SEDIMENTARY ROCK: Made from sediments consolidated at the earth's surface. The sediments are deposited at the earth's surface by water, wind, glacial ice, or bio-chemical processes. Typically the sediments are deposited in layers under COOL conditions [thereby distinguishing it from a layered volcanic rock (TUFF)].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.
