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.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

Phyllite vs Scoria 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 Scoria Reserves. Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. 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 Scoria information and Phyllite vs Scoria characteristics in the upcoming sections.

Phyllite vs Scoria Characteristics
