5.1 Formation

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

Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

All about Itacolumite and Migmatite Properties

Know all about Itacolumite and Migmatite properties here. All properties of rocks are important as they define the type of rock and its application. Itacolumite belongs to Sedimentary Rocks while Migmatite belongs to Metamorphic Rocks.Texture of Itacolumite is Clastic, Granular, Rough whereas that of Migmatite is Foliated. Itacolumite appears Rough and Migmatite appears Dull, Banded and Foilated. The luster of Itacolumite is dull while that of Migmatite is dull to pearly to subvitreous. 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 Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black 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 Migmatite are cemetery markers, jewelry, tombstones, used to manufracture paperweights and bookends.
