Archaeological Significance
Formation
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.
Sovites are formed due to low degrees of partial melting of rocks.

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