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'.

Trachyte is a grey fine-grained volcanic rock which mainly consists of alkali feldspar

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.

Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.

All about Serpentinite and Trachyte Properties

Know all about Serpentinite and Trachyte properties here. All properties of rocks are important as they define the type of rock and its application. Serpentinite belongs to Metamorphic Rocks while Trachyte belongs to Igneous Rocks.Texture of Serpentinite is Earthy whereas that of Trachyte is Aphanitic to Porphyritic. Serpentinite appears Rough and Dull and Trachyte appears Banded. The luster of Serpentinite is waxy and dull while that of Trachyte is metallic. Serpentinite is available in black, brown, green, grey, white colors whereas Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white colors. The commercial uses of Serpentinite are commemorative tablets, creating artwork and that of Trachyte are cemetery markers, creating artwork.
