Dolomite: A sedimentary rock known as dolostone or dolomite rock
Dolomite, also known as " dolostone " and " dolomite rock ," is a sedimentary rock composed primarily of the mineral dolomite, CaMg (CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater. Dolomite and limestone are very similar

What is Dolomitic Limestone? (with pictures)
Normal limestone is primarily made up of calcite and aragonite, but dolomite forms in the stone when the calcium ions in the calcite part are replaced by magnesium ions — this process is called dolomitization. This type of rock was once referred to as magnesian limestone in the United States Geological Survey publications, but is now known as dolostone, dolomite rock, dolomite limestone, or

Dolomitization
Dolomite occurs by suppression of aragonite or calcite, i.e. dolomitization process. 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 sin-sedimentary. It also forms by dolomitization of limestone as late-diagenetic

Dolomite (rock)
The geological process of conversion of calcite to dolomite is known as dolomitization and any intermediate product is known as dolomitic limestone. [3] [4] The "dolomite problem" refers to the vast worldwide depositions of dolomite in the past geologic record in contrast to the limited amounts of dolomite formed in modern times.

Limestone, Shell, Dolomite | Florida Department of Environmental Protection
Limestone, shell and dolomite are types of marine deposits that have accumulated in Florida over millions of years during times when the state was covered over with seawater or shallow marshes. During this time, limestones formed by chemical deposition and the accumulation of shells from sea creatures. Many invertebrate animals (animals without backbones) take calcite from sea water to

Limestone and Dolomite and their Use in Iron and Steel Plant – IspatGuru
Limestone and lime products are used as fluxing material both in ironmaking and in steelmaking. Basically limestone is used as a slag former, while dolomite is used as a slag former, slag modifier and as a refractory material. The process of iron making is the reduction of iron ore to produce iron.

Dolomitic Limestone
Limestones (dolomitic and dolomite) supply Mg in many soils as well as some primary and secondary minerals. Mg, unlike Ca, is contained in several secondary minerals e.g., montmorillonite, vermiculite, illite, and chlorite. Soils rich in these minerals usually have sufficient available Mg and do not need supplements. Much like Ca, most of the available Mg is exchangeable but usually at a lower

Why is Dolomitic Limestone better
Dolomite is formed through a process called “dolomitization,” where lime mud and limestone are altered by magnesium-rich groundwater, converting calcium into magnesium. Often times it’s difficult to distinguish between Dolomite and regular Limestone due to their very similar appearance, so when in doubt, hydrochloric acid is used to determine whether a rock is Dolomitic or regular.

Dolomite typically has a higher grain density and acoustic velocity than limestones, which affects the response of most porosity wireline logging tools to dolomite rocks. In addition, dolomite reacts more slowly to the presence of acids than does limestone, resulting in uneven responses to acidization treatments.

The Dolomites had their origins in a prehistoric tropical sea. About 250 million years ago, the present-day arc of the Alps was part of the continent Pangea, which was located far to the south, in the Earth’s tropical zone. Given the presence of mollusks, algae, coral and fish, this area saw massive limestone production.

Limestone
Limestone is the raw material for production of lime, primarily known for treating soils, purifying water and smelting copper. Lime is an important ingredient used in chemical industries. [109] Limestone and (to a lesser extent) marble are reactive to acid solutions, making acid rain a significant problem to the preservation of artifacts made from this stone.
