Definition
Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar
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
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
