Formation

Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.  
Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

Serpentinite vs Schist 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 Serpentinite and Schist Reserves. A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.. Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation. 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 Serpentinite vs Schist information and Serpentinite vs Schist characteristics in the upcoming sections.

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

More about Serpentinite and Schist

Here you can know more about Serpentinite and Schist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Schist consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Schist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Schist, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, green, grey, white colors whereas, Schist is available in black, blue, brown, dark brown, green, grey, silver colors. Appearance of Serpentinite is Rough and Dull and that of Schist is Layered and Shiny. Properties of rock is another aspect for Serpentinite vs Schist. The hardness of Serpentinite is 3-5 and that of Schist is 3.5-4. The types of Serpentinite are Jadeitite whereas types of Schist are Mica Schists, Calc-Silicate Schists, Graphite Schists, Blueschists, Whiteschists, Greenschists, Hornblende Schist, Talc Schist, Chlorite Schist, Garnet Schist, Glaucophane schist.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite and Schist is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Schist is 0.70 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Serpentinite is heat resistant whereas Schist is impact resistant, pressure resistant, water resistant.
