Gypsum is considered both a sedimentary rock and a mineral. Its chemical formula is CaSO 4 ∙2H 2 O. Because gypsum formed when ancient seas evaporated in Oklahoma during Permian time (299-251 million years ago), geologists classify it as an evaporite.Western Oklahoma has many large deposits of gypsum totaling trillions of tons (Figure 1).

Gypsum Board Production Of Gypsum Board. First, we produce gypsum board from a mineral rock. It is called gypsum. Then, we extract the gypsum from mining sites. There are two ways of exploitation. On the one hand, we use underground mining. This is done when the raw material is deeply buried. On the other hand, there is an open pit mining.

Here we report the mechanism by which gypsum rocks from the Atacama Desert, Chile, provide water for its colonizing microorganisms. We show that the microorganisms can extract water of crystallization (i.e., structurally ordered) from the rock, inducing a phase transformation from gypsum (CaSO 4 ·2H 2 O) to anhydrite (CaSO 4).

More than 5 million tons of gypsum is mined in Oklahoma annually involving 22 companies strung out across seven western counties. Major County is the leading state source of gypsum, producing more that 1.7 million tons a year. Figures from the U.S. Geological Survey show Oklahoma leading the nation in gypsum mining and in gypsum food additives.

The large crack in the middle of the red rock wall is on an earthquake fault. The light-colored peak to the left is gypsum. The picture at left was taken from the west side of the quarry where USGC is constructing a road to the top of the ridge to get at more gypsum. Gypsum is mined from the top of the hill to the bottom.

Deep below the rugged surface of Indiana''s Martin County people work in two underground mines to extract and process an unusual mineral resource
Development and Mining. Overburden at the Bestwall operations is composed of 2 to 3 feet of soils underlain by 50 to 60 feet of glacial drift and gumbotil. The gypsum ranges from 20 to 27 feet in thickness and averages about 23 feet. The original stripping operations exposed the gypsum for a length of about 1,500 feet and a width of 75 feet.

The dirty diamonds do have good cleavage in one direction, which can produce thin sheets of gypsum. Gypsum crystals often fluoresce light yellow in short-wave ultraviolet light, and occasionally they are phosphorescent. Gypsum has the same chemical composition as the mineral anhydrite, but contains water in its structure, whereas anhydrite does

Gypsum rock is usually white or colourless, although it may sometimes have grey, yellow, pink, or brown hues. Gypsum is much softer than minerals of similar colour, such as calcite or quartz, and is the only one that can be scratched with a fingernail. If a piece of gypsum rock is held over a flame it will turn cloudy and opaque and give off water.
