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.
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

All about Diatomite and Arkose Properties
Know all about Diatomite and Arkose properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite and Arkose belong to Sedimentary Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Arkose is Clastic. Diatomite appears Soft and Arkose appears Rough and Dull. The luster of Diatomite and Arkose is dull. Diatomite is available in grey, white, yellow colors whereas Arkose is available in 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 Arkose are in aquifers, soil conditioner, source of magnesia (mgo), tombstones.
