Pegmatite vs Lignite

Pegmatite vs Lignite 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 Pegmatite and Lignite Reserves. Pegmatite rock is a holocrystalline, intrusive igneous rock which is composed of interlocking phaneritic crystals. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. 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.
