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.
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 ...

Frosterley Marble is a black, bituminous coraliferous limestone containing fossil crinoids of the Lower Carboniferous (Mississippian ), some 325 million years ago. [ 1 ] [ 2 ] : 40 It outcrops in Weardale , County Durham , England, including near the village of Frosterley whence it is named.
The Group comprises a lower unit of coarse sandstones, siltstones, mudstone, and limestones with thin coals and ironstones known as the Lower Limestone Formation, an overlying sequence of similar rocks known as the Limestone Coal Formation, then an Upper Limestone Formation and at its top the sandstones of the Passage Formation.
