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.
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Schist vs Syenite 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 Syenite Reserves. Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation. Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals. 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 Syenite information and Schist vs Syenite characteristics in the upcoming sections.

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

More about Schist and Syenite

Here you can know more about Schist and Syenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Schist and Syenite 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 Syenite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Schist vs Syenite, 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, Syenite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Schist is Layered and Shiny and that of Syenite is Banded and Foilated. Properties of rock is another aspect for Schist vs Syenite. The hardness of Schist is 3.5-4 and that of Syenite 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 Syenite are Shonkinite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Schist and Syenite is white. The specific heat capacity of Schist is Not Available and that of Syenite is 0.92 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 Syenite is heat resistant, impact resistant, wear resistant.
