5 Formation
5.1 Formation
Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.
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.

Schist 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 Schist and Peridotite Reserves. Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation. 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 Schist vs Peridotite information and Schist vs Peridotite characteristics in the upcoming sections.

Schist 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. Schist vs Peridotite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Schist and Properties of Peridotite. Learn more about Schist vs Peridotite in the next section. The interior uses of Schist include Decorative aggregates, Floor tiles and Interior decoration whereas the interior uses of Peridotite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Schist and Peridotite, they have various applications in construction industry. The uses of Schist in construction industry include As dimension stone, Building houses or walls, Cement manufacture, For road aggregate, Roadstone and that of Peridotite include As dimension stone, Cobblestones.

More about Schist and Peridotite

Here you can know more about Schist and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Schist and Peridotite consists of mineral content and compound content. The mineral content of Schist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc 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 Schist vs Peridotite, the texture, color and appearance plays an important role in determining the type of rock. Schist is available in black, blue, brown, dark brown, green, grey, silver colors whereas, Peridotite is available in dark greenish - grey colors. Appearance of Schist is Layered and Shiny and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Schist vs Peridotite. The hardness of Schist is 3.5-4 and that of Peridotite is 5.5-6. The types of Schist are Mica Schists, Calc-Silicate Schists, Graphite Schists, Blueschists, Whiteschists, Greenschists, Hornblende Schist, Talc Schist, Chlorite Schist, Garnet Schist, Glaucophane schist. whereas types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Schist and Peridotite is white. The specific heat capacity of Schist is Not Available and that of Peridotite is 1.26 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Schist is impact resistant, pressure resistant, water resistant whereas Peridotite is heat resistant, pressure resistant, wear resistant.
