    For peat to become coal, it must be buried by sediment. Burial compacts the peat and, consequently, much water is squeezed out during the first stages of burial. Continued burial and the addition of heat and time cause the complex hydrocarbon compounds in the peat to break down and alter in a variety of ways. The gaseous alteration products are typically expelled from the deposit and the deposit becomes more and more carbon-rich as the other elements disperse. Lignite coal is the lowest grade of coal and is brownish-black in appearance. This coal forms from organic carbon in plant material like peat. As peat is squeezed at low temperatures it is considered a sedimentary rock, unlike a metamorphic rock that is subjected to greater temperatures and pressures causing profound physical or chemical change.…
