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 is also an ingredient of surgical splints, casting molds and modeling, utilizing the property of coagulation. Furthermore, gypsum is used for soil improvement in the form of fertilizer and soil conditioner. Gypsum is often used as part of a strategy to correct compacted soil or soil
Gypsum is mined from sedimentary rock formations around the world. It takes the form of crystals which can at times be found projecting from rock leading to its old English name of the Spear Stone. The largest gypsum quarries in Europe are found in France, Germany, Italy, Poland, Spain, and the UK.
3 Minerals An Introduction to Geology. Gypsum crystal. Sulfate minerals contain a metal ion, such as calcium, bonded to a sulfate ion. The sulfate ion is a combination of sulfur and oxygen (SO 4 2). The sulfate mineral gypsum (CaSO 4 ᐧ2H 2 O) is used in construction materials such as plaster and drywall.
Introduction Mineral Gypsum. Gypsum plaster, white cementing material made by partial or complete dehydration of the mineral gypsum, commonly with special retarders or hardeners added. Applied in a plastic state with water, it sets and hardens by chemical recombination of the gypsum with water. For especially hard finish.

From Mines to Mars. Gypsum is a common mineral. It is found in layers that were formed under salt water millions of years ago. When water evaporated, it left the mineral behind. Gypsum is mined from sedimentary rock formations around the world.
Gypsum. Gypsum is a mineral found in crystal as well as masses called gypsum rock. It is a very soft mineral and it can form very pretty, and sometimes extremely large colored crystals. Massive gypsum rock forms within layers of sedimentary rock, typically found in thick beds or layers.
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 limestones
Gypsum, common sulfate mineral of great commercial importance, composed of hydrated calcium sulfate. It occurs in extensive beds associated with other evaporite minerals, particularly in Permian and Triassic sedimentary formations; it is deposited from ocean brine, followed by anhydrite and halite.
Gypsum is one of the more common minerals in sedimentary environments. It is a major rock forming mineral that produces massive beds, usually from precipitation out of highly saline waters. Since it forms easily from saline water, gypsum can have many inclusions of other minerals
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
In this edition of Introduction to the Rock-Forming Minerals, most of the commonly occurring minerals of igneous, metamorphic and sedimentary rocks are discussed in terms of structure, chemistry, optical and other physical properties, distinguishing features and paragenesis.
Gypsum, also known as hydrated calcium sulfate, is a mineral that can be commonly found in marine evaporites, and in Permian and Triassic sedimentary formations. It can also be found in saline lakes, shale, limestone, dolomitic limestone, sedimentary rocks, hot springs, and some caves, where the air is dry enough to facilitate the deposition of this mineral.

minerals, such as gypsum, opal, borax, chalcancite, epsomite, and smectite, etc., are common. The water of hydration in these natural crystals plays important roles in co-constituting the structural frameworks with mineral ions. Water of hydration molecules in minerals, in general, do not form the extended hydrogen-bonding network found in bulk
recognize which minerals are "heavy" and which minerals are "light". Property 4: Hardness (talc, gypsum, graphite, quartz, corundum, diamond) Some minerals are hard, some minerals are soft and this is useful as a means of identification. Mineral hardness was first qualitatively employed by an Austrian-German mineralogist named Frederick Mohs.
