Definition
Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks
Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock

Archaeological Significance
Formation
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.
Sovites are formed due to low degrees of partial melting of rocks.

All about Phyllite and Sovite Properties
Know all about Phyllite and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Phyllite belongs to Metamorphic Rocks while Sovite belongs to Igneous Rocks.Texture of Phyllite is Phyllitic Sheen, Slaty whereas that of Sovite is Granular, Poikiloblastic. Phyllite appears Crinkled or Wavy and Sovite appears Dull, Banded and Foilated. The luster of Phyllite is phyllitic while that of Sovite is subvitreous to dull. Phyllite is available in black to grey, light greenish grey colors whereas Sovite is available in black, brown, green, grey, pink, white colors. The commercial uses of Phyllite are cemetery markers, commemorative tablets, creating artwork, writing slates 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).
