Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.

All about Basanite and Itacolumite Properties
Know all about Basanite and Itacolumite properties here. All properties of rocks are important as they define the type of rock and its application. Basanite belongs to Igneous Rocks while Itacolumite belongs to Sedimentary Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Itacolumite is Clastic, Granular, Rough. Basanite appears Glassy or Pearly and Itacolumite appears Rough. The luster of Basanite is waxy and dull while that of Itacolumite is dull. Basanite is available in black, brown, green, grey, red, white colors whereas Itacolumite is 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 Basanite are as a touchstone, creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms and that of Itacolumite are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones.
