Geology Of Wales
The geology of Wales is complex and varied; its study has been of considerable historical significance in the development of geology as a science. All geological periods from the Cryogenian (late Precambrian) to the Jurassic are represented at outcrop, whilst younger sedimentary rocks occur beneath the seas immediately off the Welsh coast. The effects of two mountain-building episodes have left their mark in the faulting and folding of much of the Palaeozoic rock sequence. Superficial deposits and landforms created during the present Quaternary period by water and ice are also plentiful and contribute to a remarkably diverse landscape of mountains, hills and coastal plains. Wales' modern character derives in substantial part from the exploitation of its diverse mineral wealth; slate in Snowdonia, coal in the South Wales Valleys and metal ores in Anglesey and mid Wales, to name but three. Wales' geology influences farming practices and building stone choices but also plannin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Wales Valleys
The South Wales Valleys () are a group of industrialised peri-urban valleys in South Wales. Most of the valleys run northsouth, roughly parallel to each other. Commonly referred to as "The Valleys" (), they stretch from Carmarthenshire in the west to Monmouthshire in the east; to the edge of the pastoral country of the Vale of Glamorgan and the coastal plain near the cities of Swansea, Cardiff, and Newport. History Until the mid-19th century, the South Wales valleys were sparsely inhabited. The industrialisation of the Valleys occurred in two phases. First, in the second half of the 18th century, the iron industry was established on the northern edge of the Valleys, mainly by English entrepreneurs. This made South Wales the most important part of Britain for ironmaking until the middle of the 19th century. Second, from 1850 until the outbreak of the First World War, the South Wales Coalfield was developed to supply steam coal and anthracite. The South Wales Valleys hosted B ...

Roderick Murchison
Sir Roderick Impey Murchison, 1st Baronet (19 February 1792 – 22 October 1871) was a Scottish geologist who served as director-general of the British Geological Survey from 1855 until his death in 1871. He is noted for investigating and describing the Silurian, Devonian and Permian systems. Early life and work Murchison was born at Tarradale House, Muir of Ord, Ross-shire, the son of Barbara and Kenneth Murchison. His wealthy father died in 1796, when Roderick was four years old, and he was sent to Durham School three years later and then to the Royal Military College, Great Marlow, to be trained for the army. In 1808, under Wellesley, he landed in Portugal, and was present at the actions of Roliça and Vimeiro in the Peninsular War as an ensign in the 36th Regt of Foot. Subsequently, under Sir John Moore, he took part in the retreat to Corunna and the final battle there. After eight years of service Murchison left the army and married Charlotte Hugonin (1788–1869 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neath
Neath (; ) is a market town and Community (Wales), community situated in the Neath Port Talbot, Neath Port Talbot County Borough, Wales. The town had a population of 50,658 in 2011. The community of the parish of Neath had a population of 19,258 in 2011. Historic counties of Wales, Historically in Glamorgan, the town is located on the River Neath, east-northeast of Swansea. Etymology The town's English name ultimately derives from "" the original Welsh name for the River Neath and is known to be Proto-Celtic language, Celtic or Pre-Celtic. A meaning of 'shining' or 'brilliant' has been suggested, as has a link to the older Indo-European root (simply meaning 'river'). As such, the town may share its etymology with the town of Stratton, Cornwall and the River Nidd in Northern England. History Roman fort The town is located at a ford (crossing), ford of the River Neath and its strategic situation is evident by a number of Celts, Celtic hill forts, surrounding the town. The Ro ...

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of '' Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before prin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Owen Of Henllys
George Owen of Henllys (1552 – 26 August 1613) was a Welsh antiquarian, author, and naturalist. Early life George Owen was the eldest son born to Elizabeth Herbert and William Owen in Henllys of the parish of Nevern, near Newport, Pembrokeshire. William Owen ( 1486–1574) was a successful Welsh lawyer who purchased the Lordship of Kemys. Following his father's death, he inherited the estate. Lordship of Kemys George Owen was educated in law at the Inns of Court in London. He spent considerable time fighting a series of lawsuits against family enemies in the county over ownership of manorial franchises. Wales historian During his life span he collected antiquarian information about Wales, including the heraldry, genealogy and historical buildings and structures. He also studied the topography of the county of Pembrokeshire and other parts of Wales. During his studies he performed observations of the geology of Wales, including the strata of limestone and coal. Although he ...

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of Clay mineral, clay minerals (hydrous aluminium phyllosilicates, e.g., Kaolinite, kaolin, aluminium, Al2Silicon, Si2Oxygen, O5(hydroxide, OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers (Lamination (geology), laminae) less than one centimeter in thickness. This property is called ''Fissility (geology), fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the narrower sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks in ...

Giraldus Cambrensis
Gerald of Wales (; ; ; ) was a Cambro-Norman priest and historian. As a royal clerk to the king and two archbishops, he travelled widely and wrote extensively. He studied and taught in France and visited Rome several times, meeting the Pope. He was nominated for several bishoprics but turned them down in the hope of becoming Bishop of St Davids, but was unsuccessful despite considerable support. His final post was as Archdeacon of Brecon, from which he retired to academic study for the remainder of his life. Much of his writing survives. Life Early life Born at Manorbier Castle in Pembrokeshire, Wales, Gerald was of mixed Norman and Welsh descent. Gerald was the youngest son of William Fitz Odo de Barry (or Barri), the common ancestor of the De Barry family of Barry, Glamorganshire, who subsequently invaded Ireland, a retainer of Arnulf de Montgomery and Gerald de Windsor, and one of the most powerful Anglo-Norman barons in Wales. His mother was Angharad FitzGerald, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of South Wales
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 plants from coal measures near Neath (Gibson late 17th century). The British geologists Adam Sedgwick and Roderick Murchison did fundamentally important work in South Wales on Old Red Sandstone and the underlying rocks. The first volume of memoirs (1846) published by the Geological Survey contained a conspectus of the geology of South Wales that set a template for all future work. Significant discoveries continue to be made. For instance, in Carmarthenshire, in the late 1970s, John Cope detected a small area of Precambrian and Cambrian rocks. Other parts of South Wales, however, have not se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Survey Map Of Great Britain, Sheet 2 South
Geology (). is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface and the processes that have shaped that structure. Geologists study the mineralogical composition of rocks in order to get insight into their history of formation. Geology determines the relative ages of rocks found at a given location; geochemistry (a branch of geology) determines their absolute ages. By combining various petrological, crystallographic, and paleontological tools, geologists are able to chronicle the geological history of the Earth as a whole. One aspect is to demonstrate the age of the Earth. Geology provides evidence for plate tectonics, the evolutionary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
