Dolomite in Northern Norway (Trollholmsund) which was once chalk, but the original material has been replaced with dolomite.

Dolomite (rock) - Wikipedia

Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO3)2. It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 65 million years in age). The first geologist to distinguish dolomite rock from limestone

Sedimentary rock - Limestones and dolomites | Britannica

Sedimentary rock - Sedimentary rock - Limestones and dolomites: Limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO3) and dolomite (CaMg[CO3]2). Almost all dolomites are believed to be produced by recrystallization of preexisting limestones, although the exact details of this dolomitization process ...

Dolomite - University of California, Berkeley

Such rocks form vast deposits; in Italy, the Alpine range known as the Dolomites is almost entirely composed of dolomite. However, unlike calcite, dolomite's sedimentary origin is enigmatic. Although it is the most stable carbonate mineral where magnesium is abundant in the marine environment, it is unknown as a primary mineral.

Rock Types - Dolomite

Mineralogy: Contains a high proportion of dolomite (the mineral and the rock have the same name). Detrital minerals and secondary silica (chert) may be present. Field relations: Dolomites are usually interbedded with other limestone s and are commonly associated salt and gypsium deposits.

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 magnesium-rich ground water. The specimen shown above is about four inches (ten centimeters) across.

Sedimentary Rocks - Pitt

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.
