Flintshire Coalfield
The Flintshire Coalfield in north-east Wales is one of the smaller Great Britain, British coalfields. It is in the county of Flintshire and extends from the Point of Ayr in the north, along the Dee Estuary through Connah's Quay to Caergwrle in the south. A small part extends onto the Wirral Peninsula, Wirral i.e. England, English coast of the estuary at Neston, Cheshire which was the site of a coalmine for a period. The coal-bearing stratum, strata continue southwards of Caergwrle as the Denbighshire Coalfield. Together the two coalfields are known as the North Wales Coalfield. Geology Several coal seams are named in the sequence. Some seams are absent in the northern part of the coalfield and are labelled as (S) whilst the others occur across the coalfield as a whole. The Chwarelau Seam which appears only in the north actually occurs within the underlying Millstone Grit sequence rather than the Coal Measures proper. The seams are listed stratigraphically with the uppermost (young ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Stratum
In geology and related fields, a stratum ( : strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either '' bedding surfaces'' or ''bedding planes''.Salvador, A. ed., 1994. ''International stratigraphic guide: a guide to stratigraphic classification, terminology, and procedure. 2nd ed.'' Boulder, Colorado, The Geological Society of America, Inc., 215 pp. . Prior to the publication of the International Stratigraphic Guide, older publications have defined a stratum as either being either equivalent to a single bed or composed of a number of beds; as a layer greater than 1 cm in thickness and constituting a part of a bed; or a general term that includes both ''bed'' and ''lamina''.Neuendorf, K.K.E., Mehl, Jr., J.P., and Jackson, J.A. , eds., 2005.

Geography Of Flintshire
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Coal Mining In Wales
The coal industry in Wales played an important role in the Industrial Revolution. Coal mining in Wales expanded in the 18th century to provide fuel for the blast furnaces of the iron and copper industries that were expanding in southern Wales. The industry had reached large proportions by the end of that century, and then further expanded to supply steam-coal for the steam vessels that were beginning to trade around the world. The Cardiff Coal Exchange set the world price for steam-coal and Cardiff became a major coal-exporting port. The South Wales Coalfield was at its peak in 1913 and was one of the largest coalfields in the world. It remained the largest coalfield in Britain until 1925. The supply of coal dwindled, and pits closed in spite of a UK-wide strike against closures. Aberpergwm Colliery is the last deep mine in Wales. The South Wales Coalfield was not the only coal mining area of the country. There was a sizeable industry in Flintshire and Denbighshire in north ...

Gwespyr Sandstone Formation
Gwespyr is a village in Flintshire on the north coast of Wales in the community of Llanasa. Gwespyr had a population of 289 people in the United Kingdom 2001 census. It overlooks Point of Ayr on the west side of the River Dee estuary and its sandy beaches with dunes. The hills of the Clwydian Range behind the village form the eastern boundary of the Vale of Clwyd. Gwespyr also looks respectively Welsh but is an alien name. It represents Old English for 'West-bury' which came to be interpreted as the 'west fort' meaning the westernmost fort in Mercia. Originally, it is thought to have been a strategic Mercian lookout which was reduced in importance with the development of a fortified Rhuddlan. Gwespyr stone has been quarried in quantity from Roman times and shipped to the rest of the UK and abroad. "Gwespyr Stone" was commercially successful for its grain, colour, and quality of cutting and shaping. It was used for many buildings around Gwespyr, and was also used to build the an ...

Pennine Coal Measures Group
The Pennine Coal Measures Group is a lithostratigraphical term referring to the coal-bearing succession of rock strata which occur in the United Kingdom within the Westphalian Stage of the Carboniferous Period. In formal use, the term replaces the Coal Measures Group as applied to the succession of coal-bearing strata within the Pennine Basin which includes all of the coalfields of northern England and the English Midlands. It includes the largely concealed Canonbie Coalfield of southern Scotland and the coalfields of northeast Wales and the minor Anglesey coalfield. The sequence consists in the main of mudstones and siltstones together with numerous sandstones, the more significant ones of which are individually named. Some are laterally extensive, others are more restricted in their range. There are numerous coal seams, again with some being more laterally continuous than others. Those which were economically valuable were named though any individual seam may have attracted di ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Coal Measures
In lithostratigraphy, the coal measures are the coal-bearing part of the Upper Carboniferous System. In the United Kingdom, the Coal Measures Group consists of the Upper Coal Measures Formation, the Middle Coal Measures Formation and the Lower Coal Measures Formation. The group records the deposition of fluvio-deltaic sediments which consists mainly of clastic rocks (claystones, shales, siltstones, sandstones, conglomerates) interstratified with the beds of coal. In most places, the coal measures are underlain by coarser clastic sequences known as Millstone Grit, of Namurian age. The top of the coal measures may be marked by an unconformity, the overlying rocks being Permian or later in age. In some parts of Britain, however, the coal measures grade up into mainly coal-barren red beds of late Westphalian and possibly Stephanian age. Within the Pennine Basin these barren measures are now referred to as the Warwickshire Group, from the district where they achieve their thickest d ...

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 ...

North Wales Coalfield
The North Wales Coalfield comprises the Flintshire Coalfield in the north and the Denbighshire Coalfield in the south. It extends from Point of Ayr in the north, through the Wrexham area to Oswestry in Shropshire in the south. A much smaller area on Anglesey where coal was formerly mined is not usually considered to form a part of the coalfield, although it is geographically in the North Wales region. History In north Wales, the Flintshire manors of Ewloe, Hopedale, and Mostyn and the Denbighshire manor of Brymbo were recorded as making profits from trading coal during the 14th and 15th centuries. By 1593, coal was exported from ports on the Dee estuary. Trade developed swiftly and by 1616, the principal collieries were at Bagillt, Englefield, Leaderbrook, Mostyn, Uphfytton and Wepre. Most were horizontal adits or shallow bell pits, although a few were sufficiently large to have accumulations of water and ventilation problems. In the Denbighshire Coalfield, the areas of ...

Denbighshire Coalfield
The Denbighshire Coalfield in the historic county of Denbighshire in north-east Wales is one of the smaller British coalfields. It extends from near Caergwrle in the north, southwards through Wrexham, Ruabon and Rhosllannerchrugog to Chirk in the south. A small part extends into Shropshire around Oswestry. Beyond Caergwrle the coal-bearing strata continue northwards as the Flintshire Coalfield. Together the two coalfields are known as the North Wales Coalfield. History The shallower parts of the Denbighshire Coalfield were worked extensively in the early nineteenth century, most of the coal being used in the iron industry. In the mid-nineteenth century, much deeper pits were established and a network of railways was built in the Wrexham area to transport the coal. A report on the North Wales Coalfield in the 1950s found that the reserves of coal were running low and that in the Denbighshire Coalfield, the geology of the coal-bearing strata dipped rapidly rendering it unlikel ...
