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.COAL TYPES Geologists also classify coal types according to the organic debris, called macerals, from which the coal is formed. Macerals (microscopic organic constituents found in coal) are identified (microscopically) by reflected light the reflective or translucent properties of the coal indicating the individual component macerals.
