Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth

Archaeological Significance
Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
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 Conglomerate and Diatomite Properties
Know all about Conglomerate and Diatomite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate and Diatomite belong to Sedimentary Rocks.Texture of Conglomerate is Clastic whereas that of Diatomite is Clastic or Non-Clastic. Conglomerate appears Shiny and Rounded and Diatomite appears Soft. The luster of Conglomerate and Diatomite is dull. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Diatomite is available in grey, white, yellow colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones 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.
