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.
Comendite is a type of Igneous rock which is formed due to cooling and solidification of lava or magma. It may form with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Lignite vs Comendite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Lignite and Comendite Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. Comendite is a hard, peralkaline igneous rock, a type of light blue grey rhyolite. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Lignite vs Comendite information and Lignite vs Comendite characteristics in the upcoming sections.
