5 Formation

5.1 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.

Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

All about Diatomite and Phyllite Properties

Know all about Diatomite and Phyllite properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Phyllite belongs to Metamorphic Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Phyllite is Phyllitic Sheen, Slaty. Diatomite appears Soft and Phyllite appears Crinkled or Wavy. The luster of Diatomite is dull while that of Phyllite is phyllitic. Diatomite is available in grey, white, yellow colors whereas Phyllite is available in black to grey, light greenish grey 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 Phyllite are cemetery markers, commemorative tablets, creating artwork, writing slates.
