Rock gypsum (gyprock) Sedimentary rocks form by the solidification of loose sediments Loose sediments become hard rocks by the processes of deposition, burial, compaction, dewatering, and cementation There are three categories of sedimentary rocks: 1) Siliciclastic sedimentary rocks form by the solidification of sediments produced by weathering & erosion of any previously existing rocks.

Gypsum as a rock type is an aggregate of gypsum crystals Gypsum is an evaporite and is usually associated with other evaporite minerals like halite and anhydrite Gypsum occurs in different forms: massive alabaster, fibrous satin spar, selenite crystals Gypsum is an important industrial mineral It is used mostly in the construction industry^.

Image 5 is a thick deposit of rock gypsum within a sequence of sedimentary rocks exposed in the Rocky Mountains of Colorado Development of such a thick layer of evaporite rock would have required continuous evaporation of an arm of the ocean over a long period of time.

Jan 21, 2019· Sedimentary rocks are the second great rock class Whereas igneous rocks are born hot, sedimentary rocks are born cool at the Earth's surface, mostly under water They usually consist of layers or strata; hence they are also called stratified rocksDepending on what they're made of, sedimentary rocks fall into one of three typ.

Evaporites - chemical sedimentary rocks that form through the evaporation of water; usually found in dry lake beds (playas) Rock salt, rock gypsum, are two exampl Coal - organic sedimentary rock composed of the remains of plant material Various grades of coal include peat, lignite, bituminous coal, and anthracite coal.

Clastic: basic sedimentary rock which is composed of clasts: little pieces of broken-up rock which are joined together as a result of compaction and cementation Chemical: these are often formed as a result of repeated flooding and evaporation When water evaporates it leaves a layer of dissolved minerals behind Deposits of salt and gypsum are characteristic examples of these process.

Nov 04, 2011· What is the Difference Between Gypsum and Limestone? Gypsum is a hydrated calcium sulfate mineral with the molecular formula CaSO 4 2H 2 O and limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral and mollusks Therefore, the key difference between gypsum and limestone is that calcium sulfate is the main constituent in gypsum.
