Archaeological Significance
Formation
Gritstone is a type of sedimentary rock which was formed on the floors of wide river deltas where the grit deposits were laid down, with every tide or flood dumping another layer of sediment.
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.

All about Gritstone and Itacolumite Properties
Know all about Gritstone and Itacolumite properties here. All properties of rocks are important as they define the type of rock and its application. Gritstone and Itacolumite belong to Sedimentary Rocks.Texture of Gritstone is Earthy whereas that of Itacolumite is Clastic, Granular, Rough. Gritstone appears Layered and Foliated and Itacolumite appears Rough. The luster of Gritstone and Itacolumite is dull. Gritstone and Itacolumite 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 Gritstone are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo), tombstones and that of Itacolumite are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones.
