Formation

Formation

Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.
Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

Carbonatite vs Schist 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 Carbonatite and Schist Reserves. Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals. Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation. 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 Carbonatite vs Schist information and Carbonatite vs Schist characteristics in the upcoming sections.

Carbonatite vs Schist 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. Carbonatite vs Schist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Carbonatite and Properties of Schist. Learn more about Carbonatite vs Schist in the next section. The interior uses of Carbonatite include Decorative aggregates and Interior decoration whereas the interior uses of Schist include Decorative aggregates, Floor tiles and Interior decoration. Due to some exceptional properties of Carbonatite and Schist, they have various applications in construction industry. The uses of Carbonatite 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 and that of Schist include As dimension stone, Building houses or walls, Cement manufacture, For road aggregate, Roadstone.

More about Carbonatite and Schist

Here you can know more about Carbonatite and Schist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Carbonatite and Schist consists of mineral content and compound content. The mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite and mineral content of Schist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc. You can also check out the list of all Igneous Rocks. When we have to compare Carbonatite vs Schist, the texture, color and appearance plays an important role in determining the type of rock. Carbonatite is available in black, brown, green, grey, pink, white colors whereas, Schist is available in black, blue, brown, dark brown, green, grey, silver colors. Appearance of Carbonatite is Dull, Banded and Foilated and that of Schist is Layered and Shiny. Properties of rock is another aspect for Carbonatite vs Schist. The hardness of Carbonatite is 3 and that of Schist is 3.5-4. The types of Carbonatite are Carbonatite whereas types of Schist are Mica Schists, Calc-Silicate Schists, Graphite Schists, Blueschists, Whiteschists, Greenschists, Hornblende Schist, Talc Schist, Chlorite Schist, Garnet Schist, Glaucophane schist.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Carbonatite and Schist is white. The specific heat capacity of Carbonatite is 0.51 kJ/Kg K and that of Schist is 0.70 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Carbonatite is heat resistant, pressure resistant, water resistant whereas Schist is impact resistant, pressure resistant, water resistant.
