1.1 Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds

5 Formation
5.1 Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
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.
