Definition

Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth

Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture

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.

When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.

All about Diatomite and Tonalite Properties

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