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.

Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.

Lignite vs Gabbro 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 Gabbro Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt. 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 Gabbro information and Lignite vs Gabbro characteristics in the upcoming sections.
