Definition

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'.

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

Formation

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 is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

All about Serpentinite and Phyllite Properties

Know all about Serpentinite and Phyllite properties here. All properties of rocks are important as they define the type of rock and its application. Serpentinite and Phyllite belong to Metamorphic Rocks.Texture of Serpentinite is Earthy whereas that of Phyllite is Phyllitic Sheen, Slaty. Serpentinite appears Rough and Dull and Phyllite appears Crinkled or Wavy. The luster of Serpentinite is waxy and dull while that of Phyllite is phyllitic. Serpentinite is available in black, brown, green, grey, white colors whereas Phyllite is available in black to grey, light greenish grey colors.
