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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

Schist vs Turbidite 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 Turbidite Reserves. Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation. A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles. 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 Turbidite information and Schist vs Turbidite characteristics in the upcoming sections.

Schist vs Turbidite 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 Turbidite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Schist and Properties of Turbidite. Learn more about Schist vs Turbidite in the next section. The interior uses of Schist include Decorative aggregates, Floor tiles and Interior decoration whereas the interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Schist and Turbidite, 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 Turbidite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement.

More about Schist and Turbidite

Here you can know more about Schist and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Schist and Turbidite 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 Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Metamorphic Rocks. When we have to compare Schist vs Turbidite, 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, Turbidite is available in black, brown, colourless, green, grey, pink colors. Appearance of Schist is Layered and Shiny and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Schist vs Turbidite. The hardness of Schist is 3.5-4 and that of Turbidite is 3.
