  • Is coal a sedimentary or metamorphic rock? 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 burialthermal processes into different ranks Many sedimentary rocks are also altered through burialthermal processesMultiple coal seams can exist in a reserve, with each coal seam separated by sedimentary rock interburden Coal, and the rock above and below the coal seam, is primarily layered sedimentary rock in origin, as opposed to igneous or metamorphic rock The noncoal layers are usually sandstone, limestone, shale, siltstone, and mudstoneCoal Seam an overview | ScienceDirect Topics
