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. Gypsum is the most common sulfate mineral.

Gypsum is a mineral found in sedimentary environments throughout the world. It is commonly found in large deposits resulting from precipitation from saline waters. Its formation it may have other mineral deposits including air bubbles created during its formation. Common names of gypsum include Selenite, Satin spar, and Alabaster.

Mining Gypsum (rock) Gypsum is a soft, light-colored sedimentary rock deposited in ancient seas that covered Ohio during the Silurian Period. It occurs in both mineral form (selenite) and as a rock in bedded layers. Gypsum occurs interbedded with salt (halite, NaCl) and anhydrite (CaSO 4 ).

Gypsum (CaSO4 · 2H2O), 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 and shales.

Gypsum outcrop in Clark County. Gypsum is an evaporite because it precipitates (settles) out of water as the water evaporates. the three varieties of gypsum are selenite, satin spar, and rock gypsum. Selenite, found throughout the Red Hills, has flat, diamond-shaped crystals that can be split into thin sheets.Satin spar is white or pink and fibrous with a silky luster.

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.
