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

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