Phonolite Formation

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

Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
