Coalification is the process by which peat is transformed into coal. The process of transforming vegetable matter into coal usually occurs in two main steps: the biochemical and the physicochemical stage of coalification (Stach et al. 1982; Diessel 1992). In the biochemical stage, organisms initiate and assist in the chemical decomposition of ...

Peat is the first step in the formation of coal, and slowly becomes lignite after pressure and temperature increase as sediment is piled on top of the partially decaying organic matter. In order to be turned into coal, the peat must be buried from 410 km deep by sediment. [2] Since peat becomes coal over time, it is classified as a fossil product.

Peat forms during glacial periods, when the polar ice sheets grow and the sea level falls. Then, when the ice melts and the sea floods into the swamps, the peat is preserved, locked away beneath new marine sediment. In some places, the rock record attests to dozens of these repeating marine and nonmarine layers, known as cyclothems.

Although peat is used as a source of energy, it is not usually considered a is the precursor material from which coals are derived, and the process by which peat is formed is studied in existing swamps in many parts of the world (, in the Okefenokee Swamp of Georgia,, and along the southwestern coast of New Guinea).The formation of peat is controlled by several factors ...

Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate electricity. It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel ...

For the 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.

Peat and Peatification. Peat is soillike, partially decayed plant material that accumulates in wetlands. Most people learn that coal is formed in swamps, but this is not completely accurate. The term "swamps" can be applied to many different types of wetlands, but coal only forms from peataccumulating wetlands.

Peat moss (Sphagnum) is one of the most common constituents of peat. Peatification is influenced by several factors, including the nature of the plant material deposited, the availability of nutrients to support bacterial life, the availability of oxygen, the acidity of the peat, and wetlands result from high groundwater levels, whereas some elevated bogs are the result of ...

By studying how coal forms, scientists can learn both about the deep past and about what to expect when different coals burn. Coal forms when swamp plants are buried, compacted and heated to become sedimentary rock in a process called coalification. "Very basically, coal is fossilized plants," James Hower, a petrologist at the University of ...

It is important to remember, though, that coal takes a very long time to form from peat because the peat has to become very compact. It is estimated that for every 1 vertical foot of coal mined from Kentucky, it took 10 vertical feet of original peat material to produce it.

Coalification is a chemical process in which hydrogen and oxygen are lost from the original peat fool, increasing the ratio of carbon to other elements. This involves alteration to the remaining molecules of the material, in particular the conversion of lignin to vitrinite. Coalification is not an allornothing process: rather it produces coal ...
