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.
Rock gypsum (a.k.a. gyprock) is a chemical sedimentary rock. What type of sedimentary rock is rock salt? Rock Salt is a chemical sedimentary rock that forms from the evaporation of ocean or saline lake waters. It is also known by the mineral name "halite." It is rarely found at Earth's surface, except in areas of very arid climate.
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.
As a rock, gypsum is a 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 replenished with new sources of water. The result is the accumulation of large beds of sedimentary gypsum.
Gypsum is mined from sedimentary rock formations around the world. It takes the form of crystals which can at times be found projecting from rock – leading to its old English name of the Spear Stone. The largest gypsum quarries in Europe are found in France, Germany, Italy, Poland, Spain, and the UK. There is also evidence of gypsum dunes on ...
Sedimentary rocks are formed by the lithification of inorganic and/or organic sediments, or as chemical precipitates. There are two types of sedimentary rocks: Clastic and Chemical Clastic sedimentary rocks form when existing parent rock material is weathered, fragmented, transported, and deposited in layers that compact,

Sulfate minerals are delicate and occur near the Earth's surface in sedimentary rocks such as limestone, gypsum rock, and rock salt. Sulfates tend to live near oxygen and water. There is a whole community of bacteria that make their living by reducing sulfate to sulfide where oxygen is absent.
The table below includes specific environments where various types of sediments are deposited and common rocks, structures, and fossils that aid in deducing the depositional environment from examining a sedimentary rock outcrop. Although this is not a complete list, it is a good introduction to depositional environments. Continental; Transitional
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). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.
ROCK GYPSUM . Rock gypsum (a.k.a. gyprock) is a chemical sedimentary rock. It is an example of an evaporite - it forms by the evaporation of water (usually seawater) and the precipitation of dissolved minerals. Rock salt & rock gypsum often occur together in evaporitic successions. Rock gypsum is composed of the mineral gypsum (CaSO 4 ·2H 2 O - hydrous calcium sulfate).
Gypsum is a sedimentary rock. However, it is a special kind of sedimentary rock called a chemical sedimentary rock. This means it is not the cemented...

Keys to the Identification of Sedimentary Rocks. Want to see an example of a sedimentary rock, and you know its name (or all you know is its name)? This is the place. The specimens vary a lot in their quality. We did not try to find the best, most pristine examples available. Instead we looked for representative specimens, many of which just ...

As a rock, gypsum is a 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 replenished with new sources of water. The result is the accumulation of large beds of sedimentary gypsum.
This is a common way for chemical sedimentary rocks to form and the rocks are commonly called evaporites. They are typically made up of the minerals halite (calcium chloride, or rock salt) and gypsum …

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 one of the more common minerals in sedimentary environments. It is a major rock forming mineral that produces massive beds, usually from precipitation out of highly saline waters. Since it forms easily from saline water, gypsum can have many inclusions of …

Occurrence of Gypsum. Gypsum is a not unusual mineral, with thick and good sized evaporite beds in affiliation with sedimentary rocks. Deposits are recognized to occur in strata from as a long way lower back as the Archaean eon. It is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate answers in veins.
Is Rock Gypsum sedimentary rock? As a rock, gypsum is a sedimentary rock, typically found in thick beds or layers. The result is the accumulation of large beds of sedimentary gypsum. Because it is deposited in this environment, it is common for gypsum to be associated with rock salt and sulfur deposits.
Gypsum is readily identified by its softness (a fingernail scratches it). Gypsum comes as clear crystals that display one perfect cleavage (selenite), as blocks of featureless white rock (alabaster), and as silky fibrous blocks (satin spar). Halite (next page) breaks into cubes (three cleavages at right angles) and tastes like table salt.
Some uses of this type of rock are provided below. Limestone is used to make cement. Limestone and sandstone are used for building stones. Quartz is a type of sedimentary rock which is used to make glass. Rock gypsum is used to make plaster. Natural gas, oil, coal, and uranium, and other energy resources are formed in and come from sedimentary ...

TYPES OF DETRITAL SEDIMENTARY ROCKS
Gigantic gypsums are formed beneath layers of sedimentary rock, along with halite, anhydrite, sulfur, calcite, and dolomite. Thick beds and layers of rocks are commonplace for finding gypsum. Ocean water is high in calcium and sulfate minerals so gypsum is also found in lagoons as the water in the ocean can slowly evaporate and be replenished ...
