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.

Trachyte vs Diatomite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Trachyte vs Diatomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Trachyte and Properties of Diatomite. Learn more about Trachyte vs Diatomite in the next section. The interior uses of Trachyte include Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Diatomite include Decorative aggregates, Homes and Interior decoration.
