Definition
Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.
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
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

Granulite 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. Granulite vs Boninite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Boninite. Learn more about Granulite vs Boninite in the next section. The interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Boninite include Decorative aggregates, Homes and Kitchens. Due to some exceptional properties of Granulite and Boninite, they have various applications in construction industry. The uses of Granulite in construction industry include As dimension stone, Building houses or walls 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 Granulite and Boninite
Here you can know more about Granulite and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Boninite consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Boninite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Boninite is available in bluish - grey, brown, colourless, green, grey colors. Appearance of Granulite is Veined or Pebbled and that of Boninite is Dull and Soft. Properties of rock is another aspect for Granulite vs Boninite. The hardness of Granulite is 6-7 and that of Boninite is 7. The types of Granulite are Not Available whereas types of Boninite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Boninite is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Boninite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granulite is heat resistant, wear resistant whereas Boninite is heat resistant, impact resistant, pressure resistant, wear resistant.
