5 Formation

5.1 Formation

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.

Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.

All about Coal and Diatomite Properties

Know all about Coal and Diatomite properties here. All properties of rocks are important as they define the type of rock and its application. Coal and Diatomite belong to Sedimentary Rocks.Texture of Coal is Amorphous, Glassy whereas that of Diatomite is Clastic or Non-Clastic. Coal appears Veined or Pebbled and Diatomite appears Soft. The luster of Coal is dull to vitreous to submetallic while that of Diatomite is dull. Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas Diatomite is available in grey, white, yellow colors. The commercial uses of Coal are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry and that of Diatomite are alumina refineries, animal feed filler, as a feed additive for livestock, creating artwork, drawing on blackboards, fire resistant, gymnasts, athletes and mountain climbers use for grip, in aquifers, soil conditioner, to ignite fire, used as a filter medium, used as an insecticide, whiting material in toothpaste, paint and paper.
