All about Conglomerate and Itacolumite Properties
Know all about Conglomerate and Itacolumite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate and Itacolumite belong to Sedimentary Rocks.Texture of Conglomerate is Clastic whereas that of Itacolumite is Clastic, Granular, Rough. Conglomerate appears Shiny and Rounded and Itacolumite appears Rough. The luster of Conglomerate and Itacolumite is dull. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow 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 Conglomerate are cemetery markers, in aquifers, tombstones and that of Itacolumite are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones.
