Definition
Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Formation
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Migmatite and Quartzite Properties
Know all about Migmatite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Migmatite and Quartzite belong to Metamorphic Rocks.Texture of Migmatite is Foliated whereas that of Quartzite is Foliated, Granular. Migmatite appears Dull, Banded and Foilated and Quartzite appears Lustrous. The luster of Migmatite is dull to pearly to subvitreous while that of Quartzite is vitreous. Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Migmatite are cemetery markers, jewelry, tombstones, used to manufracture paperweights and bookends and that 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.
