Definition
Argillites are highly compact sedimentary or slightly metamorphosed rocks that consist largely or wholly of particles of clay or silt but lack the fissility of shale or the cleavage characteristic of slate
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

Formation
An argillite is a fine-grained sedimentary rock mainly composed of clay particles which forms from lithified muds which contain variable amounts of silt-sized particles.
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 Argillite and Pantellerite
Here you can know more about Argillite and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Argillite and Pantellerite consists of mineral content and compound content. The mineral content of Argillite includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz 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 Argillite vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Argillite is available in dark grey to black, pink, red, white colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Argillite is Rough and Dull and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Argillite vs Pantellerite. The hardness of Argillite is 2-3 and that of Pantellerite is 6-7. The types of Argillite are Metamorphic rock 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 Argillite is white to grey while that of Pantellerite is . The specific heat capacity of Argillite is 0.87 kJ/Kg K and that of Pantellerite is 0.84 kJ/Kg K.
