Central Wales Syncline
The Central Wales Lineament is a north–south aligned zone of geological faults and folds which runs for scores of miles through Wales and which gives rise to a number of landscape features. The lineament lies along the axis of the Central Wales Syncline, both following the generally northeast–southwest Caledonide trend though its central section is more north–south aligned. The Tafolog Fault which runs north from Llanbrynmair is one component structure in the central section of the lineament and along which Cwm Tafolog has been eroded. The Dylife Fault, a southerly continuation of the same fault is coincident with the valley of the Afon Twymyn. The section of the valley east of the former lead-mining village of Dylife is spectacularly incised into the landscape making this one of the most readily recognisable parts of the lineament. The lineament continues southwards as a series of offset north–south faults, crossing the Wye valley just west of Llangurig. The lineament cont ...

Wales
Wales ( cy, Cymru ) is a Countries of the United Kingdom, country that is part of the United Kingdom. It is bordered by England to the Wales–England border, east, the Irish Sea to the north and west, the Celtic Sea to the south west and the Bristol Channel to the south. It had a population in 2021 of 3,107,500 and has a total area of . Wales has over of coastline and is largely mountainous with its higher peaks in the north and central areas, including Snowdon (), its highest summit. The country lies within the Temperateness, north temperate zone and has a changeable, maritime climate. The capital and largest city is Cardiff. Welsh national identity emerged among the Celtic Britons after the Roman withdrawal from Britain in the 5th century, and Wales was formed as a Kingdom of Wales, kingdom under Gruffydd ap Llywelyn in 1055. Wales is regarded as one of the Celtic nations. The Conquest of Wales by Edward I, conquest of Wales by Edward I of England was completed by 1283, th ...

Caledonian Orogeny
The Caledonian orogeny was a mountain-building era recorded in the northern parts of the British Isles, the Scandinavian Mountains, Svalbard, eastern Greenland and parts of north-central Europe. The Caledonian orogeny encompasses events that occurred from the Ordovician to Early Devonian, roughly 490–390 million years ago ( Ma). It was caused by the closure of the Iapetus Ocean when the continents and terranes of Laurentia, Baltica and Avalonia collided. The orogeny is named for Caledonia, the Latin name for Scotland. The term was first used in 1885 by Austrian geologist Eduard Suess for an episode of mountain building in northern Europe that predated the Devonian period. Geologists like Émile Haug and Hans Stille saw the Caledonian event as one of several episodic phases of mountain building that had occurred during Earth's history. Current understanding has it that the Caledonian orogeny encompasses a number of tectonic phases that can laterally be diachronous. The n ...

Llanbrynmair
Llanbrynmair () is a village, community and electoral ward in Montgomeryshire, Powys, on the A470 road between Caersws and Machynlleth. Llanbrynmair, in area, is the second largest in Powys. In 2011, it had a population of 920. Description The community includes several hamlets: Talerddig, Dolfach, Bont-Dolgadfan, Pandy, Cringoed, Dylife and Pennant. The original centre is at Llan, on the road to Llanidloes, where the local parish church of St Mary is located. The current centre (formerly called "Wynnstay") at the junction of the A470 and B4518 rose to local prominence with the building of the new turnpike road in 1821 and the arrival of the railway line between Newtown and Machynlleth in 1861. Geographically, the community includes the valleys of three rivers – Afon Twymyn, Afon Iaen and Afon Rhiw Saeson – and the surrounding uplands. The three rivers join around the main village and flow westwards as the Afon Twymyn towards the Afon Dyfi and Cardigan Bay. The Cambrian ...

