Definition
Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite
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.

Formation
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

All about Granodiorite and Ganister Properties
Know all about Granodiorite and Ganister properties here. All properties of rocks are important as they define the type of rock and its application. Granodiorite belongs to Igneous Rocks while Ganister belongs to Sedimentary Rocks.Texture of Granodiorite is Granular, Phaneritic whereas that of Ganister is Clastic, Granular, Rough. Granodiorite appears Veined or Pebbled and Ganister appears Rough. The luster of Granodiorite is grainy, pearly and vitreous while that of Ganister is dull. Granodiorite is available in black, grey, orange, pink, white colors whereas Ganister is 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 Granodiorite are curling, gemstone, laboratory bench tops, tombstones and that of Ganister are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones.
