Peat is effectively a low-grade coal. The difference is that the plant material has been compacted under less pressure, and for less time. Here's the process:
- Plants thrive during an interglacial period, or because of a circumstantial warm breeze giving the right conditions. The best conditions are in marshy deltas.
- For whatever reason, the plants all die, and the dead, decomposing material is covered before it has been totally degraded, sealing it from oxygen.
- Over tens of thousands of years, layers of material build up on top of the material, building downward pressure on it, as well as heat. This pressure increases the proportion of carbon in the material.
- Eventually, the now peat has become a fairly solid material. Over hundreds of thousands of years, it will become coal.
The peat may surface at some point because of tectonic forces causing uplift, or some other cause of exposure to the surface.
Peat is formed from partially decomposed organic matter in waterlogged environments with limited oxygen, like peatlands. Over time, the accumulation of dead plant material like mosses and ferns gets compacted and undergoes slow decomposition, forming peat layers. The process can take thousands of years.

Is milled peat found at the bottom of the bog?
No, milled peat is not found at the bottom of the bog. Peat is formed from partially decomposed plant material that accumulates at the surface of bogs over time. Milled peat is extracted from the upper layers of the bog.
How long will peat last before it runs out?
The timescale for peat depletion depends on factors such as the rate of extraction and regeneration of peat bogs. However, at current extraction rates, peat reserves are being depleted faster than they are being formed. It is estimated that peat reserves could be exhausted in the next few hundred years if current practices continue.
What does the presence of peat in glacial till tell us?
The presence of peat in glacial till suggests that the area was once covered by wetlands or marshes where peat formed. This can give clues about the past environmental conditions and the type of vegetation that was present in that area.
Is formed of the remains of plants that lived in swamps?
Coal is formed of the remains of plants that lived in swamps millions of years ago. As these plants died and decomposed, they were eventually transformed into peat, and over time, through heat and pressure, the peat transformed into coal.
Second stage soft brown rock formed by layers of sand and mud that covers peat?
The second stage soft brown rock formed by layers of sand and mud covering peat is likely shale. Shale is a sedimentary rock composed of clay minerals and is formed from the compaction of mud or silt over long periods of time. It is commonly found in sedimentary basins where layers of organic matter like peat are buried and compressed.
Is peat found in swamps?
Yes, peat is found in swamps. Peat is formed in swamps. Moss is found hanging from trees in swamps. Have you heard the term "peat moss"........
Is Peat thought to be the original material from which coals are formed?
yes
What is formed when pressure sqeezes moisture out of peat?
Dried peat. Only after subsequent layers of sediments have been deposited on top, year after year, century after century, eon after eon, will the pressure lithify the peat into coal.
Does peat contain carbon?
Yes, peat contains a significant amount of carbon. It is formed from the accumulation and partial decay of plant material in waterlogged conditions, which results in a high carbon content.
Is milled peat found at the bottom of the bog?
No, milled peat is not found at the bottom of the bog. Peat is formed from partially decomposed plant material that accumulates at the surface of bogs over time. Milled peat is extracted from the upper layers of the bog.
Can peat float in water?
Yes, peat can float in water due to its low density and high organic content. Peat is formed from partially decayed organic matter and often contains trapped air pockets that make it buoyant.
Where is coal begin to form from?
Coal is formed from plants, which turned into peat, then lignite, then coal.
How long will peat last before it runs out?
The timescale for peat depletion depends on factors such as the rate of extraction and regeneration of peat bogs. However, at current extraction rates, peat reserves are being depleted faster than they are being formed. It is estimated that peat reserves could be exhausted in the next few hundred years if current practices continue.

Coal is formed of the remains of plants that lived in swamps millions of years ago. As these plants died and decomposed, they were eventually transformed into peat, and over time, through heat and pressure, the peat transformed into coal.
How were the Norfolk broads formed?
The Norfolk Broads were formed around 7,000 years ago by the flooding of medieval peat excavations. These excavations created a network of shallow lakes and waterways that are now a popular destination for boating and wildlife enthusiasts in Norfolk, England.
What is the difference between peat based compost and peat free compost?
Peat adds acid. So, if you need to add acid to your soil, you want to use something with peat. We added peat to our blueberry plantings. If you don't need the acid, then get the peat-free stuff. Peat based compost,as the name suggests, contains peat. Peat free compost does not contain peat but some other organic matter. This excercise is driven by the Green lobby who fear that the planet will run out of peat and implode.
