Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
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.

More about Laterite and Pantellerite
Here you can know more about Laterite and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Pantellerite consists of mineral content and compound content. The mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene 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 Laterite vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Laterite is Rough and Banded and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Laterite vs Pantellerite. The hardness of Laterite is 2 and that of Pantellerite is 6-7. The types of Laterite are Laterite 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 Laterite is white while that of Pantellerite is . The specific heat capacity of Laterite is 0.92 kJ/Kg K and that of Pantellerite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Laterite is heat resistant, pressure resistant whereas Pantellerite is heat resistant.
