Anhydrite - Wikipedia
WEBAnhydrite, 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 …

WEBAnhydrite also occurs as a vein-filling mineral in hydrothermal deposits. It is deposited from solution, often along with calcite and halite, as gangue in sulfide mineral deposits. Anhydrite is also found in the cap rock of salt domes.. Anhydrite is an anhydrous calcium sulfate with a composition of CaSO 4.It is closely related to gypsum, which has a …
Anhydrite | Properties, Formation, Occurrence and Uses Area
WEBApr 21, 2024 · Anhydrite is a mineral that belongs to the sulfate mineral group. Its name is derived from the Greek words "an" (without) and "hydros" (water), indicating its lack of water content. Anhydrite is composed of calcium sulfate (CaSO4) and is chemically very similar to another well-known sulfate mineral, gypsum (CaSO4·2H2O).

WEBAnhydrite is an important constituent of white, usually marginal, zones of amygdules residing within the slag sample LdS15 (Figure 13.2.7C and D).However, it is also found in the blue, apatite-group-bearing internal zones. An analytical report for anhydrite is given in Table 13.2.3.A unique feature of this anhydrite is the molybdenum admixture, which …
Anhydrite – WGNHS – UW–Madison
WEBAnhydrite is a relatively common mineral usually formed as a chemical precipitate from saline water in limestone, dolostone, and salt beds. Its presence is obscured by its tendency to dissolve or be altered to gypsum when exposed to groundwater or surface weathering. Its true extent is most often documented in areas that have been drilled extensively during …
