Coal can also be defined as a rock having 70% or more by volume (or 50% or more by weight) carbonaceous material formed by the compaction of various plant remains over time underground. There are various types of coal based on three major factors: The type of plant material that forms the coal (this defines the coal type)

The younger era of coal formation began about 145 million years ago, during the Cretaceous Period, and reached its peak approximately 66 million to 2.6 million years ago, during the Paleogene and Neogene periods of the Cenozoic Era. Most of the coals that formed during this later era are lignites and subbituminous (brown) coals.

The first step in the formation of coal is the build up decomposed plant debris known as peat. Peat is a complex hydrocarbon that is the building block for coal. There are several factors that influence the formation of peat. The first two factors are "the evolutionary development of plant life" and the climate conditions.

22/01/2016Coal, as dead plant matter, is obviously based in short-term biological processes. And yet, as an important part of the long-term carbon cycle, coal accumulation is largely dictated by geological processes that operate on timescales of many millions of yearsthat are entirely independent of the biology.

Coal is a non-clastic sedimentary rock. They are the fossilized remains of plants and are in flammable black and brownish-black tones.
