Trondhjemite Formation

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