Other articles where coalification is discussed: coal: Peat: The process of peat formation—biochemical coalification—is most active in the upper few metres of a peat deposit. Fungi are not found below about metre (about 18 inches), and most forms of microbial life are eliminated at depths below about 10 metres (about 30 feet). If either the rate of.

The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or "ranks," of coal are determined by carbon content. There are four ...

Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the largescale exploitation of coal deposits. Since the mid20th century, coal has yielded its place to petroleum and natural ...
