Coal is the remains of carbon based material (once living plants). It was likely made by huge mats of vegetation that were ripped up from their roots in violent storms and piled in layers during or after the great flood of Noah's day. Sediment was deposited on top of these layers and this in turn squeezed out the water. The temperature of the buried flora then was increased possibly as a result of burial by cooling volcanic lava and ash. Then the plants began to char which turned it into coal. This concept is supported by the natural occurrences during and after the Mt. St. Helens eruption in 1980. Whether coal, oil, concretion or carbon films are found as a result of plant life being buried may have more to do with the density of the plant life, the amount of sediment under where it was buried and the heat that was particular to the area in question caused by rapidly cooling rocks from volcanic activity and/or accelerated nuclear decay within some types of flows from this volcanic activity.
