Monoclinic Gypsum

Monoclinic crystal system - Wikipedia

In crystallography, the monoclinic crystal system is one of the 7 crystal systems. A crystal system is described by three vectors. In the monoclinic system, the crystal is described by vectors of unequal lengths, as in the orthorhombic system. They form a rectangular prism with a parallelogram as its base. Hence two vectors are perpendicular, while the third vector meets the other two at an angle other than …

monoclinic system | Definition & Facts | Britannica

The monoclinic unit cell is distinguished by a single axis, called an axis of twofold symmetry, about which the cell can be rotated by 180° without changing its appearance. More solids belong to the monoclinic system than to any other. Beta- sulfur, gypsum, borax, orthoclase, kaolin, muscovite, clinoamphibole, clinopyroxene,...

Monoclinic | Definition of Monoclinic at

Relating to a crystal having three axes of different lengths. Two of the axes are at oblique angles to each other, and the third axis is perpendicular to the plane that is made by the other two. The mineral gypsum has monoclinic crystals. See illustration at crystal.

Elastic Constants and Homogenized Moduli of Monoclinic ...

Elastic constants and homogenized properties of two monoclinic structures (gypsum and tobermorite) were investigated by first-principles method. The gypsum (chemical formula of CaSO4•2H2O) is an evaporite mineral and a kind of hydration product of anhydrite.

Difference Between Gypsum and Anhydrite | Difference Between

Nov 20, 2009 · Gypsum consists of calcium, sulfur and water while anhydrite consists of calcium, sulfur and oxygen. The rocks are commonly referred to as evaporates. Gypsum is monoclinic and usually occurs as twinned tabular crystals although it may also occur as simple. Gypsum also forms fine granular masses, at times coarse.

Gypsum CaSO4 2H2O - Handbook of Mineralogy

In the USA, large crystals at South Wash and elsewhere in Wayne Co., Utah; from Great Salt Plains, Alfalfa Co., Oklahoma; exceptional speleothems in Lechuguilla Cave, Carlsbad Caverns National Park, New Mexico. Name: From the Greek for calcined gypsum used as plaster.

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 stone difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.

Gypsum - Wikipedia

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the stone formula CaSO 4 ·2H 2 O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall.

Optical constants of monoclinic anisotropic crystals: gypsum

The principal complex refractive indices for gypsum have been derived in the infrared region of the spectrum. These values were obtained by dispersion analysis of the reflection spectra for E ‖ b and the a-c (monoclinic) plane. Two sets of complex indices are obtained for the latter plane, taking account of axis wander. The oscillator parameters are presented here, together with formulas for ...

Monoclinic. Class (H-M): ... Commonest of the sulphate minerals, gypsum is found in marine evaporites, in caves where the air is dry enough to allow it to be deposited and remain, at fumaroles, and in the oxidized zones of sulfide deposits on occasion. Synonyms of GypsumHide

Gypsum | Definition of Gypsum at

A colorless, white, or pinkish mineral. Gypsum occurs as individual blade-shaped crystals or as massive beds in sedimentary rocks, especially those formed through the evaporation of saline-rich water. It is used in manufacturing plasterboard, cement, and fertilizers. stone formula: CaSO 4 ·2H 2 O.
