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.
Pantellerite 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.

The uses of Schist in construction industry include As dimension stone, Building houses or walls, Cement manufacture, For road aggregate, Roadstone and that of Pantellerite include Na.
More about Schist and Pantellerite
Here you can know more about Schist and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Schist and Pantellerite 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 Pantellerite includes Amphibole, Feldspar, Ilmenite. You can also check out the list of all Metamorphic Rocks. When we have to compare Schist vs Pantellerite, 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, Pantellerite is available in dark greenish - grey colors. Appearance of Schist is Layered and Shiny and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Schist vs Pantellerite. The hardness of Schist is 3.5-4 and that of Pantellerite 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 Pantellerite are Pantelleritic Ignimbrite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Schist is white while that of Pantellerite is unknown. The specific heat capacity of Schist is Not Available and that of Pantellerite is Not Available. 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 Pantellerite is heat resistant.
