Ganister and Pegmatite

1 Definition
1.1 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.
Pegmatite rock is a holocrystalline, intrusive igneous rock which is composed of interlocking phaneritic crystals

5 Formation
5.1 Formation
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.

All about Ganister and Pegmatite Properties

Know all about Ganister and Pegmatite properties here. All properties of rocks are important as they define the type of rock and its application. Ganister belongs to Sedimentary Rocks while Pegmatite belongs to Igneous Rocks.Texture of Ganister is Clastic, Granular, Rough whereas that of Pegmatite is Pegmatitic. Ganister appears Rough and Pegmatite appears Layered, Banded, Veined and Shiny. The luster of Ganister is dull while that of Pegmatite is grainy, pearly and vitreous. 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 Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, 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 Pegmatite are creating artwork, jewelry, source of corundum, tourmalines, beryls and topaz.
