Formation
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
Kenyte 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 Kenyte Properties
Know all about Itacolumite and Kenyte properties here. All properties of rocks are important as they define the type of rock and its application. Itacolumite belongs to Sedimentary Rocks while Kenyte belongs to Igneous Rocks.Texture of Itacolumite is Clastic, Granular, Rough whereas that of Kenyte is Glassy, Granular. Itacolumite appears Rough and Kenyte appears Banded and Foilated. The luster of Itacolumite is dull while that of Kenyte is greasy to dull. 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 Kenyte is available in brown, buff, cream, green, grey, pink, white 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 Kenyte are cemetery markers, creating artwork.
