Coals are the most abundant organic-rich sedimentary rock. They consist of undecayed organic matter that either accumulated in place or was transported from elsewhere to the depositional site. The most important organic component in coal is humus. The grade or rank of coal is determined by the percentage of carbon present.

Coal, which is an amorphous form of carbon, is not made of pure carbon. Apart from carbon, it contains complicated organic molecules of decomposed plant and animal material, which have been compressed for millions of years, in the Earth's crust.
