Definition
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs
Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock

Formation
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.
Sovites are formed due to low degrees of partial melting of rocks.

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