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.

All about Gritstone and Pantellerite Properties
Know all about Gritstone and Pantellerite properties here. All properties of rocks are important as they define the type of rock and its application. Gritstone belongs to Sedimentary Rocks while Pantellerite belongs to Igneous Rocks.Texture of Gritstone is Earthy whereas that of Pantellerite is Eutaxitic. Gritstone appears Layered and Foliated and Pantellerite appears Layered and Foliated. The luster of Gritstone is dull while that of Pantellerite is earthy. 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. The commercial uses of Gritstone are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo), tombstones and that of Pantellerite are creating artwork.
