Formation
Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
Sovites are formed due to low degrees of partial melting of rocks.

All about Scoria and Sovite Properties
Know all about Scoria and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Scoria and Sovite belong to Igneous Rocks.Texture of Scoria is Vesicular whereas that of Sovite is Granular, Poikiloblastic. Scoria appears Glassy and Vesicular and Sovite appears Dull, Banded and Foilated. The luster of Scoria and Sovite is subvitreous to dull. Scoria is available in black, brown, dark grey to black, red colors whereas Sovite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Scoria are as a traction material on snow-covered roads, creating artwork, high-temperature insulation, in gas barbecue grills 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).
