Formation

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.   
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

All about Oil shale and Evaporite Properties

Know all about Oil shale and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Oil shale and Evaporite belong to Sedimentary Rocks.Texture of Oil shale is Splintery whereas that of Evaporite is Earthy. Oil shale appears Muddy and Evaporite appears Glassy, Vesicular and Foilated. The luster of Oil shale is dull while that of Evaporite is subvitreous to dull. Oil shale is available in black, brown, buff, green, grey, red, yellow colors whereas Evaporite is available in colourless, green, grey, silver, white colors. The commercial uses of Oil shale are an oil and gas reservoir and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
