Definition
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

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.
Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.

All about Taconite and Carbonatite Properties
Know all about Taconite and Carbonatite properties here. All properties of rocks are important as they define the type of rock and its application. Taconite belongs to Sedimentary Rocks while Carbonatite belongs to Igneous Rocks.Texture of Taconite is Banded, Trellis whereas that of Carbonatite is Granular, Poikiloblastic. Taconite appears Layered, Banded, Veined and Shiny and Carbonatite appears Dull, Banded and Foilated. The luster of Taconite is earthy while that of Carbonatite is subvitreous to dull. Taconite is available in red, reddish brown colors whereas Carbonatite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Taconite are as a touchstone, cemetery markers, creating artwork and that of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux.
