Formation
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
Wehrlite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Itacolumite and Wehrlite Properties
Know all about Itacolumite and Wehrlite properties here. All properties of rocks are important as they define the type of rock and its application. Itacolumite belongs to Sedimentary Rocks while Wehrlite belongs to Igneous Rocks.Texture of Itacolumite is Clastic, Granular, Rough whereas that of Wehrlite is Banded. Itacolumite appears Rough and Wehrlite appears Rough and Banded. The luster of Itacolumite is dull while that of Wehrlite is metallic. Itacolumite is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas Wehrlite is available in dark greenish - grey, green 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 Wehrlite are cemetery markers, creating artwork, gemstone, jewelry.
