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

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