Formation

Formation
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.   
Pyrolite 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 Itacolumite and Pyrolite Properties

Know all about Itacolumite and Pyrolite properties here. All properties of rocks are important as they define the type of rock and its application. Itacolumite belongs to Sedimentary Rocks while Pyrolite belongs to Igneous Rocks.Texture of Itacolumite is Clastic, Granular, Rough whereas that of Pyrolite is Phaneritic. Itacolumite appears Rough and Pyrolite appears Rough and Shiny. The luster of Itacolumite is dull while that of Pyrolite is shiny. Itacolumite is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas Pyrolite is available in dark greenish - grey colors. The commercial uses of Itacolumite are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones and that of Pyrolite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds.
