Formation
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
Sovites are formed due to low degrees of partial melting of rocks.

All about Migmatite and Sovite Properties
Know all about Migmatite and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Migmatite belongs to Metamorphic Rocks while Sovite belongs to Igneous Rocks.Texture of Migmatite is Foliated whereas that of Sovite is Granular, Poikiloblastic. Migmatite appears Dull, Banded and Foilated and Sovite appears Dull, Banded and Foilated. The luster of Migmatite is dull to pearly to subvitreous while that of Sovite is subvitreous to dull. Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors whereas Sovite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Migmatite are cemetery markers, jewelry, tombstones, used to manufracture paperweights and bookends 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).
