Definition
Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows
Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock

Formation
Ignimbrites are formed from very poorly sorted mixture of volcanic ash or tuff and pumice lapilli, commonly with scattered lithic fragments.
Sovites are formed due to low degrees of partial melting of rocks.

All about Ignimbrite and Sovite Properties
Know all about Ignimbrite and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Ignimbrite and Sovite belong to Igneous Rocks.Texture of Ignimbrite is Aphanitic whereas that of Sovite is Granular, Poikiloblastic. Ignimbrite appears Dull, Vesicular and Foilated and Sovite appears Dull, Banded and Foilated. The luster of Ignimbrite is vitreous to dull while that of Sovite is subvitreous to dull. Ignimbrite is available in beige, black, brown, grey, pink, white colors whereas Sovite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Ignimbrite are cemetery markers, 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).
