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
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Boninite vs Dolomite 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 Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Boninite and Properties of Dolomite. Learn more about Boninite vs Dolomite in the next section. The interior uses of Boninite include Decorative aggregates, Homes and Kitchens whereas the interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Boninite and Dolomite, 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 Dolomite 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, Production of glass and ceramics, Serves as an oil and gas reservoir rock.
More about Boninite and Dolomite
Here you can know more about Boninite and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Boninite and Dolomite consists of mineral content and compound content. The mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite and mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Boninite vs Dolomite, 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, Dolomite is available in black, brown, colourless, green, grey, pink, white colors.
