Uses of Gypsum- Introduction, Formation, Different ...

Gypsum is a type of soft sulfate mineral known for its usefulness in day-to-day lives. It is also referred to as calcium sulfate dihydrate. It consists of water, calcium sulfate and oxygen molecules and is chemically represented by the formula CaSO 4.2H 2 O. An evaporite mineral, gypsum is mostly found in layers of sedimentary rocks on the earth’s crust along with other

G. Cressey, in Encyclopedia of Geology, 2005 Introduction. Gypsum (CaSO 4 2H 2 O), the most common of the sulphate minerals, is also known as alabaster (a fine-grained massive form), satin spar (a fibrous variety of gypsum), or selenite (colourless transparent gypsum crystals). Gypsum is often found in considerable thicknesses within evaporite sequences and in association with

Gypsum: Types, Properties, Advantages Disadvantages

Introduction to Gypsum: The word gypsum is derived from a Greek word meaning ‘to cook’ known as a burnt or calcined mineral. Gypsum is extensively used as a construction material; it contains 70% of CaSO4, 2H20 can be used for building construction. Chemically, gypsum is a sulfate of calcium with two molecules of water i.e. CaSO4, 2H20.

Gypsum - Mineral and Healing Properties

Gypsum is a common mineral, with thick and extensive evaporite beds in association with sedimentary rocks. Deposits are known to occur in strata from as far back as the Archaean eon. Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins.
