5.1 Formation

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

Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

Quartzite vs Phyllite 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 Quartzite and Phyllite Reserves. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks. 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 Quartzite vs Phyllite information and Quartzite vs Phyllite characteristics in the upcoming sections.
