Formation
Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Sovites are formed due to low degrees of partial melting of rocks.

All about Basanite and Sovite Properties
Know all about Basanite and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Basanite and Sovite belong to Igneous Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Sovite is Granular, Poikiloblastic. Basanite appears Glassy or Pearly and Sovite appears Dull, Banded and Foilated. The luster of Basanite is waxy and dull while that of Sovite is subvitreous to dull. Basanite is available in black, brown, green, grey, red, white colors whereas Sovite is available in black, brown, colourless, green, grey, pink, 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 Sovite are an oil and gas reservoir, as a feed additive for livestock, creating artwork, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
