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'.

Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds

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.

Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.

All about Serpentinite and Coal Properties

Know all about Serpentinite and Coal properties here. All properties of rocks are important as they define the type of rock and its application. Serpentinite belongs to Metamorphic Rocks while Coal belongs to Sedimentary Rocks.Texture of Serpentinite is Earthy whereas that of Coal is Amorphous, Glassy. Serpentinite appears Rough and Dull and Coal appears Veined or Pebbled. The luster of Serpentinite is waxy and dull while that of Coal is dull to vitreous to submetallic. Serpentinite is available in black, brown, green, grey, white colors whereas Coal is available in black, brown, dark brown, grey, light to dark grey colors. The commercial uses of Serpentinite are commemorative tablets, creating artwork and that of Coal are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry.
