Pressure, temperature, water, time, and some sort of vegetation are the key elements for the formation of coal. According to evolutionary theory, the slow accumulation and decomposition of vegetation living in past ages accounts for the coal seams. However, this theory can not answer why such large amounts of original vegetation without soil can be found in the areas that are now coal seams, or how these coal seams became so thick - some being over two hundred feet in depth.
Scientist Robert Gentry analyzed coalified wood found on the Colorado Plateau in order to determine how long it took for coal to form.1 By treating coal with epoxy and slicing it into thin sheets, Dr. Gentry was able to examine tiny, compressed radiohalos found in the coal. Radiohalos are discolorations in the coal, ejected by radioactive elements in the centers (such as uranium).
According to evolutionary theory, in order for these halos to form, several processes must have occurred. First, water-saturated logs must have been laid down in several different geologic formations, including the Triassic, Jurassic and Eocene layers. Later, uranium solutions infiltrated the water-saturated logs, and uranium decay products were collected at tiny sites within the logs. The radioactive decay from the tiny particles ejected spherical radiation damage regions around those sites, thus producing halos. Finally, a pressure event on the site of the formations compressed the logs as well as the radioactive halos within them. However, because coal is not a malleable substance, scientists know that these logs had not turned to coal at the time the compression event occurred. This points to a quick burial and coalification of the logs – rather than a long time period.
