Charnockite 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 Charnockite and Pegmatite Reserves. Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar. 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 Charnockite vs Pegmatite information and Charnockite vs Pegmatite characteristics in the upcoming sections.

Charnockite vs Pegmatite Characteristics
