Sedimentary rocks are formed from pieces of other existing ...Rock gypsum is defined as “a sedimentary rock composed chiefly of the mineral gypsum; it is generally massive, and ranges from coarsely crystalline to finely granular. It often shows disturbed bedding owing to expansion during hydration of the parent anhydrite” ( Neuendorf et al., 2011 ).Chemical Weathering: Weathering is the natural soil formation process by which larger rocks are broken down into smaller particles. Weathering is of three types; physical, chemical and biological.

ROCK GYPSUM . Rock gypsum (a.k.a. gyprock) is a chemical sedimentary rock. It is an example of an evaporite - it forms by the evaporation of water (usually seawater) and the precipitation of dissolved minerals.
