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.
Jaspillite is an iron rich chemically formed rock which is common in banded iron formation rocks

Formation
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

All about Ganister and Jaspillite Properties
Know all about Ganister and Jaspillite properties here. All properties of rocks are important as they define the type of rock and its application. Ganister and Jaspillite belong to Sedimentary Rocks.Texture of Ganister is Clastic, Granular, Rough whereas that of Jaspillite is Banded, Trellis. Ganister appears Rough and Jaspillite appears Banded and Glassy. The luster of Ganister is dull while that of Jaspillite is earthy. Ganister is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas Jaspillite is available in red, reddish brown 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 Jaspillite are creating artwork, jewelry.
