Porphyry is formed in two stages: the magma cools slowly deep within the crust or the magma is cools rapidly as it erupts from a volcano, creating small grains that are usually invisible to naked eye. 0

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