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
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Boninite vs Metapelite 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 Metapelite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Boninite and Properties of Metapelite. Learn more about Boninite vs Metapelite in the next section. The interior uses of Boninite include Decorative aggregates, Homes and Kitchens whereas the interior uses of Metapelite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Boninite and Metapelite, 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 Metapelite include Cement manufacture, Construction aggregate, For road aggregate.
More about Boninite and Metapelite
Here you can know more about Boninite and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Boninite and Metapelite consists of mineral content and compound content. The mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite and mineral content of Metapelite includes Albite, Chlorite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Boninite vs Metapelite, the texture, color and appearance plays an important role in determining the type of rock. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas, Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. Appearance of Boninite is Dull and Soft and that of Metapelite is Banded. Properties of rock is another aspect for Boninite vs Metapelite. The hardness of Boninite is 7 and that of Metapelite is 5-6. The types of Boninite are Not Available whereas types of Metapelite are Not Available. 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 Metapelite is unknown. The specific heat capacity of Boninite is Not Available and that of Metapelite is 0.72 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 Metapelite is heat resistant, impact resistant, pressure resistant.
