Definition
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas
  
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
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
  
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

All about Laterite and Ganister Properties
Know all about Laterite and Ganister properties here. All properties of rocks are important as they define the type of rock and its application. Laterite and Ganister belong to Sedimentary Rocks.Texture of Laterite is Earthy, Massive, Porphyritic whereas that of Ganister is Clastic, Granular, Rough. Laterite appears Rough and Banded and Ganister appears Rough. The luster of Laterite and Ganister is dull. Laterite is available in brown, buff, red 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 Laterite are an oil and gas reservoir, source of bauxite, used in aquariums and that of Ganister are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones.
