Properties of Coal. There are four broad ranks or types of coal depending upon its age. Commencing with the youngest and lowest carbon content, these are: lignite, subbituminous, bituminous and anthracite. Anthracite is classified as a metamorphic rock because of its subsequent exposure to elevated pressures and temperatures.
