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.

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.

More about Diatomite and Trachyte

Here you can know more about Diatomite and Trachyte. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Trachyte consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Trachyte includes Augite, Biotite, Feldspar, Hornblade, Plagioclase, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Diatomite vs Trachyte, the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white colors. Appearance of Diatomite is Soft and that of Trachyte is Banded. Properties of rock is another aspect for Diatomite vs Trachyte. The hardness of Diatomite is 1 and that of Trachyte is 6. The types of Diatomite are Diatomite whereas types of Trachyte are Felsic volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diatomite and Trachyte is white. The specific heat capacity of Diatomite is 0.90 kJ/Kg K and that of Trachyte is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Diatomite is heat resistant whereas Trachyte is heat resistant, impact resistant, wear resistant.
