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.
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

Formation
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
