Pegmatite Formation

Pegmatite formation took place millions of years ago. There are a variety of Pegmatite Uses and the Pegmatite Reserves are found in many countries around the world. The rocks in the earth’s crust continuously undergo changes in their composition which leads to formation of other rocks. Each rock has a unique formation process. Formation of Pegmatite is explained below:

  • Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.
