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(CO 3) 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 66 ...
Dolomite is usually found in rocks older than 100 million years, meaning that this mineral take a long time to form. According to the researchers, this slow growth rate can be attributed to how ...
Dolomite (/ ˈ d ɒ l. ə ˌ m aɪ t, ˈ d oʊ. l ə-/) is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO 3) 2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite (see Dolomite (rock) ).
The rock formation consists of three members: lower shale, middle dolomite, and upper shale. The shales were deposited in relatively deep anoxic marine conditions, and the dolomite was deposited as a coastal carbonate bank during a time of shallower, well-oxygenated water. The middle dolomite member is the principal oil reservoir, roughly two ...

The discovery of dolomite rock, or dolostone, was first published in 1791 [8] and has been found across the Earth's crust from various different time periods. [9] Because the rock is made of calcium , magnesium , and carbonate ions, the mineral crystalline structure can be visualized similar to calcite and magnesite . [ 10 ]
Main Dolomite (German: Hauptdolomit, Hungarian: Fődolomit, Italian: Dolomia Principale) is a lithostratigraphic unit in the Alps of Europe. Formation was defined by K.W. Gümbel in 1857. Middle to Late Triassic sedimentary record in the Alpine realm is characterized by presence of various masses of dolomitic rock formations.
The Boyle Group, also known as the Boyle Limestone or Boyle Dolomite is a geologic group found in Kentucky. It dates back to the Devonian period. The Boyle is bound by two unconformities. The one at the top is the Taghanic unconformity and the one at the bottom is the Wallbridge Unconformity. The New Albany Shale uncomfortably lies on top of ...
