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
Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

Boninite vs Phyllite 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 Phyllite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Boninite and Properties of Phyllite. Learn more about Boninite vs Phyllite in the next section. The interior uses of Boninite include Decorative aggregates, Homes and Kitchens whereas the interior uses of Phyllite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Boninite and Phyllite, they have various applications in construction industry.

More about Boninite and Phyllite
Here you can know more about Boninite and Phyllite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Boninite and Phyllite consists of mineral content and compound content. The mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite and mineral content of Phyllite includes Albite, Alusite, Amphibole, Apatite, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Boninite vs Phyllite, 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, Phyllite is available in black to grey, light greenish grey colors. Appearance of Boninite is Dull and Soft and that of Phyllite is Crinkled or Wavy. Properties of rock is another aspect for Boninite vs Phyllite. The hardness of Boninite is 7 and that of Phyllite is 1-2. The types of Boninite are Not Available whereas types of Phyllite are Not Available.
