Formation

Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.

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.

All about Trachyte and Diatomite Properties

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