Gypsum Mineral | Uses and Properties

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical 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.A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including ...

Aug 10, 2019· One way is to determine the mineral's density by putting crushed grains in immersion oils of different densities. (Albite's specific gravity is 2.62, anorthite's is 2.74, and the others fall in between.) The really precise way is to use thin sections to determine the optical properties along the different crystallographic axes.

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 ...

Gypsum - Simple English Wikipedia, the free encyclopedia

Gypsum is a common mineral which is widely distributed in sedimentary rocks, often as thick beds. It frequently occurs interstratified with limestones and shales. Usually to be found as a layer underlying beds of rock salt and has been deposited there as one of the first minerals to crystallize because of the concentration of salt waters.

Gypsum, selenite: The mineral gypsum information and pictures

Gypsum occurs in extensive beds associated with other evaporite minerals (e.g., anhydrite and halite), particularly in Permian and Triassic sedimentary formations; it is deposited from ocean brine, followed by anhydrite and halite.It also occurs in considerable quantity in saline lakes and salt pans and is an important constituent of cap rock, an anhydrite-gypsum rock forming a covering on ...

Gypsum mining, he said, is an expressly regional industry, i.e., roughly 50 % of its overall employment impact is confined to the region. That makes a good argument in discussions about gypsum mining. 'Do good and talk about it! The gypsum industry and its socio-political responsibility' is what Michael Rutz, Berlin, had to say.

What is Gypsum? 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 waters and anhydrite is without water.

Calcium sulfate can exist in many forms, varying by how much water is bound into the minerals' crystalline structure. The multi-filter data from the camera suggest gypsum, a hydrated calcium sulfate. On Earth, gypsum is used for making drywall and plaster of Paris. Observations from orbit have detected gypsum on Mars previously.
