anhydrite occurs most often with salt deposits in association with gypsum, as in the cap rock of the Texas-Louisiana salt domes. Anhydrite is one of the major minerals in evaporite deposits; it also is ...

Get to Know the 7 Delicate Sulfate Minerals

Jun 14, 2019 · Anhydrite is calcium sulfate, CaSO 4, similar to gypsum but without its water of hydration. The name means "waterless stone," and it forms where low heat drives the water out from gypsum. Generally, you won't see anhydrite except in underground mines because, at the Earth's surface, it swiftly combines with water and becomes gypsum.

Gypsum Mineral | Uses and Properties

Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.
