Gypsum sedimentary rock.

Gypsum is an important rock-forming mineral in evaporite deposits of chemical sedimentary rocks, where they may be associated with halite, and in carbonates in association with barite. Gypsum deposition may form massive and stratified beds that are several meters thick, usually in association with beds of limestone, red clays, halite and other ... As there is a close relation between rocks and landforms, rocks and soils, a geographer requires basic knowledge of rocks. There are many different kinds of rocks which are grouped under three families on the basis of their mode of formation. They are: (i) Igneous Rocks — solidified from magma and lava; (ii) Sedimentary Rocks — the result ofSedimentary rock - Evaporites, Deposits, Minerals: Evaporites are layered crystalline sedimentary rocks that form from brines generated in areas where the amount of water lost by evaporation exceeds the total amount of water from rainfall and influx via rivers and streams. The mineralogy of evaporite rocks is complex, with almost 100 varieties …Sedimentary rock - Clastic, Chemical, Organic: There are many different systems of classifying sandstones, but the most commonly used schemes incorporate both texture (the presence and amount of either interstitial matrix—i.e., clasts with diameters finer than 0.03 millimetre—or chemical cement) and mineralogy (the relative amount of quartz and the …

Limestones. The most common chemical sedimentary rock is limestone. Composed mostly of the mineral calcite (CaCO 3), limestones are usually formed by biochemical processes in shallow seawater. Coral and algae are especially important limestone builders. Oolitic limestones form in ocean shallows from the accumulation of oolites, sand‐sized spheres …

Gypsum grains in the White Sands National Monument are different. They are not the product of disintegration of rocks.
