Definition
Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.
Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock

Formation
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.
Sovites are formed due to low degrees of partial melting of rocks.

All about Gossan and Sovite Properties
Know all about Gossan and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Gossan belongs to Metamorphic Rocks while Sovite belongs to Igneous Rocks.Texture of Gossan is Rough, Sandy whereas that of Sovite is Granular, Poikiloblastic. Gossan appears Dull and Banded and Sovite appears Dull, Banded and Foilated. The luster of Gossan is metallic while that of Sovite is subvitreous to dull. Gossan is available in brown, brown- black, gold, green, rust colors whereas Sovite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Gossan are cemetery markers, commemorative tablets, gemstone 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).
