Moel Penderyn
Moel Penderyn is a hill on the edge of Penderyn village, in the Brecon Beacons National Park in the county borough of Rhondda Cynon Taff, south Wales. It also appeared on older maps as 'Y Foel Penderyn'. Its summit at 371m is marked by a trig point. Moel Penderyn is in the ''Dyffrynnoedd Nedd a Mellte, a Moel Penderyn'' biological and geological Site of Special Scientific Interest. Geology The hill is formed from both Carboniferous Limestone rocks and the overlying Twrch Sandstone (former 'Basal Grit') of the Marros Group (former ' Millstone Grit Series'), also of Carboniferous age. It lies along the east-northeast to south-southwest aligned Neath Disturbance, a geological structure associated with the Caledonian Orogeny which locally comprises both a major fault and two tight anticlinal folds.British Geological Survey 1:50,000 map sheet 231 'Merthyr Tydfil' & accompanying memoir Industrial remains The remains of tramways Tramway may refer to: * Tramway (industrial), a l ...

Waterfall Country (Wales)
Waterfall Country (or sometimes Waterfalls Country) is an English name often given to the Vale of Neath in South Wales. The tourist area around the head of the valley has an unusually large number of publicly accessible waterfalls. The area is not officially defined but generally includes the group of falls on the Nedd Fechan, Pyrddin, Hepste and Mellte rivers, all of which lie between the villages of Pontneddfechan and Ystradfellte in the Brecon Beacons National Park. Each of these falls lies within or on the boundary of the county of Powys. A few miles further west are Henrhyd Falls on the Nant Llech, a tributary of the Tawe and to the south-west are Melin Court Falls on the Melin Court Brook, a tributary of the River Neath. These, along with Aberdulais Falls on the Dulais, a further tributary of the Neath are also encompassed by the term 'Waterfall/s Country' by some writers. Collectively the falls are one of the more popular natural attractions in South Wales, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tramway (industrial)
Tramways are lightly laid railways, sometimes with the wagons or carriages moved without locomotives. Because individual tramway infrastructure is not intended to carry the weight of typical standard-gauge railway equipment, the tramways over which they operate may be built from less substantial materials. Tramways can exist in many forms; sometimes just tracks temporarily placed on the ground to transport materials around a factory, mine or quarry. Many, if not most, use narrow-gauge railway technology. The trains can be manually pushed by hand, pulled by animals (especially horses and mules), cable hauled by a stationary engine, or use small, light locomotives. The term is not in use in North America but in common use in the United Kingdom, and elsewhere, where British Railway terminology and practices had large influences on management practices, terminology, and railway cultures such as Australia, New Zealand, and those parts of Asia that consulted with British experts whe ...

Fold (geology)
In structural geology, a fold is a stack of originally planar surfaces, such as sedimentary strata, that are bent or curved during permanent deformation. Folds in rocks vary in size from microscopic crinkles to mountain-sized folds. They occur as single isolated folds or in periodic sets (known as ''fold trains''). Synsedimentary folds are those formed during sedimentary deposition. Folds form under varied conditions of stress, pore pressure, and temperature gradient, as evidenced by their presence in soft sediments, the full spectrum of metamorphic rocks, and even as primary flow structures in some igneous rocks. A set of folds distributed on a regional scale constitutes a fold belt, a common feature of orogenic zones. Folds are commonly formed by shortening of existing layers, but may also be formed as a result of displacement on a non-planar fault (''fault bend fold''), at the tip of a propagating fault (''fault propagation fold''), by differential compaction or due ...

Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A '' fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can bl ...

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. ...

Neath Disturbance
The Neath Disturbance is a geological structure which stretches across south Wales from Swansea Bay northeastwards as far as Hereford in western England. It consists of a series of both faults and associated folds which were active during the mountain-building period known as the Variscan orogeny. This line of weakness probably featured in the earlier Caledonian Orogeny and perhaps reflects a more ancient line of weakness in the basement rocks. The Disturbance gives rise to a lineament crossing the region, that is to say that it is responsible for a number of significant landscape features along its 100 km length. Prominent amongst these is the Vale of Neath, a deep valley incised by a glacier during the ice ages along this line of weakness in the Earth's crust and now occupied by the River Neath between Pontneddfechan and Swansea Bay. The hill of Moel Penderyn also lies on the Disturbance a little further east. A part of the Vale of Grwyne north of The Sugarloaf and ...

Carboniferous
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago (Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' (" coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian lin ...

Marros Group
The Marros Group is the name given to a suite of rocks of Namurian age laid down during the Carboniferous Period in South Wales. These rocks were formerly known as the Millstone Grit Series but are now distinguished from the similar but geographically separate rock sequences of the Pennines and Peak District of northern England and northeast Wales by this new name. Stratigraphy The Group comprises a thick unit of coarse sandstone known as the Twrch Sandstone (formerly the ‘Basal Grit’) which is overlain by the Bishopston Mudstone and the Telpyn Point Sandstone. The mudstones of these latter two formations was formerly known as the ‘Middle Shales’, a name reflecting the position of this sequence sandwiched between the Basal Grit below and the Farewell Rock, the lowermost sandstone of the South Wales Coal Measures, above. The mudstone itself contains a few bands of sandstone such as the ‘Twelve Foot Sandstone’ and locally the ‘Cumbriense Sandstone’. Likewise th ...

Penderyn, Rhondda Cynon Taf
Penderyn is a rural village in the Cynon Valley, Rhondda Cynon Taf, Wales, located near Hirwaun. Location The village lies on the A4059 road between Hirwaun and Brecon and is the last settlement on that road in the county of Rhondda Cynon Taf before the border with Powys to the north. The village sits just within the southern boundary of the Brecon Beacons National Park. The River Cynon passes through the area. There are four disused churches and chapels in Penderyn: Jerusalem Chapel (Calvinistic Methodist, now a house), Siloam Chapel (Baptist, a grade II listed building), Soar Chapel (Independent, now an antiques shop) and St Cynog's Church (Church in Wales). Penderyn is the home of Penderyn Whisky, whose distillery is located opposite the local school. The award-winning single malt whisky was launched in 2004 and was the first distilled in Wales for over 100 years. Etymology Penderyn contains two Welsh words: * ''Pen'', meaning 'head (of)' * and 'deryn', an abbreviatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carboniferous Limestone
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 million years ago. Within England and Wales, the entire limestone succession, which includes subordinate mudstones and some thin sandstones, is known as the Carboniferous Limestone Supergroup. Depositional basins Within Great Britain the suite of rocks known traditionally as the Carboniferous Limestone Series was deposited as marine sediments in three distinct ‘provinces’ separated by contemporary landmasses. One of these landmasses was the Wales-London-Brabant Massif, an east–west aligned belt of land stretching through central Wales and the English Midlands to East Anglia and on into Belgium. The limestones deposited to its south form a distinct South Wales-Mendip province which extends from Pembrokeshire in the west ...
