Definition
Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities
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

Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

Scoria 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. Scoria vs Boninite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Scoria and Properties of Boninite. Learn more about Scoria vs Boninite in the next section. The interior uses of Scoria include Decorative aggregates and Interior decoration whereas the interior uses of Boninite include Decorative aggregates, Homes and Kitchens. Due to some exceptional properties of Scoria and Boninite, they have various applications in construction industry. The uses of Scoria in construction industry include Cement manufacture, Construction aggregate, For road aggregate, In landscaping and drainage works 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 Scoria and Boninite
Here you can know more about Scoria and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Boninite consists of mineral content and compound content. The mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica 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 Scoria vs Boninite, the texture, color and appearance plays an important role in determining the type of rock. Scoria is available in black, brown, dark grey to black, red colors whereas, Boninite is available in bluish - grey, brown, green, grey colors. Appearance of Scoria is Glassy and Vesicular and that of Boninite is Dull and Soft. Properties of rock is another aspect for Scoria vs Boninite. The hardness of Scoria is 5-6 and that of Boninite is 7. The types of Scoria are Basaltic Scoria and Andesitic Scoria 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 Scoria and Boninite is white.
