Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica

Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Taconite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. When the river reaches a lake or sea, its load of transported rocks settles or deposits at the bottom of sea or lake.

All about Quartzite and Taconite Properties
Know all about Quartzite and Taconite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Taconite belongs to Sedimentary Rocks.Texture of Quartzite is Foliated, Granular whereas that of Taconite is Banded, Trellis. Quartzite appears Lustrous and Taconite appears Layered, Banded, Veined and Shiny. The luster of Quartzite is vitreous while that of Taconite is earthy. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Taconite is available in red, reddish brown 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 Taconite are as a touchstone, cemetery markers, creating artwork.
