Definition

Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

Etymology

From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock

From a sediment left after the evaporation

Formation

Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

All about Dolomite and Evaporite Properties

Know all about Dolomite and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Dolomite and Evaporite belong to Sedimentary Rocks.Texture of Dolomite is Earthy whereas that of Evaporite is Earthy. Dolomite appears Glassy or Pearly and Evaporite appears Glassy, Vesicular and Foilated. The luster of Dolomite is vitreous and pearly while that of Evaporite is subvitreous to dull. Dolomite is available in black, brown, green, grey, pink, white colors whereas Evaporite is available in green, grey, silver, white colors. The commercial uses of Dolomite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo) and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
