Felsite vs Boninite


Definition

Definition
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction  
Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition

Formation

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.  
Felsite 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.

Boninite vs Felsite 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 Boninite and Felsite Reserves. Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction. Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition. 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 Boninite vs Felsite information and Boninite vs Felsite characteristics in the upcoming sections.

Boninite vs Felsite 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. Boninite vs Felsite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Boninite and Properties of Felsite. Learn more about Boninite vs Felsite in the next section. The interior uses of Boninite include Decorative aggregates, Homes and Kitchens whereas the interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Boninite and Felsite, they have various applications in construction industry. The uses of Boninite 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 Felsite include Arrowheads, Cutting tool, Knives, Scrapers, Spear points.

More about Boninite and Felsite

Here you can know more about Boninite and Felsite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Boninite and Felsite consists of mineral content and compound content. The mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite and mineral content of Felsite includes Feldspar, Iron Oxides. You can also check out the list of all Igneous Rocks. When we have to compare Boninite vs Felsite, the texture, color and appearance plays an important role in determining the type of rock. Boninite is available in bluish - grey, brown, green, grey colors whereas, Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Boninite is Dull and Soft and that of Felsite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Boninite vs Felsite. The hardness of Boninite is 7 and that of Felsite is 5-5.5. The types of Boninite are Basalt whereas types of Felsite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Boninite and Felsite is white. The specific heat capacity of Boninite is 0.84 kJ/Kg K and that of Felsite 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.Boninite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Felsite is heat resistant, impact resistant.
