Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. [4] It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, drywall and blackboard or sidewalk chalk. [5][6][7][8] Gypsum also crystallizes as translucent crystals of selenite.

2023年9月9日 · Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate (CaSO4·2H2O). It is commonly found in sedimentary rock formations and is often associated with other minerals such as anhydrite, halite, and sulfur. The name “gypsum” is derived from the Greek word “gypsos,” which means “plaster” or “chalk.”

What is Gypsum? Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite.

2024年12月23日 · 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.

Detailed description, properties, and locality information guide about the mineral gypsum (selenite).

2024年2月24日 · Gypsum is a hydrated calcium sulfate mineral with the chemical formula CaSO4·2H2O. The mineral is made of calcium (Ca), sulfur (S), oxygen (O), and water (H2O).

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.

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.
