Formation
Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.
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.

Shale vs Pantellerite 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. Shale vs Pantellerite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shale and Properties of Pantellerite. Learn more about Shale vs Pantellerite in the next section. The interior uses of Shale include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Pantellerite include Not yet used. Due to some exceptional properties of Shale and Pantellerite, they have various applications in construction industry. The uses of Shale in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Pantellerite include Na.
More about Shale and Pantellerite
Here you can know more about Shale and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shale and Pantellerite consists of mineral content and compound content. The mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides and mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite. You can also check out the list of all Sedimentary Rocks. When we have to compare Shale vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Shale is available in black, brown, buff, green, grey, red, yellow colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Shale is Muddy and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Shale vs Pantellerite. The hardness of Shale is 3 and that of Pantellerite is 6-7. The types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale 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 Shale is white while that of Pantellerite is unknown. The specific heat capacity of Shale is 0.39 kJ/Kg K 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.Shale is heat resistant, impact resistant whereas Pantellerite is heat resistant.
