Definition
Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks
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
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

More about Phyllite and Boninite
Here you can know more about Phyllite and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Phyllite and Boninite consists of mineral content and compound content. The 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 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 Phyllite vs Boninite, the texture, color and appearance plays an important role in determining the type of rock. Phyllite is available in black to grey, light greenish grey colors whereas, Boninite is available in bluish - grey, brown, colourless, green, grey colors. Appearance of Phyllite is Crinkled or Wavy and that of Boninite is Dull and Soft. Properties of rock is another aspect for Phyllite vs Boninite. The hardness of Phyllite is 1-2 and that of Boninite is 7. The types of Phyllite 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 Phyllite and Boninite is white.
