A third phase in this coal development is bituminous (soft coal) which is one of the two stages used as a fuel in generating electrical power. The fourth and final phase results in the formation of anthracite (hard coal). If anthracite coal was placed under more heat and pressure, it would eventually be compressed into a diamond.

Coal is a solid, black, readily combustible fossil fuel that contains a large amount of carbon-based material - approximately 50% of its weight. The formation of coal takes a significant amount of time (on the order of a few million years), and the first coal-bearing rock units appeared about 290-360 million years ago, at a time known as the Carboniferous or "coal-bearing" Period.
