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 ...
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.
Limestone (calcium carbonate CaCO 3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO 3. Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place ...
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]
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 ...
This protected area is on Carboniferous Limestone from the Dinantian Stage. The rocks are an important source of fossils.Mining and industrial activity has occurred at this site since the nineteenth century, resulting in a landscape modified by spoil heaps and discarded stone. [3]
Carboniferous Limestone, of marine origin, covers the sandstone and appears in the Avon Gorge and at Weston-super-Mare where it contains volcanic rocks. [37] There are outlying hills at Worlebury, Middle Hope, the Failand Ridge, Broadfields Down, Portishead Down and Wrington Hill. The main geological component of the Mendips is Carboniferous ...
