Definition
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.
Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth

Formation
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
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 Ganister and Diatomite Properties
Know all about Ganister and Diatomite properties here. All properties of rocks are important as they define the type of rock and its application. Ganister and Diatomite belong to Sedimentary Rocks.Texture of Ganister is Clastic, Granular, Rough whereas that of Diatomite is Clastic or Non-Clastic. Ganister appears Rough and Diatomite appears Soft. The luster of Ganister and Diatomite is dull. Ganister and Diatomite are available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. The commercial uses of Ganister are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones 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.
