Archaeological Significance
Formation
Sovites are formed due to low degrees of partial melting of rocks.
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.

All about Sovite and Dacite Properties
Know all about Sovite and Dacite properties here. All properties of rocks are important as they define the type of rock and its application. Sovite and Dacite belong to Igneous Rocks.Texture of Sovite is Granular, Poikiloblastic whereas that of Dacite is Aphanitic to Porphyritic. Sovite appears Dull, Banded and Foilated and Dacite appears Vesicular. The luster of Sovite and Dacite is subvitreous to dull. Sovite is available in black, brown, green, grey, pink, white colors whereas Dacite is available in bluish - grey, brown, grey, light to dark grey colors. The commercial uses 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) and that of Dacite are commemorative tablets, creating artwork.
