Coal and Peat

Coal mining

Coal has a fascinating origin that dates back hundreds of millions of years. This fossil fuel comes from enormous plants and ferns that once thrived in marsh forests. When these plants and ferns died and decomposed, they created layers of organic matter at the swamp’s base.

Over time, the layers of decomposed organic matter were covered by water and dirt. It created immense pressure and high temperatures, forcing changes in decaying plants and ferns’ chemical and physical structures. As a result, the oxygen was pushed out of these layers, and the plants and ferns continued to deteriorate until they formed coal.

Peat is a precursor to coal formed by accumulated dead plant matter in flooded areas over thousands of years. These areas have poor drainage or experience frequent flooding, leading to the formation of peatlands. Peat transforms into coal over time through ongoing vegetation growth and low oxygen levels.
