Definition
Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment

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.
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

All about Diatomite and Hyaloclastite Properties
Know all about Diatomite and Hyaloclastite properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Hyaloclastite belongs to Igneous Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Hyaloclastite is Pyroclastic. Diatomite appears Soft and Hyaloclastite appears Dull. The luster of Diatomite is dull while that of Hyaloclastite is dull and grainy. Diatomite is available in grey, white, yellow colors whereas Hyaloclastite is available in brown, grey, yellow 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 Hyaloclastite are cemetery markers, creating artwork.
