Archaeological Significance
Formation
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.
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 Diatomite and Taconite Properties
Know all about Diatomite and Taconite properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite and Taconite belong to Sedimentary Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Taconite is Banded, Trellis. Diatomite appears Soft and Taconite appears Layered, Banded, Veined and Shiny. The luster of Diatomite is dull while that of Taconite is earthy. Diatomite is available in grey, white, yellow colors whereas Taconite is available in red, reddish brown colors. The commercial uses 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 and that of Taconite are as a touchstone, cemetery markers, creating artwork.
