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'.
Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth

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.
Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

All about Serpentinite and Basalt Properties
Know all about Serpentinite and Basalt properties here. All properties of rocks are important as they define the type of rock and its application. Serpentinite belongs to Metamorphic Rocks while Basalt belongs to Igneous Rocks.Texture of Serpentinite is Earthy whereas that of Basalt is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Serpentinite appears Rough and Dull and Basalt appears Dull and Soft. The luster of Serpentinite is waxy and dull while that of Basalt is . Serpentinite is available in black, brown, green, grey, white colors whereas Basalt is available in black, brown, light to dark grey colors. The commercial uses of Serpentinite are commemorative tablets, creating artwork and that of Basalt are an oil and gas reservoir, commemorative tablets, creating artwork, used in aquariums.
