Coal also contains minerals, which mostly occur as inorganic crystalline and noncrystalline particles or masses. A coal seam may consist of as much as 50 percent minerals. At more than 50 percent mineral matter, the rock would be termed a carbonaceous shale rather than coal. Most mined coals are less than 20 percent.
