Eclogite vs Dolomite

Add ⊕
1 Definition
1.1 Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

5 Formation
5.1 Formation
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Eclogite vs Dolomite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Eclogite and Dolomite Reserves. Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature. Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Eclogite vs Dolomite information and Eclogite vs Dolomite characteristics in the upcoming sections.

Eclogite vs Dolomite 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. Eclogite vs Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Eclogite and Properties of Dolomite. Learn more about Eclogite vs Dolomite in the next section. The interior uses of Eclogite include Decorative aggregates and Interior decoration whereas the interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Eclogite and Dolomite, they have various applications in construction industry. The uses of Eclogite in construction industry include Not yet used and that of Dolomite 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.

More about Eclogite and Dolomite

Here you can know more about Eclogite and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Dolomite consists of mineral content and compound content. The mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite and mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Dolomite, the texture, color and appearance plays an important role in determining the type of rock. Eclogite is available in black, brown, colourless, green, grey, pink, white colors whereas, Dolomite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Eclogite vs Dolomite. Hardness of Eclogite and Dolomite is 3.5-4. The types of Eclogite are Not Available whereas types of Dolomite are Boninite and Jasperoid. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite and Dolomite is white. The specific heat capacity of Eclogite is Not Available and that of Dolomite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Eclogite is heat resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
