Detailed explanation-1: -Chemical sedimentary rock forms when mineral constituents in solution become supersaturated and inorganically precipitate. Common chemical sedimentary rocks include oolitic limestone and rocks composed of evaporite minerals, such as halite (rock salt), sylvite, baryte and gypsum.

Detailed explanation-2: -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).

Detailed explanation-3: -Chemical sedimentary rocks form by chemical precipitation that begins when water traveling through rock dissolves some of the minerals. These minerals are carried away from their source and eventually redeposited, or precipitated, when the water evaporates away.

Detailed explanation-4: -Inorganic chemical sedimentary rocks are formed when minerals precipitate out of an aqueous solution, usually due to water evaporation.

Detailed explanation-5: -3) Chemically precipitated (chemical) sedimentary rocks are those such as halite and gypsum, and some limestones, which form direct precipitation (crystallization) of the dissolved ions in the water.
