Definition
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs
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

Features
Has High structural resistance against erosion and climate, Host rock for Diamond, Very fine grained rock
Available in Lots of Colors and Patterns, High Mg content, Is one of the oldest rock
Archaeological Significance
Formation
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

Adakite 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. Adakite vs Boninite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Adakite and Properties of Boninite. Learn more about Adakite vs Boninite in the next section. The interior uses of Adakite include Decorative aggregates, Floor tiles, Homes, Hotels and Kitchens whereas the interior uses of Boninite include Decorative aggregates, Homes and Kitchens. Due to some exceptional properties of Adakite and Boninite, they have various applications in construction industry. The uses of Adakite 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 Adakite and Boninite
Here you can know more about Adakite and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adakite and Boninite consists of mineral content and compound content. The mineral content of Adakite 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 Adakite vs Boninite, the texture, color and appearance plays an important role in determining the type of rock. Adakite is available in black, brown, light to dark grey colors whereas, Boninite is available in bluish - grey, brown, green, grey colors. Appearance of Adakite is Dull and Soft and that of Boninite is Dull and Soft. Properties of rock is another aspect for Adakite vs Boninite. The hardness of Adakite is 3-4 and that of Boninite is 7. The types of Adakite are Intermediate volcanic rock whereas types of Boninite are Basalt. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Adakite is bluish black while that of Boninite is white. The specific heat capacity of Adakite is 0.84 kJ/Kg K and that of Boninite is 0.84 kJ/Kg K.
