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.

Granophyre is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Diatomite and Granophyre Properties

Know all about Diatomite and Granophyre properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Granophyre belongs to Igneous Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Granophyre is Granophyric. Diatomite appears Soft and Granophyre appears Veined or Pebbled. The luster of Diatomite is dull while that of Granophyre is dull to grainy with sporadic parts pearly and vitreous. Diatomite is available in grey, white, yellow colors whereas Granophyre is available in black, grey, orange, pink, 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 Granophyre are curling, gemstone, laboratory bench tops, tombstones.
