5 Formation

5.1 Formation

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

Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.

Phyllite vs Flint 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 Phyllite and Flint Reserves. Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks. Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel. 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 Phyllite vs Flint information and Phyllite vs Flint characteristics in the upcoming sections.
