Definition
Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

Formation
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Phyllite vs Serpentinite 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. Phyllite vs Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Phyllite and Properties of Serpentinite. Learn more about Phyllite vs Serpentinite in the next section. The interior uses of Phyllite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Phyllite and Serpentinite, they have various applications in construction industry. The uses of Phyllite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar, Roadstone and that of Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Phyllite and Serpentinite
Here you can know more about Phyllite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Phyllite and Serpentinite 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 Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Phyllite vs Serpentinite, 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, Serpentinite is available in black, brown, colourless, green, grey, white colors. Appearance of Phyllite is Crinkled or Wavy and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Phyllite vs Serpentinite. The hardness of Phyllite is 1-2 and that of Serpentinite is 3-5. The types of Phyllite are Not Available whereas types of Serpentinite are Jadeitite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Phyllite is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Phyllite is Not Available and that of Serpentinite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Phyllite is heat resistant, pressure resistant, water resistant whereas Serpentinite is heat resistant.
