Historical Geology/Peat and coal - Wikibooks, .

26.10.2017 · There is, then, no real doubt that coal has its origins as plant matter. We turn now to the question of why geologists ascribe the source of this plant matter to swamps. In the first place, coalfields are just what we would expect to see if peat deposits were buried to a sufficient depth, since, as we have observed, heat and pressure, which are both produced by deep burial, cause the chemical ...

ORIGIN of COAL |authorSTREAM

It is derived from the cell-wall material or woody tissue of the plants from which coal was formed. Chemically, it is composed of polymers, cellulose etc. The vitrinite group, which consists of various individual Vitrinite macerals is the most common component of coals.

Unconventional Geology: Origin of black coal

The paradigm is that coal is essentially a product formed through the burial of plants and, according to this conventional view, the common presence of plant fossils associated with coal deposits therefore would explain intrinsically throught biogenic origin. However, there are much evidences related to the coal origin that are not yet understood.

As nouns the difference between peat and coal is that peat is soil formed of dead but not fully decayed plants found in bog areas or peat can be (obsolete) a pet, a darling; a woman while coal is (uncountable) a black rock formed from prehistoric plant remains, composed largely of carbon and burned as a fuel. As a verb coal is to take on a supply of coal (usually of steam ships).

Coal - its origin and occurrence Types of Coal. Peat is included under this heading because, as we have seen, it is the first stage in the formation of coal (though if it is not deeply buried, it will never become coal). The type of peat usually dug for fuel consists of the partly decayed reeds and mosses growing in bogs. Peat bogs, often called 'mosses', are found in Ireland, Scotland and ...

As the peat is aged and buried deeper in the ground the slow coalification process continues and eventually transforms peat into a low rank lignite coal. This brown/black coal is a young coal and so with further maturation, long time periods and warmer temperatures (within the earth) and higher pressure as the coal is buried deeper, produces the other ranks of coal: subbituminous, then ...

Peat - Wikipedia

Peat (/ p iː t /), also known as turf (/ t ɜːr f /), is an accumulation of partially decayed vegetation or organic matter.It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem is the most efficient carbon sink on the planet, because peatland plants capture CO 2 naturally released from the peat, maintaining an equilibrium.
