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'.
Pegmatite rock is a holocrystalline, intrusive igneous rock which is composed of interlocking phaneritic crystals

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.
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.

All about Serpentinite and Pegmatite Properties
Know all about Serpentinite and Pegmatite properties here. All properties of rocks are important as they define the type of rock and its application. Serpentinite belongs to Metamorphic Rocks while Pegmatite belongs to Igneous Rocks.Texture of Serpentinite is Earthy whereas that of Pegmatite is Pegmatitic. Serpentinite appears Rough and Dull and Pegmatite appears Layered, Banded, Veined and Shiny. The luster of Serpentinite is waxy and dull while that of Pegmatite is grainy, pearly and vitreous. Serpentinite is available in black, brown, colourless, green, grey, white colors whereas Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors. The commercial uses of Serpentinite are commemorative tablets, creating artwork and that of Pegmatite are creating artwork, jewelry, source of corundum, tourmalines, beryls and topaz.
