Rapakivi Granite Formation

Rapakivi Granite formation took place millions of years ago. There are a variety of Rapakivi Granite Uses and the Rapakivi Granite 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 Rapakivi Granite is explained below:
