Carboniferous Limestone exposed at Ogmore-by-Sea, Wales. Carboniferous/Jurassic unconformity. 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 ...
Sutton stone has always been highly regarded: as well as being used in construction throughout the Vale of Glamorgan, it was also shipped over the Bristol Channel to North Devon and North Cornwall, which are both deficient in limestone. A major geological feature of the Upper Carboniferous rocks in south Wales is the south Wales coalfield. The ...
Bituminous limestone; Carboniferous Limestone – Limestone deposited during the Dinantian Epoch of the Carboniferous Period; Coquina – Sedimentary rock that is composed mostly of fragments of shells; Coral rag – Limestone composed of ancient coral reef material; Chalk – Soft carbonate rock; Fossiliferous limestone – Limestone ...
The Carboniferous Limestone is overlain by a suite of rocks traditionally referred to as the Yoredale Series, and named from 'Yoredale' (an older name for Wensleydale), these are divided into an upper/younger Stainmore Formation and a lower/older Alston Formation.
Around 360 Ma, at the start of the Carboniferous period, Great Britain was lying at the equator, covered by the warm shallow waters of the Rheic Ocean, during which time the Carboniferous Limestone was deposited, as found in the Mendip Hills, north and south Wales, in the Peak District of Derbyshire, north Lancashire, the northern Pennines and ...
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.
Limestone pavement above Malham Cove. The Pennines form an anticline which extends in a north–south direction, consisting of Millstone Grit and the underlying Carboniferous Limestone. The limestone is exposed at the surface to the north of the range in the North Pennines AONB. [3]
The geology of the Peak District National Park in England is dominated by a thick succession of faulted and folded sedimentary rocks of Carboniferous age. The Peak District is often divided into a southerly White Peak where Carboniferous Limestone outcrops and a northerly Dark Peak where the overlying succession of sandstones and mudstones dominate the landscape.
