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.

Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

All about Oil shale and Peridotite Properties

Know all about Oil shale and Peridotite 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 Peridotite belongs to Igneous Rocks.Texture of Oil shale is Splintery whereas that of Peridotite is Phaneritic. Oil shale appears Muddy and Peridotite appears Rough and Shiny. The luster of Oil shale is dull while that of Peridotite is shiny. Oil shale is available in black, brown, buff, green, grey, red, yellow colors whereas Peridotite is available in dark greenish - grey colors. The commercial uses of Oil shale are an oil and gas reservoir and that of Peridotite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds.
