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'.
Very fine grained fault rock which is composed of glassy matrix that often contains inclusions of wall-rock fragments.

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.

All about Serpentinite and Pseudotachylite Properties
Know all about Serpentinite and Pseudotachylite properties here. All properties of rocks are important as they define the type of rock and its application. Serpentinite and Pseudotachylite belong to Metamorphic Rocks.Texture of Serpentinite is Earthy whereas that of Pseudotachylite is Quench. Serpentinite appears Rough and Dull and Pseudotachylite appears Dull and Soft. The luster of Serpentinite is waxy and dull while that of Pseudotachylite is vitreous. Serpentinite is available in black, brown, green, grey, white colors whereas Pseudotachylite is available in black, brown, green, grey, pink, white colors. The commercial uses of Serpentinite are commemorative tablets, creating artwork and that of Pseudotachylite are creating artwork, gemstone.
