Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time
Origin
Southern Alps, France

Etymology
From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock
From the Greek marmaros, shining stone and also from the English word marmoreal meaning marble-like

Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

All about Dolomite and Marble Properties
Know all about Dolomite and Marble properties here. All properties of rocks are important as they define the type of rock and its application. Dolomite belongs to Sedimentary Rocks while Marble belongs to Metamorphic Rocks.Texture of Dolomite is Earthy whereas that of Marble is Granular. Dolomite appears Glassy or Pearly and Marble appears Veined and Shiny. The luster of Dolomite is vitreous and pearly while that of Marble is dull to pearly to subvitreous. Dolomite is available in black, brown, green, grey, pink, white colors whereas Marble is available in black, blue, brown, grey, pink, 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 Marble are cemetery markers, commemorative tablets, creating artwork, curling, laboratory bench tops, paper industry, tombstones, used in aquariums, whiting material in toothpaste, paint and paper.
