Formation

Formation

Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Lamprophyre 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 Lamprophyre and Dolomite Reserves. Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions. 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 Lamprophyre vs Dolomite information and Lamprophyre vs Dolomite characteristics in the upcoming sections.

Lamprophyre 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. Lamprophyre vs Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lamprophyre and Properties of Dolomite. Learn more about Lamprophyre vs Dolomite in the next section. The interior uses of Lamprophyre 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 Lamprophyre and Dolomite, they have various applications in construction industry. The uses of Lamprophyre in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories 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 Lamprophyre and Dolomite

Here you can know more about Lamprophyre and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lamprophyre and Dolomite consists of mineral content and compound content. The mineral content of Lamprophyre includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Lamprophyre vs Dolomite, the texture, color and appearance plays an important role in determining the type of rock. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Dolomite is available in black, brown, green, grey, pink, white colors. Appearance of Lamprophyre is Dull, Banded and Foilated and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Lamprophyre vs Dolomite. The hardness of Lamprophyre is 5-6 and that of Dolomite is 3.5-4. The types of Lamprophyre are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite 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 Lamprophyre and Dolomite is white. The specific heat capacity of Lamprophyre is 0.84 kJ/Kg K 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.Lamprophyre is heat resistant, impact resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
