Definition
Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt
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

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

Epidosite vs Boninite 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. Epidosite vs Boninite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Epidosite and Properties of Boninite. Learn more about Epidosite vs Boninite in the next section. The interior uses of Epidosite include Decorative aggregates, Floor tiles, Homes, Hotels and Interior decoration whereas the interior uses of Boninite include Decorative aggregates, Homes and Kitchens. Due to some exceptional properties of Epidosite and Boninite, they have various applications in construction industry. The uses of Epidosite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone and that of Boninite 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.
More about Epidosite and Boninite
Here you can know more about Epidosite and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Epidosite and Boninite consists of mineral content and compound content. The mineral content of Epidosite includes Olivine, Plagioclase, Pyroxene and mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite. You can also check out the list of all Igneous Rocks. When we have to compare Epidosite vs Boninite, the texture, color and appearance plays an important role in determining the type of rock. Epidosite is available in black, brown, light to dark grey colors whereas, Boninite is available in bluish - grey, brown, colourless, green, grey colors. Appearance of Epidosite is Dull and Soft and that of Boninite is Dull and Soft. Properties of rock is another aspect for Epidosite vs Boninite. The hardness of Epidosite is 6 and that of Boninite is 7. The types of Epidosite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite whereas types of Boninite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Epidosite is white to grey while that of Boninite is white. The specific heat capacity of Epidosite is Not Available and that of Boninite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Epidosite is heat resistant, pressure resistant, wear resistant whereas Boninite is heat resistant, impact resistant, pressure resistant, wear resistant.
