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
Egypt
Discoverer
Dolomieu
Unknown
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.

Dolomite vs Marble Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Dolomite vs Marble characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Marble. Learn more about Dolomite vs Marble in the next section. The interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Marble include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Dolomite and Marble, they have various applications in construction industry. The uses of Dolomite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics, Serves as an oil and gas reservoir rock and that of Marble include As dimension stone.
More about Dolomite and Marble
Here you can know more about Dolomite and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Marble consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Dolomite vs Marble, the texture, color and appearance plays an important role in determining the type of rock. Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Dolomite is Glassy or Pearly and that of Marble is Veined and Shiny. Properties of rock is another aspect for Dolomite vs Marble. The hardness of Dolomite is 3.5-4 and that of Marble is 3-4. The types of Dolomite are Boninite and Jasperoid whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dolomite and Marble is white. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Marble is 0.88 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Dolomite is heat resistant, pressure resistant, wear resistant whereas Marble is heat resistant.
