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.

Graywacke rock is a type of sedimentary rock, which is also known as immature sandstone, which is indurated, dark grey and consisting of poorly sorted angular to sub-angular, sand-sized grains.

Lignite vs Greywacke 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 Greywacke Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. Greywacke is defined as a dark coarse-grained sandstone rock which contains more than 15 per cent clay. 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 Greywacke information and Lignite vs Greywacke characteristics in the upcoming sections.
