Definition

Argillites are highly compact sedimentary or slightly metamorphosed rocks that consist largely or wholly of particles of clay or silt but lack the fissility of shale or the cleavage characteristic of slate

Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock

Formation

An argillite is a fine-grained sedimentary rock mainly composed of clay particles which forms from lithified muds which contain variable amounts of silt-sized particles.

Sovites are formed due to low degrees of partial melting of rocks.

All about Argillite and Sovite Properties

Know all about Argillite and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Argillite belongs to Sedimentary Rocks while Sovite belongs to Igneous Rocks.Texture of Argillite is Clastic, Polished whereas that of Sovite is Granular, Poikiloblastic. Argillite appears Rough and Dull and Sovite appears Dull, Banded and Foilated. The luster of Argillite is waxy and dull while that of Sovite is subvitreous to dull. Argillite is available in dark grey to black, pink, red, white colors whereas Sovite is available in black, brown, green, grey, pink, white colors. The commercial uses of Argillite are fire resistant, used to manufracture paperweights and bookends 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).
