Definition
Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites

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.
Wehrlite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Diatomite and Wehrlite Properties
Know all about Diatomite and Wehrlite properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Wehrlite belongs to Igneous Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Wehrlite is Banded. Diatomite appears Soft and Wehrlite appears Rough and Banded. The luster of Diatomite is dull while that of Wehrlite is metallic. Diatomite is available in grey, white, yellow colors whereas Wehrlite is available in dark greenish - grey, green 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 Wehrlite are cemetery markers, creating artwork, gemstone, jewelry.
