Features
Easily splits into thin plates, Smooth to touch
Available in lots of colors, Is one of the oldest rock
Archaeological Significance
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.
Mangerite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Schist vs Mangerite 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 Mangerite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Schist and Properties of Mangerite. Learn more about Schist vs Mangerite in the next section. The interior uses of Schist include Decorative aggregates, Floor tiles and Interior decoration whereas the interior uses of Mangerite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Schist and Mangerite, 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 Mangerite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate.
More about Schist and Mangerite
Here you can know more about Schist and Mangerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Schist and Mangerite 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 Mangerite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Schist vs Mangerite, 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, Mangerite is available in black, brown, light to dark grey, white colors. Appearance of Schist is Layered and Shiny and that of Mangerite is Shiny. Properties of rock is another aspect for Schist vs Mangerite. The hardness of Schist is 3.5-4 and that of Mangerite is 6-7. 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 Mangerite are Plutonic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Schist and Mangerite is white. The specific heat capacity of Schist is 0.70 kJ/Kg K and that of Mangerite 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 Mangerite is heat resistant, impact resistant, pressure resistant.
