Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.
Origin
Southern Alps, France

Discoverer
Dolomieu
Unknown
Etymology
From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock
From English word serpentinization.

Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Dolomite vs Serpentinite 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 Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Serpentinite. Learn more about Dolomite vs Serpentinite in the next section. The interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Dolomite and Serpentinite, 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 Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Dolomite and Serpentinite
Here you can know more about Dolomite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Serpentinite consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Dolomite vs Serpentinite, 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, Serpentinite is available in black, brown, colourless, green, grey, white colors. Appearance of Dolomite is Glassy or Pearly and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Dolomite vs Serpentinite. The hardness of Dolomite is 3.5-4 and that of Serpentinite is 3-5. The types of Dolomite are Boninite and Jasperoid whereas types of Serpentinite are Jadeitite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dolomite is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Serpentinite is 0.95 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 Serpentinite is heat resistant.
