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 ...
This section is a list of generic types of limestone. 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 ...
The Greenbrier Limestone, also known locally as the "Big Lime", is an extensive limestone unit deposited during the Middle Mississippian Epoch (345.3 ± 2.1 – 326.4 ± 1.6 Ma), part of the Carboniferous Period.

Gaping Gill contains a waterfall disappearing underground into the Carboniferous limestone. The formation of Carboniferous Limestone was followed by the deposition of dark marine shales, siltstones and coarse sandstones of the Millstone Grit, notably in the area later uplifted to form the Pennine anticline. This sequence can be seen in the ...
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 ...
The earliest Carboniferous rocks, the Village Farm and Jackie Parr Limestone formations, are seen in the Lilleshall inlier where they unconformably overlie the Old Red Sandstone sequence. These are in turn overlain unconformably by the Lydebrook Sandstone and Sylvan Limestone formations. Within the latter is the Little Wenlock Basalt.
