Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
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
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
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 Basanite and Serpentinite Properties
Know all about Basanite and Serpentinite properties here. All properties of rocks are important as they define the type of rock and its application. Basanite belongs to Igneous Rocks while Serpentinite belongs to Metamorphic Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Serpentinite is Earthy. Basanite appears Glassy or Pearly and Serpentinite appears Rough and Dull. The luster of Basanite and Serpentinite is waxy and dull. Basanite is available in black, brown, green, grey, red, white colors whereas Serpentinite is available in black, brown, colourless, green, grey, white colors. The commercial uses of Basanite are as a touchstone, creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms and that of Serpentinite are commemorative tablets, creating artwork.
