Dolomite is a mineral and a rock that has a unique saddleshaped crystal. It is made up of calcium magnesium carbonate and most likely exists in sedimentary or metamorphic rocks. Dolomite is commonly found in many European areas, Canada, and Africa.
All You Need to Know About Dolomite for Kitchen Countertops
Mar 20, 2019· Also known as dolostone, dolomite is a type of sedimentary rock that consists primarily of the mineral known as dolomite. Around the world, this rock can be found in sedimentary basins where it is formed as a result of limestone and lime mud coming into contact with groundwater rich in magnesium. Dolomite is very similar in composition to limestone.
Sedimentary Rock Classification
When clay is deposited it becomes the rock shale Calcite (CaCO 3) is a mineral with rhombohedral cleavage that reacts with dilute hydrochloric acid. As a sedimentary mineral it exists either as micrite (" lime mud", that is as fine grained as clay) or large pieces such as animal skeletons. These together form the rock limestone.

A mainstream theory suggests that 65 million years ago, pressures beneath the Earth's surface reached a climax, pushing through the ground with enough force to create the Rocky Mountains, the Black Hills, and a stream of molten magma that intruded into sedimentary rock layers, thus forming this monument.
Types of Sedimentary Rock ThoughtCo
Dolomite rock is a white or lightly tinted sedimentary rock consisting largely of the calciummagnesium carbonate mineral dolomite. ThoughtCo / Andrew Alden Dolomite rock, also sometimes called dolostone, is usually a former limestone in which the mineral calcite is altered to dolomite.
Dolomite | Definition of Dolomite by Lexico
A sedimentary rock formed chiefly of dolomite. More example sentences 'In the Mesozoic, and into the Paleocene, limestone and dolomite interbedded with shale, clay and anhydrite prevailed in a more restricted, shallow marine to lagoonal environment.'

Sedimentary Rocks | Pictures, Characteristics, Textures, Types
Dolomite (also known as "dolostone" and "dolomite rock") is a chemical sedimentary rock that is very similar to limestone. It is thought to form when limestone or lime mud is modified by magnesiumrich ground water. The specimen shown above is about four inches (ten centimeters) across.
What is the difference between dolomite and limestone? Quora
Mar 26, 2018· Limestone vs Dolomite Both limestone and dolomite are types of rock made of carbonate precipitation. The patterns of the way they behave chemically are almost the same with varied intensities. However, the structure and the formation of these rock...
What type of rock is marble and dolomite? igneous ...
Dec 31, 2007· Best Answer: sedimentary rocks are caused by lots of grains being compressed together. Igneous rock is caused by lava above ground, and metamorphic is when either type of rock changes due to high temperature and pressure. Dolomite has crystals so is sedimentary. Marble is limestone that has undergone high pressure and temperature.
Kona Dolomite | Roth's Rocks
Kona Dolomite History: Kona Dolomite is an ancient rock in which formations of fossil stromatolite (bluegreen algae) occur. The stone is between to billion years old. These stromatolite formations are from some of the first life on earth. These fossil formations are found in the lower eras of the Middle Precambrian Period.
Dolomite an overview | ScienceDirect Topics
The Origin of Dolomite. Dolomitization occurs in nature or even in untied limestone deposit or in already solid limestone rocks. Dolomites that occur in the untied deposit are called early diagenetic or sinsedimentary. It also forms by dolomitization of limestone as latediagenetic or postsedimentary events.
Dolomite: Mineral information, data and localities.
Dolomite and ferroan dolomite occur frequently as pseudomorphs after calcite and also after aragonite. Rarely pseudomorphic after cerussite, baryte and fluorite. Several species have been recognized as incrustation or substitution pseudomorphs after dolomite crystals.
Dolomites |
Dolomite is a fairly soft mineral that occurs as crystals as well as in large sedimentary rock beds several hundred feet thick. The crystals — usually rhombohedral in shape — are transparent to translucent and are colorless, white, reddishwhite, brownishwhite, gray, or sometimes pink.

Chemical Sedimentary Rocks CliffsNotes
Chemical Sedimentary Rocks. 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 of chemically precipitated calcite that develop in the tidal zone.
DOLOMITE (Calcium Magnesium Carbonate)
Dolomite, which is named for the French mineralogist Deodat de Dolomieu, is a common sedimentary rockforming mineral that can be found in massive beds several hundred feet thick. They are found all over the world and are quite common in sedimentary rock sequences. These rocks are called appropriately enough dolomite or dolomitic limestone.
