Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
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
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

All about Basanite and Ganister Properties
Know all about Basanite and Ganister properties here. All properties of rocks are important as they define the type of rock and its application. Basanite belongs to Igneous Rocks while Ganister belongs to Sedimentary Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Ganister is Clastic, Granular, Rough. Basanite appears Glassy or Pearly and Ganister appears Rough. The luster of Basanite is waxy and dull while that of Ganister is dull. Basanite is available in black, brown, green, grey, red, 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 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 Ganister are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones.
