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
Teschenite is coarse- to fine-grained, dark-coloured intrusive igneous rock that usually occurs in sills, dikes and irregular masses and is always altered to some extent

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Teschenite 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 Teschenite 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 Teschenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Boninite and Properties of Teschenite. Learn more about Boninite vs Teschenite in the next section. The interior uses of Boninite include Decorative aggregates, Homes and Kitchens whereas the interior uses of Teschenite include Countertops, Decorative aggregates, Entryways, Homes and Interior decoration. Due to some exceptional properties of Boninite and Teschenite, 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 Teschenite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Boninite and Teschenite
Here you can know more about Boninite and Teschenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Boninite and Teschenite consists of mineral content and compound content. The mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite and mineral content of Teschenite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Boninite vs Teschenite, 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, Teschenite is available in dark grey to black colors. Appearance of Boninite is Dull and Soft and that of Teschenite is Veined and Shiny. Properties of rock is another aspect for Boninite vs Teschenite. Hardness of Boninite and Teschenite is 7. The types of Boninite are Basalt whereas types of Teschenite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Boninite is white while that of Teschenite is black. The specific heat capacity of Boninite is 0.84 kJ/Kg K and that of Teschenite is 0.79 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 Teschenite is impact resistant, pressure resistant, wear resistant.
