5.1 Formation

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

Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

All about Dolomite and Oolite Properties

Know all about Dolomite and Oolite properties here. All properties of rocks are important as they define the type of rock and its application. Dolomite and Oolite belong to Sedimentary Rocks.Texture of Dolomite is Earthy whereas that of Oolite is Clastic or Non-Clastic. Dolomite appears Glassy or Pearly and Oolite appears Rounded and Rough. The luster of Dolomite is vitreous and pearly while that of Oolite is pearly to shiny. Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow 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 Oolite are creating artwork, jewelry, used in aquariums.
