Coal, Kentucky Geological Survey, University of Kentucky

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. Many sedimentary rocks are also altered through burial-thermal processes (increasing cementation, etc.).

Why is coal classified as a sedimentary rock? - Quora

Answer Wiki. It was not transformed under temperature and pressure from a pre-existing rock into a metamorphic rock. Coal was lithified by compressive forces from loose material at relatively low temperature. This is most similar to how sedimentary rock is formed, which is generally the compaction and cementation of inorganic material.
