Definition
Mugearite is a type of oligoclase bearing basalt, also comprising of olivine, apatite, and opaque oxides
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Formation
Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Mugearite and Quartzite Properties
Know all about Mugearite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Mugearite belongs to Igneous Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Mugearite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Quartzite is Foliated, Granular. Mugearite appears Dull and Soft and Quartzite appears Lustrous. The luster of Mugearite is not available while that of Quartzite is vitreous. Mugearite is available in black, brown, light to dark grey colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Mugearite are creating artwork 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.
