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'.

Granulite is fine to medium grained metamorphic rock with a granular of polygonal 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.

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

All about Serpentinite and Granulite Properties

Know all about Serpentinite and Granulite properties here. All properties of rocks are important as they define the type of rock and its application. Serpentinite and Granulite belong to Metamorphic Rocks.Texture of Serpentinite is Earthy whereas that of Granulite is Granoblastic. Serpentinite appears Rough and Dull and Granulite appears Veined or Pebbled. The luster of Serpentinite is waxy and dull while that of Granulite is vitreous. Serpentinite and Granulite are available in black, brown, green, grey, white colors. The commercial uses of Serpentinite are commemorative tablets, creating artwork and that of Granulite are curling, gemstone, laboratory bench tops, soil conditioner, tombstones.
