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'.
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions

Etymology
From English word serpentinization.
From the Lherz Massif, an alpine peridotite complex, at Étang de Lers, near Massat in the French Pyrenees; Lherz is the archaic spelling of this location

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.
Lherzolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Serpentinite and Lherzolite Properties
Know all about Serpentinite and Lherzolite properties here. All properties of rocks are important as they define the type of rock and its application. Serpentinite belongs to Metamorphic Rocks while Lherzolite belongs to Igneous Rocks.Texture of Serpentinite is Earthy whereas that of Lherzolite is Grenue. Serpentinite appears Rough and Dull and Lherzolite appears Glassy, Vesicular and Foilated. The luster of Serpentinite is waxy and dull while that of Lherzolite is subvitreous to dull. Serpentinite is available in black, brown, colourless, green, grey, white colors whereas Lherzolite is available in black, dark greenish - grey, green, pink, purple colors. The commercial uses of Serpentinite are commemorative tablets, creating artwork and that of Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums.
