Felsite and Serpentinite


Definition

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'.   
Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition

Formation

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.   
Felsite 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 Felsite Properties

Know all about Serpentinite and Felsite properties here. All properties of rocks are important as they define the type of rock and its application. Serpentinite belongs to Metamorphic Rocks while Felsite belongs to Igneous Rocks.Texture of Serpentinite is Earthy whereas that of Felsite is Arborescent Patterned, Vitreous. Serpentinite appears Rough and Dull and Felsite appears Layered, Banded, Veined and Shiny. The luster of Serpentinite is waxy and dull while that of Felsite is vitreous. Serpentinite is available in black, brown, colourless, green, grey, white colors whereas Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. The commercial uses of Serpentinite are commemorative tablets, creating artwork and that of Felsite are mirror, jewelry.
