Halite (NaCl), gypsum (CaSO 4 2H 2 O), and anhydrite (CaSO 4) are the major constituents of the sedimentary rocks rock salt, rock gypsum, and rock anhydrite.


Sedimentary Rocks , Rock Gypsum - Similar to crystalline limestone except the water is supersaturated with gypsum instead of calcite.


Evaporite: Evaporite, any of a variety of individual minerals found in the sedimentary deposit of soluble salts that results from the evaporation of water A brief treatment of evaporite deposits and their constituent minerals follows For full treatment, see sedimentary rock: Evaporit Typically, evaporite.

Reading: Characteristics of Sedimentary Rocks

Reading: Characteristics of Sedimentary Rocks Figure 1 , Gypsum rock is made of the mineral gypsum Chalcedony is made of microcrystalline quartz.

Sedimentary rock

Clastic sedimentary rocks are composed of other rock fragments that were cemented by silicate minerals Clastic rocks are composed largely of quartz, feldspar, rock (lithic) fragments, clay minerals, and mica; any type of mineral may be present, but they in general represent the minerals that exist locally.


Natural Gypsum is obtained in the formation of sedimentary rock, available in more than 85 countri A great quantity of the reserve of superior-quality Gypsum is with the United States, Mexico and Canada The mining of Gypsum is done in 17 states which are the main manufacturers of gypsum.

Sedimentary Rocks Lab (Page 4)

SEDIMENTARY ROCK: Made from sediments , Those listed in blue are chemical sedimentary rocks Breccia , Rock gypsum - CaSO4 * 2 H2O (gypsum).

Sedimentary Rocks

Breccia is a clastic sedimentary rock that is composed of large (over two-millimeter diameter) angular fragments The spaces between the large fragments can be filled with a matrix of smaller particles or a mineral cement which binds the rock together.

Gypsum Rock

Gypsum Rock : Gypsum is an inert, safe mineral that has been used in a variety of applications for centuri It was used as plaster in the Egyptian pyramids.

Gypsite Facts

Gypsum is a soft mineral composed of calcium sulfate dihydrate This sedimentary rock is found throughout the world and one of the most widely used — more than 30 million tons of it is consumed each year.


This gypsum outcrop in the deserts of northern Mexico is fairly non-descript As with most outcrops, a closer look is needed to identify the rock!.

Chemical Sedimentary Rocks

Chemical Sedimentary Rocks , They are typically made up of the minerals halite (calcium chloride, or rock salt) and gypsum (calcium sulfate).


Gypsum 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.

Sedimentary Rocks Lesson #13

Some non-clastic rocks are limestone, chert, dolostone, gypsum, halite (rock salt), diatomite, and chalk Organic sedimentary rocks form from the build up and decay of plant and animal material This usually forms in swamp regions in which there is an abundant supply of growing vegetation and low amounts of oxygen The vegetation builds so.

Selenite a common chemical sedimentary mineral

Selenite is a very common chemical sedimentary mineral It is an evaporate rock which is one of the three types of chemical sedimentary rocks The other two are called Carbonate rocks, and Siliceous rocks.

Sedimentary Rock Classification-How Do You tell One

Sedimentary rock is classified into two groups based on how they form They are clastic and chemical sedimentary rocks , Gypsum

Gypsum is a sedimentary rock and a crystalline mineral “Gypsum is a soft, white to gray, "chalky" mineral composed of calcium sulfate and water,” says.

sedimentary rock

Sedimentary rocks form at or near the earth's surface from the weathered remains of pre-existing rocks or organic debris The term sedimentary rock applies both to consolidated, or lithified sediments (bound together, or cemented) and unconsolidated sediments (loose, like sand) Although there is.

Chemical Sedimentary Rocks

Chemical Sedimentary Rocks Chemical sedimentary rocks form by precipitation of minerals from water , Gypsum Selenite, Limestone, and Limestone with sea creatur.

What is Gypsum?

Natural gypsum, occurs in sedimentary rock formations, and is found in over 85 countri , Gypsum rock is mined or quarried, crushed and ground into a fine powder.

Earlham College

A gypsum rosette is not a rose at all, it is a mineral which crystalizes in a unique rosette growth pattern Their are many varieties, some look remarkably like a rose flower with its pedals open, while others from into beautiful bladed spher.

The types of rock: igneous, metarmorphic and sedimentary

The types of rock: igneous , clastic sedimentary rocks; basically small rock fragments , chemical rocks; these rocks include gypsum and salt.

Gypsum, selenite: The mineral gypsum information and

Detailed description, properties, and locality information guide about the mineral gypsum (selenite) , In enormous deposits and beds in sedimentary rock.

Sedimentary rock gypsum

GYPSUM Amethyst Galleri Gypsum is an evaporative sedimentary rock composed primarily of the mineral gypsum Gypsum beds can be huge, although since it is somewhat water soluble it is.

Rock Gypsum

Rock Gypsum Rock Gypsum is a sedimentary rock in the class known as chemical sedimentary rocks It is formed by the evaporative deposition of gypsum from solution It is commercially very important for the production of plaster of Paris and gypsum wallboard for house construction.

How Is Rock Gypsum Formed?

According to Georgia Southwestern State University, rock gypsum is formed by the evaporation of concentrated solutions like seawater It is a chemical precipitate with a texture ranging from massive or granular to fibrous, depending on the shape and size of the gypsum.

Classification of Sedimentary Rocks

Classification of Sedimentary Rocks by Russell B Travis , Evaporites: Halite and Sylvite, Anhydrite, Gypsum : Phosphatic (rock, grade) Conglomerate:.

Sedimentary Processes and Rocks

Sedimentary Processes and Rocks - Chapter 7 Including, , Most sedimentary rocks are composed of particles which settle , Anhydrite (CaSO 4) - Gypsum without.

Is gypsum metamorphic sedimentary or igneous?

Quartz is actually a silicate mineral that appears in metamorphic, sedimentary, and igneous rocks.

Gypsum Mineral

What is Gypsum? Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur.
