Definition
Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

All about Diatomite and Suevite Properties
Know all about Diatomite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Suevite belongs to Metamorphic Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Suevite is Earthy. Diatomite appears Soft and Suevite appears Banded. The luster of Diatomite is dull while that of Suevite is earthy. Diatomite is available in grey, white, yellow colors whereas Suevite is available in black, brown, green, grey, pink 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 Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