Lineament
''See also Line (geometry)'' A lineament is a linear feature in a landscape which is an expression of an underlying geological structure such as a fault. Typically a lineament will appear as a fault-aligned valley, a series of fault or fold-aligned hills, a straight coastline or indeed a combination of these features. Fracture zones, shear zones and igneous intrusions such as dykes can also be expressed as geomorphic lineaments. Lineaments are often apparent in geological or topographic maps and can appear obvious on aerial or satellite photographs. There are for example, several instances within Great Britain. In Scotland the Great Glen Fault and Highland Boundary Fault give rise to lineaments as does the Malvern Line in western England and the Neath Disturbance in South Wales. The term 'megalineament' has been used to describe such features on a continental scale. The trace of the San Andreas Fault might be considered an example.Whitten & Brooks, The Penguin Dictionary of Ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afon Twymyn
The Afon Twymyn ( en, River Twymyn, italic=yes) is a river in Powys, Mid Wales.

Dylife
Dylife is a former mining settlement in Powys, Wales, located at the head of Afon Twymyn in the Cambrian Mountains, one mile west of the road between Llanidloes and Llanbrynmair ( B4518). It is in the historic county of Montgomeryshire. The nearby lead mines intermittently sustained mining communities from Roman times until the early 20th century. During the late 19th century, as mining declined after the 1860s so did Dylife's population. The remaining buildings are two former chapels converted into homes and the Star Inn. Mining Lead mining around Dylife took place in Roman times (there is a Roman fort on nearby Penycrocbren) and recommenced in the 17th century on a small scale until the early 19th century. In 1809, the two managers, Hugh Williams and John Pughe, started to negotiate for the lease which they obtained in 1815. The two men operated the mines until the 1850s, although not harmoniously. The mines were expanded with new shafts and machinery was brought in to assi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Wye
The River Wye (; cy, Afon Gwy ) is the Longest rivers of the United Kingdom, fourth-longest river in the UK, stretching some from its source on Plynlimon in mid Wales to the Severn estuary. For much of its length the river forms part of Wales-England border, the border between England and Wales. The Wye Valley (lower part) is designated an Area of Outstanding Natural Beauty. The Wye is important for nature conservation and recreation, but is severely affected by pollution. Etymology The meaning of the river's name is not clear. Possibly the earliest reference to the name is ''Guoy'' in Nennius' early 9th Century ''Historia Brittonum'' and the modern Welsh language, Welsh name is ''Gwy''. The Wye was much later given a Latin name, ''Vaga'', an adjective meaning 'wandering'. The Tithe maps, Tithe map references a Vagas Field in both Whitchurch and Chepstow. Philologists such as Edward Lye and Joseph Bosworth in the 18th and early 19th centuries suggested an Old English derivat ...

Cwm Ystwyth
Cwmystwyth (also Cwm Ystwyth, ; en, "valley of the River Ystwyth") is a village in Ceredigion, Wales near Devil's Bridge, and Pont-rhyd-y-groes. The Ordnance Survey calculates Cwmystwyth to be the centre point of Wales (; ). History Discovery of small, oval-shaped stone tools in the area points to the fact that it has been mined for lead since the time of ancient Britons and during Roman occupation. Documentation of mining activities occurred during the reign of Elizabeth I. She engaged the services of two German miners, then went on to sub-let to Hugh Myddleton. The only significant flat area of the cwm is found before the river reaches maturity near Trawsgoed some further west. Above the village to the east steep slopes rise to the Elenydd moors, above the cwm of the Nant Milwyn, at the head of the hill of Domen Milwyn. Community Archive Wales Project Cofnodion Cwmystwyth is a recently established local history group based in Cwmystwyth. The group has 14 regular membe ...

Afon Elan
The Afon Elan ( en, River Elan) is a tributary of the River Wye which runs through the wide expanse of upland moors, traditionally known as Elenydd, in central Wales. Its valley is the Elan Valley. The name probably arises from ''elain'' meaning 'hind' or 'fawn' in reference perhaps to the rushing, bounding nature of its course. It has its source in wet moorland on the eastern flank of Pen y Deunant in Ceredigion. It is joined by Nant Dderwen, Nant Cwta and Nant Hirin before entering the top of the Elan Valley Reservoirs at Craig Goch Reservoir __NOTOC__ Craig may refer to: Geology *Craig (landform), a rocky hill or mountain often having large casims or sharp intentations.
