1.1 Definition

Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components

5.1 Formation

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

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

All about Quartzite and Migmatite Properties

Know all about Quartzite and Migmatite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite and Migmatite belong to Metamorphic Rocks.Texture of Quartzite is Foliated, Granular whereas that of Migmatite is Foliated. Quartzite appears Lustrous and Migmatite appears Dull, Banded and Foilated. The luster of Quartzite is vitreous while that of Migmatite is dull to pearly to subvitreous. Quartzite is available in black, blue, brown, green, light grey, purple, 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 Quartzite are an oil and gas reservoir, as armour rock for sea walls, cemetery markers, commemorative tablets, in aquifers, laboratory bench tops, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums and that of Migmatite are cemetery markers, jewelry, tombstones, used to manufracture paperweights and bookends.
