2019-2-17 · Oil or petroleum is a readily combustable fossil fuel that is composed mainly of carbon and hydrogen, and is thus known as a hydrocarbon. The formation of oil takes a significant amount of time with oil beginning to form millions of years ago. 70% of oil deposits existing today were formed in the Mesozoic age (252 to 66 million years ago), 20% were formed in the Cenozoic age (65 million years ...

THE FORMATION OF COAL

The formation of coaloccurs over the course of a very long period. Most of the coal that people mine and use today was formed around 300 to 400 million years ago. Coal is basically the decayed remains of plant matter that was once thriving and has undergone a process sometimes referred to as coalification.

How coal is formed

2020-2-21 · Instead of releasing carbon and oxygen into the air, it created perfect conditions for coal formation from these fallen trees. This is because all the carbon remained in the wood to become the prime ingredient in hydrocarbons. So, for 60 million years, this natural process laying down vast swamp forests under sediment continued.

2007-1-4 · The Coal Formation Process. Coal Formation starts with accumulation of organic matter (bits of dead plants) in a low oxygen setting such as a peat bog. The organic matter accumulates and forms a bed of peat. The peat bed gets buried by other sediments and under heat and pressure begins to transform to a low grade coal - a Lignite.

The formation of kerogen is a key component of the fossil fuel development process. Following a lengthy process of years of compacting carbonaceous matter (plants, animals, and other organisms that contain carbon), the complex and waxy mixture of hydrocarbon compound known as kerogen began to form.

Coalification | geology | Britannica

Coal beds consist of altered plant remains. When forested swamps died, they sank below the water and began the process of coal formation. However, more than a heavy growth of vegetation is needed for the formation of coal. The debris must be buried, compressed and protected from erosion.
