Gypsum properties. Chemical Composition. (CaSO4-2H2O) – Hydrated Calcium Sulfate. Color. Usually white, colorless or gray in massive form, crystals are clear, transparent to translucent. If impurities are present, gypsum may also appear to be red, brown or yellow.
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. [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 .
Empirical Formula: Ca (SO 4)•2 (H 2 O) Environment: Sedimentary evaporite deposits. IMA Status: Valid Species (Pre-IMA) Prehistoric. Locality: Numerous localities worldwide. Naica, Chihuahua, Mexico. Link to MinDat Location Data. Name Origin: From the Greek, gyps meaning "burned" mineral.
The most common sulphate mineral. Found as massive material (including the alabaster variety), clear crystals (the selenite variety) and as parallel fibrous aggregates (the satin spar variety). Typically occurs as colourless to white, transparent crystals, thick …
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).
Gypsum has the same chemical composition as the mineral Anhydrite, but contains water in its structure, which Anhydrite lacks. Many Anhydrite specimens absorb water, transforming into the more common Gypsum.
Chemical Composition. 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 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.".
Gypsum, scientifically known as Calcium Sulfate Dihydrate (CaSO 4 ·2H 2 O), is a naturally occurring mineral primarily formed from the evaporation of ancient bodies of sea water and lakes. It is a soft, transparent to translucent crystal that is typically white or colorless but can take on other hues when impurities are present.
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.
