Definition

Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica

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

Formation

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.

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