5 Formation
5.1 Formation
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.
Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Picrite vs Shonkinite 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 Picrite and Shonkinite Reserves. Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine. Shonkinite is a rare, dark-coloured and intrusive igneous rock which contains augite and orthoclase feldspar as its primary constituents. 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 Picrite vs Shonkinite information and Picrite vs Shonkinite characteristics in the upcoming sections.

Picrite vs Shonkinite 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. Picrite vs Shonkinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Picrite and Properties of Shonkinite. Learn more about Picrite vs Shonkinite in the next section. The interior uses of Picrite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Shonkinite include Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Picrite and Shonkinite, they have various applications in construction industry. The uses of Picrite in construction industry 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. and that of Shonkinite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Picrite and Shonkinite

Here you can know more about Picrite and Shonkinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Picrite and Shonkinite consists of mineral content and compound content. The mineral content of Picrite includes Biotite, Olivine, Plagioclase, Pyrrhotite and mineral content of Shonkinite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Picrite vs Shonkinite, the texture, color and appearance plays an important role in determining the type of rock. Picrite is available in black, brown, colourless, green, grey, pink, white, yellow colors whereas, Shonkinite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Picrite is Rough and Shiny and that of Shonkinite is Banded and Foilated. Properties of rock is another aspect for Picrite vs Shonkinite. The hardness of Picrite is 6.8 and that of Shonkinite is 5.5-6. The types of Picrite are Oceanite whereas types of Shonkinite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Picrite and Shonkinite is white, greenish white or grey. The specific heat capacity of Picrite is 0.88 kJ/Kg K and that of Shonkinite 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.Picrite is heat resistant whereas Shonkinite is heat resistant, impact resistant, wear resistant.
