Carboniferous Limestone is a collective term for the succession of limestones occurring widely throughout Great Britain and Ireland that were deposited during the Dinantian Epoch of the Carboniferous Period. These rocks formed between 363 and 325 million years ago.
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 ...

Dinantian is the name of a series or epoch from the Lower Carboniferous system in western Europe between 359.2 to 326.4 million years ago. [1] It can stand for a series of rocks in Europe or the time span in which they were deposited.
The geology of the Yorkshire Dales National Park in northern England largely consists of a sequence of sedimentary rocks of Ordovician to Permian age. The core area of the Yorkshire Dales is formed from a layer-cake of limestones, sandstones and mudstones laid down during the Carboniferous period.
Carboniferous: Middle Limestone Group / Hardrow Scar Limestone III Cyclothem Formation: Carboniferous: Middle Limestone Group / Hardrow Scar Limestone IIIa Formation: Carboniferous: Middle Limestone Group / Hardrow Scar Limestone IIIb Formation: Carboniferous: Middle Limestone Group / Hardrow Scar Limestone IIIc Formation: Carboniferous
The sequence includes Carboniferous Limestone at its base, followed by coarse sandstones (The ‘Millstone Grit’ of the north and the ‘Twrch Sandstone’ of the south), then mudstones and finally the Coal Measures which comprise a thick succession of mudstones, sandstones and of course coal seams.
