Definition
Harzburgite is a plutonic rock of the peridotite group consisting largely of orthopyroxene and olivine
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
Harzburgite 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.
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 Harzburgite and Serpentinite Properties
Know all about Harzburgite and Serpentinite properties here. All properties of rocks are important as they define the type of rock and its application. Harzburgite belongs to Igneous Rocks while Serpentinite belongs to Metamorphic Rocks.Texture of Harzburgite is Phaneritic whereas that of Serpentinite is Earthy. Harzburgite appears Rough and Shiny and Serpentinite appears Rough and Dull. The luster of Harzburgite is shiny while that of Serpentinite is waxy and dull. Harzburgite is available in dark greenish - grey colors whereas Serpentinite is available in black, brown, colourless, green, grey, white colors. The commercial uses of Harzburgite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds and that of Serpentinite are commemorative tablets, creating artwork.
