Sedimentary RocksGypsum Minerals Education Coalition

Sedimentary rocks are commonly grouped according to whether they are clastic biochemical or chemical This works fine except that it is not clear whether some limestones are biochemical or chemical and it is not clear where to put dolostone which is a common rock that often seems to have formed as a result of post burial chemical alteration of limestone Here is the grouping followed on Gypsum is a mineral found in crystal as well as masses called gypsum rock It is a very soft mineral and it can form very pretty and sometimes extremely large colored crystals Massive gypsum rock forms within layers of sedimentary rock typically found in thick beds or layers It forms in lagoons where ocean waters high in calcium and sulfate content can slowly evaporate and be regularly

Sedimentary rock Evaporites BritannicaGypsum Wikipedia

Sedimentary rock Evaporites 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 possible but less Gypsum is a common mineral with thick and extensive evaporite beds in association with sedimentary rocks Deposits are known to occur in strata from as far back as the Archaean eon 10 Gypsum is deposited from lake and sea water as well as in hot springs from

What type of sedimentary rock is gypsum QuoraSedimentary Rock Classification csmgeocsmjmuedu

A sedimentary rock consisting mostly of the mineral gypsum is likely to be an evaporite ie a chemical precipitate crystallized from an ancient sea that dried up under an arid climateIn addition some mineral names also refer to the rock so gypsum the mineral is also gypsum the rock Sometimes we also make a distinction such as dolomite the mineral and dolostone the rock or halite the mineral and rock salt the rock So far so good But now we have to do some mixing and splitting Sedimentary rocks are generally divided into three great categories siliciclastic or
