Mynydd Y Grug
Mynydd y Grug is a hill lying just west of the village of Cwmfelinfach and about 4 km to the northeast of Caerphilly in Caerphilly county borough in South Wales. Its summit was formerly at a height of around 358 m, but since the top has been covered by a large spoil heap and landscaped its height has now increased to 375 m, though some authorities take other values for the summit height. A number of ancient cairns are found along its edge overlooking the Sirhowy Valley, the slopes up from which are largely wooded. Geology Mynydd y Grug is formed from sandstones of the Pennant Sandstone Formation assigned to the Warwickshire Group and laid down during the latest part of the Carboniferous Period. The hill lies in the southeastern part of the South Wales Coalfield and coal seams such as the 'Dirty' and the 'Cefn Glas' have been worked around its flanks. Access The hill is crossed by a number of public footpaths, one of which is a restricted byway linking two cul-de-sac min ...

Welsh Language
Welsh ( or ) is a Celtic language family, Celtic language of the Brittonic languages, Brittonic subgroup that is native to the Welsh people. Welsh is spoken natively in Wales, by some in England, and in Y Wladfa (the Welsh colony in Chubut Province, Argentina). Historically, it has also been known in English as "British", "Cambrian", "Cambric" and "Cymric". The Welsh Language (Wales) Measure 2011 gave the Welsh language official status in Wales. Both the Welsh and English languages are ''de jure'' official languages of the Welsh Parliament, the Senedd. According to the 2021 United Kingdom census, 2021 census, the Welsh-speaking population of Wales aged three or older was 17.8% (538,300 people) and nearly three quarters of the population in Wales said they had no Welsh language skills. Other estimates suggest that 29.7% (899,500) of people aged three or older in Wales could speak Welsh in June 2022. Almost half of all Welsh speakers consider themselves fluent Welsh speakers ...

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 line ...

Blackwood, Caerphilly
Blackwood ( cy, Coed Duon) is a town, community and an electoral ward on the Sirhowy River in the South Wales Valleys administered as part of Caerphilly County Borough. It is located within the historic county of Monmouthshire. The town houses a growing number of light industrial and high-tech firms. It is the home town of influential rock band Manic Street Preachers. History Blackwood was founded in the early 19th century by local colliery owner John Hodder Moggridge, who lived at nearby Woodfield Park Estate: the first houses in Blackwood were built by Moggridge in an attempt to build a model village. Deplorable working conditions at the time of the Industrial Revolution, however, led to Blackwood becoming a centre of Chartist organisation in the 1830s. The South Wales Chartist leaders John Frost, Zephaniah Williams – a Blackwood man – and William Jones met regularly at the Coach & Horses public house in Blackwood. Planning their march on Newport in what became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rights Of Way In England And Wales
In England and Wales, other than in the 12 Inner London London boroughs, boroughs and the City of London, the right of way is a legally protected right of the public to pass and re-pass on specific paths. The law in England and Wales differs from Scots law in that rights of way exist only where they are so designated (or are able to be designated if not already), whereas in Scotland any route that meets certain conditions is rights of way in Scotland, defined as a right of way, and in addition, there is a general presumption of access to the countryside ("right to roam"). Private rights of way or easements also exist (see also Highways in England and Wales). Inner London Definitive maps of public rights of way have been compiled for all of England and Wales, as a result of the National Parks and Access to the Countryside Act 1949, except the 12 Inner London boroughs, which, along with the City of London, were not covered by the Act. Definitive maps exist for the Outer London bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal Seam
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit', and the above-ground structures are a 'pit head'. In Australia, "colliery" generally refers to an underground coal mine. Coal mining has had many developments in recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open-cut and longwall mines. Mining at this scale requires the use of draglines, trucks, conveyors, hydraulic jacks and shearers. The coal mining industry has a long history of significant negative environmental impacts on local ecosystems, health impacts on local communities and workers, and contributes heavily to th ...

South Wales Coalfield
The South Wales Coalfield ( cy, Maes glo De Cymru) extends across Pembrokeshire, Carmarthenshire, Swansea, Neath Port Talbot, Bridgend, Rhondda Cynon Taf, Merthyr Tydfil, Caerphilly, Blaenau Gwent and Torfaen. It is rich in coal deposits, especially in the South Wales Valleys. Description It comprises a fully exposed synclinorium with a varying thickness of coal measures (Upper Carboniferous/Pennsylvanian) with thick, workable seams in the lower parts and generally thinner and sparser seams in the upper parts, together with a development of sandstones (Pennant Sandstone). These sandstones have been much used in building construction (including the characteristic terraces of former miners' houses) and give rise to bleak uplands rising 300–600 metres above sea level between the steep-sided valleys in which most deep mines were developed. The coal generally increases in grade or "rank" from east to west, with bituminous coals in the east, and anthracite in the west, mostly to ...

Warwickshire Group
The Warwickshire Group is a lithostratigraphic unit of rock strata defined within the British Carboniferous system. Within the Pennine Basin it overlies (i.e. postdates) the Coal Measures Group and is deemed to be of late Westphalian and Stephanian age. In the South Wales Coalfield it consists of the Pennant Sandstone Formation and overlying Grovesend Formation. It contains the youngest Carboniferous rocks in Britain. The name Warwickshire Group is a relatively recent one, replacing a variety of earlier names for the succession of coal-barren red-beds such as Barren Coal Measures and Red Measures which overlie the productive coal measures. It is derived from the Warwickshire Coalfield The Warwickshire Coalfield extends between Warwick and Tamworth in the English Midlands. It is about from north to south and its width is around half that distance. Its western margin is defined by the 'Western Boundary Fault'. In the northeast ... where they achieve their thickest develop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caerphilly
Caerphilly (, ; cy, Caerffili, ) is a town and community in Wales. It is situated at the southern end of the Rhymney Valley. It is north of Cardiff and northwest of Newport. It is the largest town in Caerphilly County Borough, and lies within the historic borders of Glamorgan, on the border with Monmouthshire. At the 2011 Census, the town had a population of 41,402 while the wider Caerphilly Local Authority area has a population of 178,806. Toponym The name of the town in Welsh, , means "the fort () of Ffili". Despite lack of evidence, tradition states that a monastery was built by St Cenydd, a sixth-century Christian hermit from the Gower Peninsula, in the area. The Welsh cantref in the medieval period was known as Senghenydd. It is said that St Cenydd's son, St Ffili, built a fort in the area thus giving the town its name. Another explanation given for the toponym is that the town was named after the Anglo-Norman Marcher Lord, Philip de Braose. History The town's sit ...

Pennant Measures
The Pennant Measures is the traditional name for a sequence of sedimentary rocks of the South Wales Coalfield. They were also referred to as the Upper Coal Measures and assigned to the Westphalian 'C' and Westphalian 'D' stages of the Carboniferous Period. The Pennant Measures were divided into the Lower Pennant Measures and the Upper Pennant Measures, differing from the underlying Middle and Lower Coal Measures in being principally of sandstone units – known collectively as the Pennant Sandstone – with mudstone being the subsidiary rock type. Numerous coal seams occur within the Pennant Measures though they are less common than in the underlying Coal Measures.British Geological Survey 1:50,000 map sheet 231 'Merthyr Tydfil' & accompanying memoir. However recent reclassification of the sequence has resulted in the definition by the British Geological Survey of the Pennant Sandstone Formation as a sub-unit of the newly established Warwickshire Group. The formation is recognised ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
