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.
  
Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.

All about Taconite and Diatomite Properties
Know all about Taconite and Diatomite properties here. All properties of rocks are important as they define the type of rock and its application. Taconite and Diatomite belong to Sedimentary Rocks.Texture of Taconite is Banded, Trellis whereas that of Diatomite is Clastic or Non-Clastic. Taconite appears Layered, Banded, Veined and Shiny and Diatomite appears Soft. The luster of Taconite is earthy while that of Diatomite is dull. Taconite is available in red, reddish brown colors whereas Diatomite is available in grey, white, yellow colors. The commercial uses of Taconite are as a touchstone, cemetery markers, creating artwork and that of Diatomite are alumina refineries, animal feed filler, as a feed additive for livestock, creating artwork, drawing on blackboards, fire resistant, gymnasts, athletes and mountain climbers use for grip, in aquifers, soil conditioner, to ignite fire, used as a filter medium, used as an insecticide, whiting material in toothpaste, paint and paper.
