Peat is composed of plant materials that accumulate in wetlands ( bogs and fens), which break down through the process of peatifiion. If peats are buried, then the peats can be altered into different ranks of coal through the process of coalifiion.
WhatsApp: +86 18203695377WEBCoal Plant Matter, Carbonization, Sedimentary Rocks: It is generally accepted that most coals formed from plants that grew in and adjacent to swamps in warm, humid regions. Material derived from these plants accumulated in lowlying areas that remained wet most of the time and was converted to peat through the activity of microorganisms. (It should .
WhatsApp: +86 18203695377WEBAs the peat is aged and buried deeper in the ground the slow coalifiion process continues and eventually transforms peat into a low rank lignite coal.
