Key Concepts

Coal Formation

Coal is a type of sedimentary rock that forms from the burial, preservation, and transformation of organic plant material over millions of years. It is produced through a process called coalification, where accumulated plant debris in swampy environments is subjected to geological processes including heat and pressure, converting it into peat and ultimately into coal.

Carboniferous Period

The Carboniferous Period, which occurred approximately 359 to 299 million years ago, was marked by extensive swamp forests and high levels of atmospheric oxygen. This period provided ideal conditions for the proliferation and preservation of plant life, setting the stage for the massive deposits of plant material that would eventually be transformed into coal.

Plant Evolution in Paleozoic Ecosystems

During the Paleozoic Era, particularly in the Carboniferous, plant evolution was characterized by the dominance of seedless vascular plants in wetland and swampy environments. These early vascular plants, which include various types of ferns and allied groups, played a crucial role in accumulating the organic matter that later underwent fossilization to form coal.
