Their various sizes, from boulders to clay, is referred to as the sediment grain size. The classification and description of the various clastic rocks appears in the top section of the chart below.

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. Clastic Sedimentary Rocks. Clastic sedimentary rocks may first be classified according to their grain size.

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.”.
