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.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.

All about Diatomite and Gabbro Properties
Know all about Diatomite and Gabbro properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Gabbro belongs to Igneous Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Gabbro is Phaneritic. Diatomite appears Soft and Gabbro appears Veined and Shiny. The luster of Diatomite is dull while that of Gabbro is not available. Diatomite is available in grey, white, yellow colors whereas Gabbro is available in dark grey to black 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 Gabbro are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
