Formation
Formation
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.
Sovites are formed due to low degrees of partial melting of rocks.

All about Andesite and Sovite Properties
Know all about Andesite and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Andesite and Sovite belong to Igneous Rocks.Texture of Andesite is Aphanitic to Porphyritic whereas that of Sovite is Granular, Poikiloblastic. Andesite appears Dull and Soft and Sovite appears Dull, Banded and Foilated. The luster of Andesite is vitreous while that of Sovite is subvitreous to dull. Andesite is available in bluish - grey, grey, pink, yellow colors whereas Sovite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Andesite are commemorative tablets, creating artwork 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).
