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.
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

Phyllite vs Peridotite 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 Peridotite Reserves. Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. 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 Peridotite information and Phyllite vs Peridotite characteristics in the upcoming sections.

Phyllite vs Peridotite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Phyllite vs Peridotite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Phyllite and Properties of Peridotite. Learn more about Phyllite vs Peridotite in the next section. The interior uses of Phyllite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Peridotite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Phyllite and Peridotite, they have various applications in construction industry. The uses of Phyllite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar, Roadstone and that of Peridotite include As dimension stone, Cobblestones.

More about Phyllite and Peridotite

Here you can know more about Phyllite and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Phyllite and Peridotite consists of mineral content and compound content. The mineral content of Phyllite includes Albite, Alusite, Amphibole, Apatite, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc, Zircon and mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Phyllite vs Peridotite, the texture, color and appearance plays an important role in determining the type of rock. Phyllite is available in black to grey, light greenish grey colors whereas, Peridotite is available in dark greenish - grey colors. Appearance of Phyllite is Crinkled or Wavy and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Phyllite vs Peridotite. The hardness of Phyllite is 1-2 and that of Peridotite is 5.5-6. The types of Phyllite are Not Available whereas types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite.
