Limestones and dolomites. Chuck, There is also … Limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO 3) and dolomite (CaMg[CO 3] 2).Almost all dolomites are believed to be produced by recrystallization of preexisting limestones, although the exact details of this dolomitization process continue to be debated.

The metamorphism of siliceous dolomitic limestone is considered with the aid of a composition tetrahedron which suggests that the changes may be referred to thirteen steps or grades of increasing decarbonation, taking place at successively higher temperatures at any given pressure.

Cite as. Depending on whether the alternation occurs during metamorphism, contact metamorphism can be divided into heat contact metamorphism and contact alternation metamorphism. Pure marble is the result of metamorphism of a very pure limestone or dolomite. Other Lower Cretaceous limestones generally are too soft for use as a quality aggregate and insufficiently pure for use as chemical grade stone. True marble is formed by recrystallization of limestone or dolomite due to increased heat and pressure (regional metamorphism) or increased heat accompanying igneous events (thermal metamorphism).

Hardness – hard, although component mineral is soft (calcite is 3 on Moh’s scale of hardness) The first is modally dominated by dolomite (CaMg(CO3)2), the second by calcite (CaCO3) and there is a complete gradation between the pure dolomite and limestone “end members” indicated by the rock names, calcitic dolomite, dolomitic limestone, magnesian limestone. When carbonates are altered by contact metamorphism the industrial mineral quality of the rock can be affected. Fine limestone has been quarried in Vermont since colonial days. 103.227.176.10. Morrison pendant, Sierra Nevada, California, USA. In some places the limestone is in thin beds intercalated between other sediments, as at Mill City, Nev.; in other places limestone makes up most of, the beds for a thousand feet or more in thickness, as at Pine Creek, near Bishop, Calif.

There are a number of metamorphosed limestone or marble deposits in America that are pure enough to be used for special purposes. As expected in such an environment, volcanic rocks, folding and regional metamorphism are absent as a general rule. The only way to know is to prospect! limestones are dolomite-free, but Ordovician and Sil­ urian limestones can contain some dolomite.

As the rocks often also contain variable amounts of quartz they are sometimes referred to as siliceous dolomites and siliceous limestones. pp 225-255 | The deposit is in the Gambier Limestone, an Oligo-Miocene marine formation consisting almost wholly of bryozoal and shell remains. Current uses for limestone in Victoria, in descending order of tonnage consumed, are: 1. cement manufacture 2. road-making 3. agriculture 4. lime manufacture 5. and minor amounts for paper, glass and steel-making. At Caroline, the limestone is exceptionally white, contains a significant silt-sized and finer carbonate fraction and is low in deleterious non-carbonate materials such as sand, silt, clay, dolomite, flint, iron and manganese.
