Formation
Gritstone is a type of sedimentary rock which was formed on the floors of wide river deltas where the grit deposits were laid down, with every tide or flood dumping another layer of sediment.
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 Gritstone and Pantellerite
Here you can know more about Gritstone and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gritstone and Pantellerite consists of mineral content and compound content. The mineral content of Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, 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 Gritstone vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Gritstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Gritstone is Layered and Foliated and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Gritstone vs Pantellerite. Hardness of Gritstone and Pantellerite is 6-7. The types of Gritstone are Not Available 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 Gritstone is white while that of Pantellerite is unknown. The specific heat capacity of Gritstone is 0.92 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.Gritstone is heat resistant, impact resistant, pressure resistant whereas Pantellerite is heat resistant.
