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.
Picrite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Carbonatite vs Picrite 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 Picrite Reserves. Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals. Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine. 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 Picrite information and Carbonatite vs Picrite characteristics in the upcoming sections.

Carbonatite vs Picrite 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 Picrite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Carbonatite and Properties of Picrite. Learn more about Carbonatite vs Picrite in the next section. The interior uses of Carbonatite include Decorative aggregates and Interior decoration whereas the interior uses of Picrite include Countertops, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Carbonatite and Picrite, 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 Picrite include As a sintering agent in steel industry to process iron ore, Cement manufacture, For road aggregate, Manufacture of magnesium and dolomite refractories, Roadstone, Used for flooring, stair treads, borders and window sills..

More about Carbonatite and Picrite

Here you can know more about Carbonatite and Picrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Carbonatite and Picrite consists of mineral content and compound content. The mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite and mineral content of Picrite includes Biotite, Olivine, Plagioclase, Pyrrhotite. You can also check out the list of all Igneous Rocks. When we have to compare Carbonatite vs Picrite, 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, Picrite is available in black, brown, green, grey, pink, white, yellow colors. Appearance of Carbonatite is Dull, Banded and Foilated and that of Picrite is Rough and Shiny. Properties of rock is another aspect for Carbonatite vs Picrite. The hardness of Carbonatite is 3 and that of Picrite is 6.8. The types of Carbonatite are Carbonatite whereas types of Picrite are Oceanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Carbonatite is white while that of Picrite is white, greenish white or grey. The specific heat capacity of Carbonatite is 0.51 kJ/Kg K and that of Picrite 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.Carbonatite is heat resistant, pressure resistant, water resistant whereas Picrite is heat resistant.
