Formation
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

All about Itacolumite and Granulite Properties
Know all about Itacolumite and Granulite properties here. All properties of rocks are important as they define the type of rock and its application. Itacolumite belongs to Sedimentary Rocks while Granulite belongs to Metamorphic Rocks.Texture of Itacolumite is Clastic, Granular, Rough whereas that of Granulite is Granoblastic. Itacolumite appears Rough and Granulite appears Veined or Pebbled. The luster of Itacolumite is dull while that of Granulite is vitreous. Itacolumite and Granulite are available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow 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 Granulite are curling, gemstone, laboratory bench tops, soil conditioner, tombstones.
