Definition
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.

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.
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

All about Taconite and Ganister Properties
Know all about Taconite and Ganister properties here. All properties of rocks are important as they define the type of rock and its application. Taconite and Ganister belong to Sedimentary Rocks.Texture of Taconite is Banded, Trellis whereas that of Ganister is Clastic, Granular, Rough. Taconite appears Layered, Banded, Veined and Shiny and Ganister appears Rough. The luster of Taconite is earthy while that of Ganister is dull. Taconite is available in red, reddish brown colors whereas Ganister is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. The commercial uses of Taconite are as a touchstone, cemetery markers, creating artwork and that of Ganister are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones.
