Definition
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

All about Taconite and Suevite Properties
Know all about Taconite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Taconite belongs to Sedimentary Rocks while Suevite belongs to Metamorphic Rocks.Texture of Taconite is Banded, Trellis whereas that of Suevite is Earthy. Taconite appears Layered, Banded, Veined and Shiny and Suevite appears Banded. The luster of Taconite and Suevite is earthy. Taconite is available in red, reddish brown colors whereas Suevite is available in black, brown, green, grey, pink colors. The commercial uses of Taconite are as a touchstone, cemetery markers, creating artwork and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
