A. Those formed chemically: Mineral-containing water evaporates at the mouths of springs or salt lakes, forming stalactites and stalagmites which are the deposits of lime left over by the lime-mixed water as it evaporates in the underground caves.

Gypsum is considered both a sedimentary rock and a mineral. Its chemical formula is CaSO 4 ∙2H 2 O. Because gypsum formed when ancient seas evaporated in Oklahoma during Permian time (299-251 million years ago), geologists classify it as an evaporite.Western Oklahoma has many large deposits of gypsum totaling trillions of tons (Figure 1).

It forms in lagoons where ocean waters high in calcium and sulfate content can slowly evaporate and be regularly replenished with new sources of water. The result is the accumulation of large beds of sedimentary gypsum. Gypsum is commonly associated with rock salt and sulfur deposits. arrow right.

Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4).

This is seen in its chemical formula is CaSO 4 2H 2 0. When gypsum is heated and the water within the mineral is evaporated out, gypsum turns into a chalk or plaster, known as plaster of Paris.Gypsum is calcium sulfate dihydrate (CaSO 4 2H 2 O). It is a natural mineral that occurs in certain types of sedimentary rocks. Gypsum forms when water evaporates in mineral-rich marine soil environments. Over long periods of time, evaporation brings more minerals to the soil surface, eventually forming a solid deposit.Aug 9, 2023 · Gypsum rocks are sedimentary rocks made up of sulfate mineral and formed as the result of evaporating sea water in massive prehistoric basins.
