Holkerian
The Holkerian is a sub-stage of the Viséan stage of the International Commission on Stratigraphy (ICS) geological timescale. It is one of five sub-stages commonly used in the Viséan stage within stratigraphy by British, Irish and other geologists outside the US and Asia. As part of the Viséan, Holkerian rocks were formed about 339 to 335 million years ago, in the Early Carboniferous subperiod. Rock formations laid down in this time were frequently different types of fossiliferous limestone. The material for all these rocks was laid down in warm, sub-tropical marine conditions of the time when north-western Europe was close to the equator. Definition In 1976, the Viséan and Tournaisian were divided into six stages (now substages) by George et al. (the substages underwent some redefinition by Waters et al. in 2011). The Holkerian base was defined at the boundary between the Dalton Beds and the Park Limestone Formation at Barker Scar, Cumbria. The boundary was supposed to be below ...

Hunts Bay Oolite
Hunts Bay Oolite is an oolitic Carboniferous limestone geological formation found in the south Wales region. It is named after Hunts Bay on the Gower peninsula, south-south west of Bishopston, where a significant amount of the limestone forms the cliffs there. Hunts Bay Oolite is a sub-group of the Pembroke Limestone Group which itself is part of the Carboniferous Limestone Supergroup. Oolite means 'egg stone': very small grains (up to 2mm) form by accumulating precipitated minerals, usually calcium carbonate. These ooids, created in a warm, tropical environment, are the precursors to the limestone. The Hunts Bay Oolite extends from Pembroke in the West to Monmouth and Chepstow in the East and northwards into the Dowlais Limestone Formation around Merthyr Tydfil. Fossils, such as brachiopods and crinoids associated with a shallow sea environment, can be found in the rock. East of the South Wales Coalfield and in the south east the rock is increasingly dolomitised (wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viséan
The Visean, Viséan or Visian is an age in the ICS geologic timescale or a stage in the stratigraphic column. It is the second stage of the Mississippian, the lower subsystem of the Carboniferous. The Visean lasted from to Ma. It follows the Tournaisian age/stage and is followed by the Serpukhovian age/stage. Name and definitions The Viséan Stage was introduced by Belgian geologist André Dumont in 1832. Dumont named this stage after the city of Visé in Belgium's Liège Province. Before being used as an international stage, the Visean Stage was part of the (West) European regional geologic time scale, in which it followed the Tournaisian Stage and is followed by the Namurian Stage. In the North American regional scale, the Visean Stage correlates with the upper Osagean, the Meramecian and lower Chesterian stages. In the Chinese regional time scale, it correlates with the lower and middle Tatangian series.; 2006: ''Global time scale and regional stratigraphic reference sca ...

Scaleber Force
Scaleber Force (also known as Scaleber Foss and Scaleber Waterfall), is a high waterfall on Stockdale Beck, later the Long Preston Beck, that feeds into the River Ribble between Settle and Long Preston in North Yorkshire, England. The waterfall is the result of geological faulting (part of the South Craven Fault) and is a popular tourist attraction. Toponymy The waterfall is written variously as Scaleber Waterfall, Scaleber Force and Scaleber Foss. Though Foss is an Old Norse word meaning waterfall, from which Force is derived, the two are interchangeable in some sources. However, Ordnance Survey mapping shows it as Scaleber Force. The local pronunciation of Scaleber is ''Scallyber'', though ''Scale-ber'' is often heard. Geology Scaleber Force lies on the South Craven Fault, and the action of the water has eroded the soft limestone into a deep gorge, exposing limestone boulder beds at the top of the waterfall. The limestone at Scaleber Force is either Late Arundian stage, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holker Hall
Holker Hall (pronounced Hooker by some) is a privately owned country house located about 2 km to the southwest of the village of Cartmel in the ceremonial county of Cumbria and historic county of Lancashire, England. It is "the grandest uildingof its date in Lancashire ...by the best architects then living in the county." The building dates from the 16th century, with alterations, additions, and rebuilding in the 18th and 19th centuries. The 19th century rebuilding was by George Webster in Jacobean Revival style and subsequent renovations were by E. G. Paley. Hubert Austin had a joint practice with Paley by the 1870s and they both rebuilt the west wing after it was destroyed by a major fire in 1871, only a decade after Paley's previous work on the structure. The fire also destroyed a number of notable artworks. Holker Hall is Paley and Austin's "most important country house commission." The architectural historian Nikolaus Pevsner expressed the opinio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
