Archaeological Significance
Formation
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

All about Itacolumite and Lignite Properties
Know all about Itacolumite and Lignite properties here. All properties of rocks are important as they define the type of rock and its application. Itacolumite and Lignite belong to Sedimentary Rocks.Texture of Itacolumite is Clastic, Granular, Rough whereas that of Lignite is Amorphous, Glassy. Itacolumite appears Rough and Lignite appears Veined or Pebbled. The luster of Itacolumite is dull while that of Lignite is dull to vitreous to submetallic. Itacolumite and Lignite are available in beige, black, brown, 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 Lignite are electricity generation.
