Fracture is a break in a mineral that is not along a cleavage plane. Fracture is not always the same in the same mineral because fracture is not determined by the structure of the mineral. Minerals may have characteristic fractures (Figure below). Metals usually fracture into jagged edges. If a mineral splinters like wood, it may be fibrous.
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. Gypsum is often formed from evaporating water and usually contains water ...

Natural gypsum, shown in Fig. 25.1, is the most common raw material for production of binders.It is a soft mineral, attributed to sedimentary rocks, normally grey or with no colour, with a humidity of about 8–10%. Gypseous stone, a denser modification of gypsum that is composed of gypsum and sandy and clayey stone, is normally used to produce gypsum binders.
What is Gypsum? DATE: 16-07-2007 I. Natural Gypsum A. Introduction The mineral Gypsum precipitated some 100 to 200 million years ago when sea water evaporated. From a chemical point of view it is Calcium Sulphate Dihydrate ( CaSO 4.2H 2O) deposited in sedimentary layers on the sea bed. Under high pressure and temperature Gypsum turns into
Gypsum has been used as a building material since the construction of the ancient Egyptian pyramids. Over the past 3,500 years, or so, it has become one of the most important minerals used in manufacturing construction materials and many other products.
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 …
3 Mineral Properties. KEY CONCEPTS. Mineral names derive from mineral appearance, composition, provenance, and many other things. ... appearing as a solid mass with no distinguishing features: granular: composed of many individual grains: ... Other minerals, such as gypsum, are sectile, which means they can be cut into thin pieces with a knife.
Gypsum is a very soft mineral composed of calcium sulfate dihydrate and often occurs in nature as flattened and often twinned crystals and transparent cleavable masses called selenite.
Gypsum The most common of the sulfate minerals, this mineral is found in marine evaporites, in caves, fumaroles, and in the oxidized zones of sulfide deposits. When formed as clear crystals, it is referred to as selenite. The fibrous variety is known as satin spar and also forms in "roses." It is used chiefly for the production of plaster ...
Features of drywall gypsum board. Drywall gypsum boards have several features that make it unique and distinguish it from its counterparts. Let's have a look at these features and to understand its function better: Composition. These boards are mainly composed of gypsum, a sulphate-based mineral, that is sandwiched between two layers of paper.
Gypsum, a naturally occurring mineral with the chemical formula CaSO4·2H2O, exhibits several important chemical properties that contribute to its versatility and usefulness in various applications. Here are some key chemical properties of gypsum: 1. Hydrated Structure:Gypsum is a hydrated …
Gypsum has the following properties: Mohs Scale Hardness: 1.5 – 2 Specific Gravity: 2.31 – 2.33 Gypsum Streak: White Fracture: Conchoidal, splintery (parallel) Gypsum Luster: vitreous, silky, pearly, waxy Crystal System: Elongated prismatic crystals.Flat Gypsum Chemical Formula: CaSO 4 ·2H 2 O
Gypsum forms stalactites and other intriguing cave features, while a huge expanse of gleaming white dunes of pure gypsum sand is the main attraction at New Mexico's White Sands National Park. Few other minerals …
Gypsum (CaSO4·2H2O) is the most common sulfate mineral on Earth and is also found on Mars. It is an evaporitic mineral that predominantly precipitates from brines. In addition to its precipitation in natural environments, gypsum also forms an undesired scale in many industrial processes that utilize or produce brines. Thus, better insights into gypsum formation …
Gypsum is a very common, soft sulfate mineral composed primarily of calcium sulfate dihydrate, with the chemical formula CaSO₄·2H₂O. Visually, it can be colorless or white, but impurities can also give it a variety of hues.

Cleavage planes in gypsum crystals are a defining feature of the mineral's structure. Gypsum exhibits perfect cleavage along its planes, allowing it to easily split into thin sheets or plates. This unique characteristic is a result of the crystal's internal atomic arrangement, which enables it to break cleanly and smoothly along these planes.
Geology and Properties of the Calcium Sulfate Minerals Properties of Gypsum Physical properties. Gypsum (CaSO 4 · 2H 2 O) has a specific gravity of 2.32 and hardness of 2. It is commonly colorless, white, or gray. Shades of yellow, red, and brown result from impurities. Crystals, when present, are generally of tabular or prismatic habit and ...
Some people even include gypsum into their fertilizers. This mineral is popular with collectors, but it is not often used in jewelry due to its softness. Physical Properties and Structure. The chemical formula for gypsum is CaSO 4.2H 2 O (calcium sulfate dihydrate). Gypsum forms typical monoclinic crystals.
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.

Gypsum is by far the dominant sulfate mineral in soils. A saturated gypsum solution at 25C contains ~15 mM CaSO 4, or 2.63 g/L. It is approximately 100 times less soluble than other common sulfate minerals. Gypsum is not common in soils of more humid regions due to its relatively high solubility in water and its rapid removal in leachate.
