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.

Porphyry is formed in two stages: the magma cools slowly deep within the crust or the magma is cools rapidly as it erupts from a volcano, creating small grains that are usually invisible to naked eye.

All about Diatomite and Porphyry Properties

Know all about Diatomite and Porphyry properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Porphyry belongs to Igneous Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Porphyry is Porphyritic. Diatomite appears Soft and Porphyry appears Dull. The luster of Diatomite and Porphyry is dull. Diatomite is available in grey, white, yellow colors whereas Porphyry is available in black, brown, colourless, green, grey, red, rust, 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 Porphyry are creating artwork, gemstone, jewelry.
