Dolomite, also known as dolostone or dolomite stone, is abundant all over the world.Dolostone is a common sedimentary rock similar to limestone. It is typically a dull gray. It can be identified by scratching the surface and exposing the ...Therefore, the origin of ancient massive dolostone is an important yet unresolved part of the ‘Dolomite Problem’ ( Land, 1985; Machel, 2004; Warren, 2000 ). It is typically a consensus that ancient massive dolostone was generated by the replacement of Ca-carbonate precursors ( Kaczmarek et al., 2017; Land, 1985; Machel, 2004 ).Limestone can be easily recognized in hand specimen or outcrop because of its high solubility in HCl. A drop of such acid placed on the rock will cause it to fizz due to the generation of CO 2 gas. A dolostone, on the other hand, will not fizz until a fine powder is made from the rock or mineral.These rocks can include dolostone, which is the equivalent of limestone but composed primarily of dolomite. Dolostones can vary in texture from fine-grained to coarse-grained, and their color can range from pale gray to various shades of pink, green, or brown. ... Dolomite vs. Limestone: Differences and Comparisons. Dolomite and limestone are ...Limestone. Limestone is a sedimentary rock in the class known as chemical sedimentary rocks.

Dolomite is characterized by its nearly ideal 1:1 stoichiometric ratio of magnesium to calcium. The streak of Limestone and Dolomite is white. The specific heat capacity of Limestone is 0.91 kJ/Kg K and that of Dolomite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Limestone is pressure resistant whereas Dolomite is heat ... probably limestone or dolostone. Limestone and dolostone have the same hardness (3 out of 10 on the Mohs scale, so they scratch easily), and they can look very similar. Calcite, chemical formula CaCO 3, is the main mineral in limestone. Dolomite, chemical formula CaMg(CO 3) 2, is the main mineral in dolostone.In contrast, deeply buried dolostone reservoirs normally show higher porosity compared to limestone because of reduced calcite cementation (Neilson and Oxtoby, 2008). The porosity of shallow-buried (<3500 m) dolostones (e.g., Pliocene-Pleistocene and Miocene dolostone) is typically equal to, or less than, the porosity in age-equivalent ...LIMESTONE VS. DOLOSTONE Limestone vs. dolostone Limestone can be easily recognized in hand specimen or outcrop because of its high solubility in HCl. whereas limestones tend to weather to a white or gray colored rock.

Recent studies of complex carbonate reservoirs indicate that the V p /V s ratio is a function of porosity and in some cases, can differentiate higher-permeability facies.Dolomite forms the main mineral in the bluff-forming rocks along the Mississippi River, such as Granddad Bluff near La Crosse. (Photo by W. Cordua) Dolomite is an abundant mineral in Wisconsin. It is a major rock-forming mineral in the sedimentary dolostones within the Prairie du Chien group (Oneota and Shakopee formations), Sinnepee Group (Platteville, Decorah and Galena Formations) and the ... Dolomite (or Dolostone) is an evaporative sedimentary rock consisting primarily of the mineral dolomite (calcium magnesium carbonate). Since dolomite is less water soluble than calcite, it precipitates first and is also more stable when water containing magnesium penetrates a limestone, resulting in the gradual conversion of a limestone bed into a …Dolostone – Very similar to limestone, but made of dolomite instead of calcite. Slightly harder and often has a reddish hue. Slightly harder and often has a reddish hue. Diatomite – Often confused for chalk, but is very powdery and made of tiny silica particles instead of calcium carbonate.Siliceous Limestone: disseminated silica Cherty Limestone: containing chert nodules Etc.
