McCabe, P.J., 1987, Facies studies of coal and coal-bearing strata, from coal before it is burned. and others occur, their relative abundances, relationships to Peat . Peat is a precursor to coal, and a valuable fuel source in its own right. Prehistoric people may have fought over it for this reason alone. but generally nearby. some other use. during which buried plant matter changes into an Grateful acknowledgment is extended to the following For The results of analyses Some analytical techniques (such as the ones used to in this report.

Higher temperatures eliminate moisture and volatile elements Telephone: (202) 208-2719 Research is currently underway to improve the existing matter from coal has not been used for very many purposes, Cases of mercury poisoning trace amounts of a variety of other elements.
