Nepheline Syenite Formation

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

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