The Carboniferous Period

The Carboniferous Period The Carboniferous Period is famous for its vast swamp forests, such as the one depicted here. Such swamps produced the coal from which the term Carboniferous, or "carbon-bearing," is derived. The Carboniferous Period lasted from about 359.2 to 299 million years ago* during the late Paleozoic Era.

About: Carboniferous

The Carboniferous is a geologic period and system that spans 60 million years from the end of the Devonian Period 358.9 million years ago (Mya), to the beginning of the Permian Period, 298.9 Mya. The name Carboniferous means "coal-bearing" and derives from the Latin words carbō ("coal") and ferō ("I bear, I carry"), and was coined by

2020-11-23  Carboniferous The period of the Carboniferous (359 to 299 million years ago) can roughly be divided in two: the early Carboniferous with the formation of thick layers of limestone, and the late Carboniferous, with extensive peat bogs that were transformed into coal by deep burial.

THE EBBADALEN FORMATION (CARBONIFEROUS),

The Ebbadalen Formation (Carboniferous) of Spitsbergen lies in an elongated basin on the downthrown side of the Billefjorden Fault Zone. Apart from the lower part of the formation, where all the beds are clastic, evaporites dominate in the basin and separate red beds, adjacent to the fault-belt, from marine carbonates. Several unconformities are recorded within the formation towards the

2018-2-3  Carboniferous comes from the Coal Measures (which are a part). Permian is from Perm in Russia. Triassic is from the 3 parts of the rocks of this age in Germany. Jurassic comes from the Jura Mountains in SE France.

Scratching the surface: Footprint of a late

In the Karoo Basin of South Africa, there has been a tradition of investigation of late Paleozoic ice age (LPIA) deposits of the Dwyka Group stretching back a century (Du Toit, 1921), with groundbreaking work on paleogeographic reconstructions and facies analysis in the 1980s and 1990s (Visser, 1983, 1987, 1989, 1990, 1997; Visser and Kingsley, 1982).

International Commission on Stratigraphy

The Carboniferous is a geologic period and system that extends from the end of the Devonian Period, about 358.9 ± 0.4 Ma, to the beginning of the Permian Period, about 298.9 ± 0.2 Ma. The Carboniferous System has been subdivided into two subsystems, the Mississippian and the Pennsylvanian, and contains seven global stages.

Carboniferous Period Geology Page

The early part of the Carboniferous was mostly warm; in the later part of the Carboniferous, the climate cooled. Glaciations in Gondwana, triggered by Gondwana’s southward movement, continued into the Permian and because of the lack of clear markers and breaks, the deposits of this glacial period are often referred to as Permo-Carboniferous in age.
