    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.
