Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
  
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.

All about Basanite and Diatomite Properties
Know all about Basanite and Diatomite properties here. All properties of rocks are important as they define the type of rock and its application. Basanite belongs to Igneous Rocks while Diatomite belongs to Sedimentary Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Diatomite is Clastic or Non-Clastic. Basanite appears Glassy or Pearly and Diatomite appears Soft. The luster of Basanite is waxy and dull while that of Diatomite is dull. Basanite is available in black, brown, green, grey, red, white colors whereas Diatomite is available in grey, white, yellow colors. The commercial uses of Basanite are as a touchstone, creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms and that 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.
