Definition
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

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.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Taconite and Conglomerate Properties
Know all about Taconite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Taconite and Conglomerate belong to Sedimentary Rocks.Texture of Taconite is Banded, Trellis whereas that of Conglomerate is Clastic. Taconite appears Layered, Banded, Veined and Shiny and Conglomerate appears Shiny and Rounded. The luster of Taconite is earthy while that of Conglomerate is dull. Taconite is available in red, reddish brown colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Taconite are as a touchstone, cemetery markers, creating artwork and that of Conglomerate are cemetery markers, in aquifers, tombstones.
