Archaeological Significance
Formation
Oil Shale forms on the beds of seas and lakes and its formation starts with the organic debris settling and accumulating at the bottom of a lake or sea which are then transformed into rock with the help of high temperature and pressure.
Sovites are formed due to low degrees of partial melting of rocks.

All about Oil shale and Sovite Properties
Know all about Oil shale and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Oil shale belongs to Sedimentary Rocks while Sovite belongs to Igneous Rocks.Texture of Oil shale is Splintery whereas that of Sovite is Granular, Poikiloblastic. Oil shale appears Muddy and Sovite appears Dull, Banded and Foilated. The luster of Oil shale is dull while that of Sovite is subvitreous to dull. Oil shale is available in black, brown, buff, green, grey, red, yellow colors whereas Sovite is available in black, brown, green, grey, pink, white colors. The commercial uses of Oil shale are an oil and gas reservoir 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).
