The Carboniferous Limestone at Llangollen is from the Visean Stage of the Dinantian (Lower Carboniferous) which is of Chadian- Brigantian Substage. It is part of the Clwyd Limestone Group, which is about myrs old. There are a diverse range of limestone facies, exhibiting local dolomitisation, with subordinate sandstone and mudstone units. National Library of Wales holds Carto Cymru – The Wales Map Symposium – Charting the Seas. On the 18 May , Carto-Cymru – The Wales Map Symposium Charting the Seas will take place at The National Library of Wales, Aberystwyth.. The conference will show how maps depict the sea and coastline and how such mapping is used to widen our understanding of these environments.

In geology, the Llandeilo Group is the middle subdivision of the British Ordovician rocks. It was first described and named by Sir Roderick Murchison from the neighborhood of Llandeilo in the type area it consists of a series of slaty rocks, shales, calcareous flagstones and sandstones; the calcareous middle portion is sometimes termed the Llandeilo limestone; and in the.
Llandeilo, on the coach road from Brecon to West Wales and also to South Wales, drew many travellers in the 18 th and early 19 th century.
Before the two mainline coaches were: from London via Gloucester, Brecon and Llandeilo to Carmarthen. from London to Bristol, Swansea and Pontardulais to Carmarthen.
There were of course lesser routes. The cliffs at the north end of Musselwick Sands, m north-west of Marloes Church (SM ), where beds which are possibly from the middle or lower part of the Gray Sandstone Group are faulted to the south against Llandeilo Flags (Ordovician) and to the north against Old Red Sandstone by: South Wales Coalfield.
This initiative is drawing on archival coal seam data and new information to develop an interactive 3D model of the South Wales coalfield, which has a range of applications in the research of new clean coal technologies for the energy sector.
Thus, graptolite biostratigraphy is a foundation for the stratigraphic correlation of strata in both Northwest China and elsewhere in the world.
In the following section, we use the graptolite faunal distribution in Northwest China to define biozonations by region, from west to east through this vast area. Early Ordovician (Arenig) stratigraphy and faunas of the Carmarthen district, south-west Wales by R A Fortey; R M Owens.

South Wales is an area with many features of outstanding interest to geologists, who have for long used the area for University field trips.
This varied and accessible region has provided a written record of geological interest that dates to the 12th century, when Giraldus Cambrensis noted pyritous shales near Newport. Some of the first published representations of fossils were of fossil.

The global standard for the Llandovery Series (early Silurian) in centralWales is re-assessed in the light of detailed geological surveying, biostratigraphical sampling and a rigorous examination of published datasets.
A new sedimentary and biostratigraphical architecture is presented. Key graptolite, brachiopod, acritarch and, for the first time, chitinozoan assemblages are critically assessed.

The geology of north-east Wales tells a million year story of deep-sea muds crumpled and fractured by earth-movements, shallow tropical seas teeming with life, swamps with giant mosses, vast hot and barren deserts periodically inundated by flash floods and, in the relatively recent past, vast ice sheets sculpting the landscape.
In earliest Lower Palaeozoic times, Wales, together with Belgium, England, southern Ireland and the Avalon area of eastern Newfoundland, formed part of a north-west-facing continent on the south-east side of the Iapetus Ocean at a latitude between 40° and 60° intense volcanic, tectonic and metamorphic activity that occurred at the edge of this continent in late Precambrian times.
June: The Carboniferous Period (Part 2.) Later in the Carboniferous period, in the Late Namurian to ‘Westphalian Epochs’, clastic sediments continued to accumulate around the margins of the Wales-Brabant landmass, and ‘prograded’ outwards into the marine basins to the north and south, eventually filling them with sediment to form low lying ‘delta top’ and coastal plain landscapes.

Abstract - Re-mapping during of the Upper Devonian on the Parkes and Grenfellmap sheets was the first systematic field examination of this area by an experienced vertebrate.

The Upper Llandovery has local lenticular developments of shelly limestone (Norbury, Hollies and Pentamerus limestones). It occurs with a narrow outcrop in Carmarthenshire at the base of the Silurian, disappearing beneath the Old Red Sandstone westward to reappear in Pembrokeshire; north-eastward the outcrop extends to the Long Mynd, which the conglomerate wraps round.

Conodont and goniatite biostratigraphy has been traditionally used to locate these events; but age diagnostic material in the backreef and restricted facies is rare. Recent studies have indicated the usefulness of microvertebrates as biostratigraphic substitutes in such environments.

The geology of Wales is complex and varied; its study has been of considerable historical significance in the development of geology as a geological periods from the Cryogenian (late Precambrian) to the Jurassic are represented at outcrops, whilst younger sedimentary rocks occur beneath the seas immediately off the Welsh coast.
The effects of two mountain-building episodes have. Carboniferous rocks crop out southwards from the Scottish border through the Pennines and into the Midlands, in Wales, and in the south-west peninsula.
Perhaps more than any other geological system, this is the unit that has been plundered for our economic development providing the materials that fuelled the Industrial Revolution of the 18th and 19th centuries — coal, iron, refractory clay.
