Coal is physically, chemically, and thermally altered peat. Peat is partially decayed plant material, mineral matter, and water, which accumulates in anoxic swamps or mires (peatforming wetlands). Peats generally have organic contents greater than 75%, inorganic mineral contents less than 25%, and water contents of 7590% (Schopf 1966; Jarrett 1983; Clymo 1987; Alpern and deSousa 2002).

Types of Coal. The process by which something changes under the effect of pressure and temperature is known as metamorphism in geology. Coal is classified into different types based on the different stages of metamorphism undergone by it. Peat Peat is not coal, but a precursor to it. Peat is partially decomposed plant matter that has a ...

How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, lowcarbon peat, to coal, an energy and carbondense black or brownishblack sedimentary rock.

This process is referred to as 'coalification'. ... Initially peat, the precursor of coal, was converted into lignite or brown coal a coal type with low organic 'maturity'. ... As this process continued, further chemical and physical changes occurred causing these coals to become harder and more mature, at which point they are classified as ...

Coal is a combustible rock mainly composed of carbon along with variable quantities of other elements, mostly hydrogen, sulphur, oxygen and nitrogen. Coal occurs as layers, called coal beds or coal seams, that are found between other sedimentary rocks. Coal is slightly denser than water but less dense than most of the rocks of the Earth's crust ...

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.

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...

Specifically, peat compacts to form solid rock through a process called lithification, producing lignite (brown coal, a lowquality form of coal). With increasing heat and pressure, lignite turns to subbituminous coal and bituminous coal. Lignite, subbituminous coal, and bituminous coal are considered sedimentary rocks because they from from ...

How does coal become peat? 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.

As it got buried deeper, the pressure of the rock above would squeeze the peat flat, pushing out much of the water. The rock will warm up as it gets buried deeper (the earth is hot inside) and this will cause chemical reactions to change the peat into coal. Coal is fossilised plant material.

The weight of the sediment caused the peat to become compressed, and the heat and pressure from the overlying sediment caused the peat to undergo chemical changes that transformed it into coal. 4.

Heating causes hydrocarbon compounds (compounds composed of hydrogen, carbon, and oxygen) in the peat to break down and alter in a variety of ways, resulting in coal. In general, moisture and gases (for example, methane, carbon dioxide) are systematically expelled from the peat and resulting coal with increasing burial and heat.

Introduction. Peat has been used as a form of energy for at least 2 000 years. It was useful as an alternative to firewood for cooking and heating in temperate and boreal regions of Europe, in particular Ireland, England, the Netherlands, Germany, Sweden, Poland, Finland and the USSR. The increasing use of gas and oil as cooking and heating ...

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.
