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.

Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds

Etymology

From gan′is-ter i.e a hard, close-grained siliceous stone, often forming the stratum which underlies a coal-seam

From the Old English term col, which has meant mineral of fossilized carbon since the 13th century

Formation

Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.
