Anhydrite: The mineral anhydrite information and pictures

Some of the best Anhydrite on the mineral market is the light blue dense fibrous veins, some quite large in size, from the mines at Naica, Chihuahua, Mexico. In Canada, Anhydrite comes from Faraday in the Bancroft District, Hastings Co., Ontario.

Anhydrite - an overview ScienceDirect Topics

Anhydrite, CaSO 4, is a common mineral at the Anna I dump in different associations. It usually forms visually attractive specimens with white opaque elongated crystals ( Blaß and Strehler, 1993 ). In rare cases (in the hottest vents at c. 200 °C), nice translucent crystals can be observed.

Gypsum is a very common mineral; only a select few of the best and most classic are mentioned here. The finest European localities are Lubin, Poland; Kapnick, Maramures Co., Romania; and the Sulfur mines of Agrigento Province, Sicily, Italy. Desert Roses and Sand Gypsum come from several places in the Sahara Desert in Algeria and Morocco. Excellent Gypsum specimens have come from China at ...

Anhydrite - an overview ScienceDirect Topics

Indirect information on rainfall during the Paleozoic comes from (1) geographical distribution and kinds of evaporite deposits, such as hematite, gypsum, anhydrite, phosphorites and bauxite, and (2) location and extent of coal beds. Since the first fossil seeds are from the Devonian (see “Fossil Seeds”, p. 1038), we will begin with this Period.

Anhydrite Mineral Uses and Properties

Anhydrite 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

Origin and diagenesis of gypsum and anhydrite Journal of ...

A diagenetic cycle exists in the calcium sulfate minerals. Gypsum is deposited by precipitation or by growth of crystals in unconsolidated rocks near the surface. This primary gypsum is replaced, with burial, by anhydrite at a temperature of 42 degrees C and theoretical depth of 2,000 feet. Anhydrite (metagypsum) occurs as beds and pore-fillings.

Minerals Filling in Anhydrite Dissolution Pores and Their ...

Mold pore cementation is the key factor constraining the reservoir property in the study area. The anhydrite dissolution pores in the Ordovician Majiagou Formation of southeastern Ordos Basin are commonly filled by minerals such as dolomite, calcite, pyrite, and quartz accounting for more than 90% of the total molds resulting in significant porosity volume reduction.

Anhydrite --MIROFOSS--

Anhydrite is not isomorphous with the orthorhombic barium (barite) and strontium (celestine) sulfates, as might be expected from the chemical formulas. Distinctly developed crystals are somewhat rare, the mineral usually presenting the form of cleavage masses. Other than in the basic mineral form, anhydrite

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

THE STABILITY OF GYPSUM AND ANHYDRITE

2019-4-12  soluble anhydrite (CaSO). At about 3700C this is converted to the insoluble anhydrite (CaSOj), a polymorph of the soluble anhydrite. Continued heating above this temperature will produce no change until 11930C is reached where a high temperature form of anhydrite appears. At 12500 C dis-sociation occurs and the CaSO4 is partially broken down to

The Carbonatation of Anhydrite: Kinetics and Reaction ...

2017-2-10  A textural and kinetic investigation of the carbonatation of anhydrite in the presence of carbonate- and bicarbonate-bearing solutions under static conditions was conducted. The replacement occurs via a coupled dissolution–precipitation mechanism. Textural and kinetic evidence indicates that the rate-limiting step in the replacement reaction was the dissolution of anhydrite and that the ...
