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
Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Boninite vs Charnockite 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 Charnockite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Boninite and Properties of Charnockite. Learn more about Boninite vs Charnockite in the next section. The interior uses of Boninite include Decorative aggregates, Homes and Kitchens whereas the interior uses of Charnockite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Boninite and Charnockite, 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 Charnockite include As dimension stone.
More about Boninite and Charnockite
Here you can know more about Boninite and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Boninite and Charnockite consists of mineral content and compound content. The mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite and mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Boninite vs Charnockite, 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, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Boninite is Dull and Soft and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Boninite vs Charnockite. The hardness of Boninite is 7 and that of Charnockite is 6-7. The types of Boninite are Not Available whereas types of Charnockite are Enderbite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Boninite and Charnockite is white.
