Formation

Formation
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.   
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

All about Itacolumite and Amphibolite Properties

Know all about Itacolumite and Amphibolite properties here. All properties of rocks are important as they define the type of rock and its application. Itacolumite belongs to Sedimentary Rocks while Amphibolite belongs to Metamorphic Rocks.Texture of Itacolumite is Clastic, Granular, Rough whereas that of Amphibolite is Banded, Foliated, Massive. Itacolumite appears Rough and Amphibolite appears Foliated. The luster of Itacolumite is dull while that of Amphibolite is vitreous to dull. Itacolumite and Amphibolite are 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 Itacolumite are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones and that of Amphibolite are cemetery markers, commemorative tablets, creating artwork.
