dolomite Formation, Structure, Properties, Uses, Facts ...

Dolomite crystals are colourless, white, buff-coloured, pinkish, or bluish. Granular dolomite in rocks tends to be light to dark gray, tan, or white. Dolomite crystals range from transparent to translucent, but dolomite grains in rocks are typically translucent or

Dolomite (mineral) - Wikipedia

The mineral dolomite crystallizes in the trigonal-rhombohedral system. It forms white, tan, gray, or pink crystals. Dolomite is a double carbonate, having an alternating structural arrangement of calcium and magnesium ions. Unless it is in fine powder form, it does not rapidly dissolve or effervesce (fizz) in cold dilute hydrochloric acid as calcite does. Crystal twinning is common. Solid solution exists between dolomite, the iron-dominant ankerite and the manganese-dominant kutnohorite

Characteristics of deep-marine dolomite Journal of ...

The dolomite is commonly nonstoichiometric (avg. 56% CaCO 3) and poorly ordered. Globally, it does not change in stoichiometry or order with depth or age. Dolomite in deep-marine sediments does not originate from unusual or regionally important conditions. It entered the sediments early, most probably as a chemical precipitate from pore waters.

Genetic types and distinguished characteristics of ...

There are clear boundaries in geochemical characteristics and evolving clues between the six different types of dolomite, however, a lot of dolomite isn’t of single genesis, for example, the early low-temperature dolomite could receive transformation by burial dolomitization additionally, and the dolomite with crystal grain texture formed during burial stage could receive transformation by structural-hydrothermal dolomitization, which greatly increase the geochemical complexity of dolomite.

Dolomite is an anhydrous carbonate mineral. It is a double carbonate of calcium and magnesium (CaCO3.MgCO3). It is one of the important raw materials used in production of iron and steel. Dolomite contains theoretically 54.35 % of CaCO3 and 45.65 % of MgCO3 or 30.41 % of CaO, 21.86 % of MgO, and 47.73 % of CO2.
