The second theory is that the geographical setting and climate of the Carboniferous were unique in Earth's history: the co-occurrence of the position of the continents across the humid equatorial zone, high biological productivity, and the low-lying, water-logged and slowly subsiding sedimentary basins that allowed the thick accumulation of ...

Subdivisions of the Carboniferous system in Europe compared with the official ICS-stages (as of 2018) The Westphalian is a regional stage or age in the regional stratigraphy of northwest Europe, with an age between roughly 315 [ 1 ] [ 2 ] and 307 [ 1 ] [ 3 ] Ma (million years ago) .
The Carboniferous extends from about 358.9 ± 0.4 to about 298.9 ± 0.15 Ma. [10] A global drop in sea level at the end of the Devonian reversed early in the Carboniferous; this created the widespread epicontinental seas and carbonate deposition of the Mississippian. There was also a drop in south polar temperatures; southern Gondwana was ...
The strata become gradually younger from west to east. [1] [2] Much of Yorkshire presents heavily glaciated scenery as few places escaped the direct or indirect impact of the great ice sheets as they first advanced and then retreated during the last ice age. A simplified geology of Yorkshire
The exploitation of the Coal Measures and other Carboniferous age strata in the Ironbridge area made it one of the birthplaces of the Industrial Revolution. There is also a large amount of mineral wealth in the county, including lead and baryte. Quarrying is still active, with limestone for cement manufacture and concrete aggregate, sandstone ...
The work describes the Carboniferous strata in the north-east in their vertical sequence as discovered during mining operations and discusses their lateral variations. It presents the first long composite stratigraphic section at the scale of an entire geological system, representing over 1000 m of section, combining mine records between Cross ...
The Pennine Coal Measures Group is a lithostratigraphical term referring to the coal-bearing succession of rock strata which occur in the United Kingdom within the Westphalian Stage of the Carboniferous Period.
