5.1 Formation

Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.

Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.

All about Pyroxenite and Itacolumite Properties

Know all about Pyroxenite and Itacolumite properties here. All properties of rocks are important as they define the type of rock and its application. Pyroxenite belongs to Igneous Rocks while Itacolumite belongs to Sedimentary Rocks.Texture of Pyroxenite is Clastic, Granular, Phaneritic, Porphyritic whereas that of Itacolumite is Clastic, Granular, Rough. Pyroxenite appears Layered, Banded, Veined and Shiny and Itacolumite appears Rough. The luster of Pyroxenite is dull to vitreous to submetallic while that of Itacolumite is dull. Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey 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 Pyroxenite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones and that of Itacolumite are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones.
