5.1 Formation

Epidosite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

Epidosite vs Quartzite 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 Epidosite and Quartzite Reserves. Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. 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. You can check out Epidosite vs Quartzite information and Epidosite vs Quartzite characteristics in the upcoming sections.
