Definition

A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

Oil Shale is a fine-grained sedimentary rock from which oil is extracted

Formation

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

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 Serpentinite and Oil shale Properties

Know all about Serpentinite and Oil shale properties here. All properties of rocks are important as they define the type of rock and its application. Serpentinite belongs to Metamorphic Rocks while Oil shale belongs to Sedimentary Rocks.Texture of Serpentinite is Earthy whereas that of Oil shale is Splintery. Serpentinite appears Rough and Dull and Oil shale appears Muddy. The luster of Serpentinite is waxy and dull while that of Oil shale is dull. Serpentinite is available in black, brown, green, grey, white colors whereas Oil shale is available in black, brown, buff, green, grey, red, yellow colors. The commercial uses of Serpentinite are commemorative tablets, creating artwork and that of Oil shale are an oil and gas reservoir.
