Mineralization Of Gypsum

DEFORMATION, METAMORPHISM, AND MINERALIZATION IN

Gypsum first forms as sharply defined crystals mostly smaller than the anhydrite crystals they replace, but not necessarily falling within the limits of a single anhydrite crystal. Integration into larger crystals takes place very irregularly and complexly, but the end product is large, clear, homogeneous crystals. To explain the complexity in integration it is suggested that the water of ...

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

Gypsum - an overview ScienceDirect Topics

Gypsum is much softer than minerals of similar color, such as calcite or quartz, and is the only one that can be scratched with a fingernail. If a piece of gypsum is held over a flame, it will turn cloudy and opaque and give off water. Some gypsum sand deposits contain only about 60 percent gypsum, and these are not very suitable for producing a plaster. Those containing

University of Minnesota’s Mineral Pages: Gypsum

Gypsum is a very soft mineral that is easily identified by its hardness, cleavage, and solubility in water. Typically clear to white, gypsum may be colored reddish to brown or yellow if impurities are present. Most gypsum occurs in its massive form, as layers of rock that often intercalate layers of shale, limestone, or dolostone. Alabaster is a common name used for particularly
