Definition
Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

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.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

All about Diatomite and Diamictite Properties
Know all about Diatomite and Diamictite properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite and Diamictite belong to Sedimentary Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Diamictite is Clastic. Diatomite appears Soft and Diamictite appears Banded. The luster of Diatomite is dull while that of Diamictite is grainy, pearly and vitreous. Diatomite is available in grey, white, yellow colors whereas Diamictite is available in brown, buff 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 Diamictite are commemorative tablets, creating artwork, production of lime.
