Scoria vs Pegmatite 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 Scoria and Pegmatite Reserves. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. Pegmatite rock is a holocrystalline, intrusive igneous rock which is composed of interlocking phaneritic crystals. 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 Scoria vs Pegmatite information and Scoria vs Pegmatite characteristics in the upcoming sections.
