What class of sedimentary rock is gypsum?

chemical sedimentary rocks
Rock Gypsum is a sedimentary rock in the class known as chemical sedimentary rocks. It is formed by the evaporative deposition of gypsum from solution. It is commercially very important for the production of plaster of Paris and gypsum wallboard for house construction.

What is the name of a gypsum rock?

Gypsum, also known as calcium sulfate hydrate, is a naturally occurring mineral found in layers of sedimentary rock all over the world.

Is gypsum A chemical sedimentary rock?

CHEMICAL SEDIMENTARY ROCKS – formed when dissolved substances precipitate from water to form sediments and eventually rock; include salts such as ROCK SALT, GYPSUM, and LIMESTONE, and biochemically mediated rocks such as peat, and reef rock (an organic limestone).

What is gypsum stone?

Gypsum is a naturally occurring stone, a metallic salt of calcium. It commonly forms as an evaporite from the dissolution of limestone by exposure to sulphuric acid from volcanic activity. Primary deposit gypsums are characterized by a loose crystalline structure and high solubility in water.

What is gypsum chemically?
