Nepheline Syenite vs Variolite

Nepheline Syenite vs Variolite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Nepheline Syenite and Variolite Reserves. Nepheline Syenite is a holocrystalline plutonic rock resembling syenite but containing nepheline and lacking quartz. Variolites are a group of dark green basic igneous rocks which exhibit pale colored spots, or spherules, especially on weathered surfaces, that give them a pockmarked appearance. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes.
