Why is coal not metamorphic rock?
Because coal undergoes physical and chemical changes as a result of increased heat there is sometimes a misconception that coal is a metamorphic rock. Coal is a sedimentary rock. Coal is altered through biological and burial-thermal processes into different ranks.
Why coal is sedimentary rock?
Being composed of carbon coal forms a carbonaceous deposit. Having been transported and accumulated in a single deposit it is sedimentary. Having undergone metamorphosis and petrification it is a rock. Consequently it is reasonable to classify coal as a carbonaceous sedimentary rock.
