Benbulbin (), sometimes Benbulben or Ben Bulben, is a steep-sided and flat-topped mountain in County Sligo, Ireland. It is part of the Dartry Mountains, in an area sometimes called "William Butler Yeats, Yeats Country". Benbulbin, high, formed as a nunatak during the Last Glacial Period, last Ice Age. Benbulbin is a protected site, designated as a County Geology Site, County Geological Site by Sligo County Council. Etymology "Benbulbin", "Benbulben" and "Ben Bulben" are all anglicisations of the Irish name "Binn Ghulbain". "Binn" means "peak" or "mountain"; "ghulbain" may mean beak or jaw, or may refer to Conall Gulban, a son of Niall of the Nine Hostages, who was associated with the mountain. Geology Formation Benbulbin was shaped during the ice age, when Ireland was under glaciers. Originally it was a large plateau. Glaciers moving from the northeast to southwest shaped it into its present distinct formation. Rock composition Benbulbin, and the Dartry Mountains as a whol ...

Marilyn (hill)
This is a list of Marilyn hills and mountains in the United Kingdom, Republic of Ireland, Ireland and surrounding islands and Stack (geology), sea stacks. Lists of mountains and hills in the British Isles#Marilyns, Marilyns are defined as peaks with a topographic prominence, prominence of or more, regardless of height or any other merit (e.g. topographic isolation, as used in Lists of mountains and hills in the British Isles#Munros, Munros). Thus, Marilyns can be mountains, with a height above , or relatively small hills. there were 2,010 recorded Marilyns. Definition The Marilyn classification was created by Alan Dawson in his 1992 book ''The Relative Hills of Britain''. The name Marilyn was coined by Dawson as a punning contrast to the ''Munro'' classification of Scottish mountains above , but which has no explicit prominence threshold, being homophone, homophonous with (Marilyn) ''Marilyn Monroe, Monroe''. The list of Marilyns was extended to Ireland by Clem Clements. Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Donegal Bay
Donegal Bay () is an inlet (or bay) in the northwest of Ireland. Three Counties of Ireland, counties – County Donegal, Donegal to the north and west, County Leitrim, Leitrim and County Sligo, Sligo to the south – have shorelines on the bay, which is bounded on the west by the Atlantic Ocean. The town of Donegal (town), Donegal and the River Eske lie at the head of the bay. Donegal Bay is Ireland's largest bay, and also contains Ulster's highest (and Ireland, Ireland's's second-highest) sea cliffs at Slieve League, which tower 1972 ft (601 m) above sea level. Donegal Bay's beaches have some of Europe's finest surfing, caused by a combination by a direct west-facing location and the funnel-shape of Donegal Bay (the westerlies of the Atlantic Ocean get funnelled into a relatively small area, which increases the size of the swell). Rossnowlagh and Bundoran are recognised by the European surfing community as among Ireland's finest surf beaches with good facili ...

Atlantic
The Atlantic Ocean is the second largest of the world's five oceanic divisions, with an area of about . It covers approximately 17% of Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an age of exploration and colonization of the Americas by European powers, most notably Portugal, Spain, France, and the United Kingdom. From the 16th to 19th centuries, the Atlantic Ocean was the center of both an eponymou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RTÉ
(; ; RTÉThe É in RTÉ is pronounced as an English E () and not an Irish É ()) is an Irish public service broadcaster. It both produces and broadcasts programmes on television, radio and online. The radio service began on 1 January 1926, while regular television broadcasts began on 31 December 1961, making it one of the oldest continuously operating public service broadcasters in the world. It is headquartered in Donnybrook in Dublin, with offices across different parts of Ireland. RTÉ is a statutory body, overseen by a board appointed by the Government of Ireland, with general management in the hands of a committee of senior managers, currently an interim leadership team, headed by the Director General. RTÉ is regulated by Coimisiún na Meán. It is financed by the television licence fee and through advertising, with some of its services funded solely by advertising, while others are funded solely by the licence fee.

Baryte
Baryte, barite or barytes ( or ) is a mineral consisting of barium sulfate (Ba S O4). Baryte is generally white or colorless, and is the main source of the element barium. The ''baryte group'' consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid solution . Names and history The radiating form, sometimes referred to as ''Bologna Stone'', attained some notoriety among alchemists for specimens found in the 17th century near Bologna by Vincenzo Casciarolo. These became phosphorescent upon being calcined. Carl Scheele determined that baryte contained a new element in 1774, but could not isolate barium, only barium oxide. Johan Gottlieb Gahn also isolated barium oxide two years later in similar studies. Barium was first isolated by electrolysis of molten barium salts in 1808 by Sir Humphry Davy in England. The American Petroleum Institute specification API 13/ISO 13500, which governs '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scree
Scree is a collection of broken rock fragments at the base of a cliff or other steep rocky mass that has accumulated through periodic rockfall. Landforms associated with these materials are often called talus deposits. The term ''scree'' is applied both to an unstable steep mountain slope composed of rock fragments and other debris, and to the mixture of rock fragments and debris itself. It is loosely synonymous with talus, material that accumulates at the base of a projecting mass of rock, or talus slope, a landform composed of talus. The term ''scree'' is sometimes used more broadly for any sheet of loose rock fragments mantling a slope, while ''talus'' is used more narrowly for material that accumulates at the base of a cliff or other rocky slope from which it has obviously eroded. Scree is formed by rockfall, which distinguishes it from colluvium. Colluvium is rock fragments or soil deposited by rainwash, sheetwash, or slow downhill creep, usually at the base of gentle ...

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 ...
