5 Formation

5.1 Formation

Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

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 Lignite and Diatomite Properties

Know all about Lignite and Diatomite properties here. All properties of rocks are important as they define the type of rock and its application. Lignite and Diatomite belong to Sedimentary Rocks.Texture of Lignite is Amorphous, Glassy whereas that of Diatomite is Clastic or Non-Clastic. Lignite appears Veined or Pebbled and Diatomite appears Soft. The luster of Lignite is dull to vitreous to submetallic while that of Diatomite is dull. Lignite 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 Lignite are electricity generation 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.
