Castle Hill, Kerry
Slieve Mish Mountains (), is a predominantly sandstone mountain range at the eastern end of the Dingle Peninsula in County Kerry, Ireland. Stretching , from the first major peak of Barnanageehy outside of Tralee in the east, to Cnoc na Stuaice in near Central Dingle in the west, the range has over 17 material peaks (e.g. height above 100 m), with the core of the mountain range based around the massif of its highest peak, Baurtregaum, and its deep glacial valleys of Derrymore Glen and Curraheen Glen. Naming The Irish language term "Sliabh" denotes a mountain, however, the precise meaning of "Mis" has not been validated. Irish academic Paul Tempan notes that it could be related to Slemish mountain in County Antrim, where the term "Mis" is from a female name, and thus translates as "the mountains of Mis". Geology Like many of the mountain ranges in County Kerry, such as the MacGillycuddy Reeks in the Iveragh Peninsula, the Slieve Mish Mountains are composed predominantly of ...

Irish Language
Irish (Standard Irish: ), also known as Irish Gaelic or simply Gaelic ( ), is a Celtic language of the Indo-European language family. It is a member of the Goidelic languages of the Insular Celtic sub branch of the family and is indigenous language, indigenous to the island of Ireland. It was the majority of the population's first language until the 19th century, when English (language), English gradually became dominant, particularly in the last decades of the century, in what is sometimes characterised as a result of linguistic imperialism. Today, Irish is still commonly spoken as a first language in Ireland's Gaeltacht regions, in which 2% of Ireland's population lived in 2022. The total number of people (aged 3 and over) in Ireland who declared they could speak Irish in April 2022 was 1,873,997, representing 40% of respondents, but of these, 472,887 said they never spoke it and a further 551,993 said they only spoke it within the education system.

Conglomerate (geology)
Conglomerate () is a sedimentary rock made up of rounded gravel-sized pieces of rock surrounded by finer-grained sediments (such as sand, silt, or clay). The larger fragments within conglomerate are called clasts, while the finer sediment surrounding the clasts is called the matrix. The clasts and matrix are typically cemented by calcium carbonate, iron oxide, silica, or hardened clay. Conglomerates form when rounded gravels deposited by water or glaciers become solidified and cemented by pressure over time. They can be found in sedimentary rock sequences of all ages but probably make up less than 1 percent by weight of all sedimentary rocks. They are closely related to sandstones in origin, and exhibit many of the same types of sedimentary structures, such as tabular and trough cross-bedding and graded bedding.Boggs, S.

Inishnabro
Inishnabro () is one of the Blasket Islands of County Kerry in Ireland. Geography Inishnabro is separated from Inishvickillane by a narrow sound (about 200 metres), and rises to 229 metres, and has an area of 49.15 hectares. Spaceport proposal In 1973, an American scientist, Gary Hudson (engineer), Gary Hudson, approached the IDA Ireland, Industrial Development Authority and then the Irish Consul General in Chicago, Sean Farrell, to propose using Inishnabro as the launching site for a new commercial space shuttle. Hudson said he represented a group including British astronomer Fred Hoyle, an American astronaut who had walked on the Moon, and others. In a memorandum to the Irish Department of Foreign Affairs and Trade (Ireland), Department of Foreign Affairs, Farrell wrote that his initial reaction was "one bordering on disbelief" but then concluded that Hudson was "genuine enough". Department officials, however, concluded that "Whatever his objective may be it is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fault (geology)
In geology, a fault is a Fracture (geology), planar fracture or discontinuity in a volume of Rock (geology), rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust (geology), crust result from the action of Plate tectonics, plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction, subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the Plane (geometry), plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geological maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone ...

Unconformable
An unconformity is a buried erosional or non-depositional surface separating two rock masses or strata of different ages, indicating that sediment deposition was not continuous. In general, the older layer was exposed to erosion for an interval of time before deposition of the younger layer, but the term is used to describe any break in the sedimentary geologic record. The significance of angular unconformity (see below) was shown by James Hutton, who found examples of Hutton's Unconformity at Jedburgh in 1787 and at Siccar Point in Berwickshire in 1788, both in Scotland. The rocks above an unconformity are younger than the rocks beneath (unless the sequence has been overturned). An unconformity represents time during which no sediments were preserved in a region or were subsequently eroded before the next deposition. The local record for that time interval is missing and geologists must use other clues to discover that part of the geologic history of that area. The interval o ...

Facies
In geology, a facies ( , ; same pronunciation and spelling in the plural) is a body of rock with distinctive characteristics. The characteristics can be any observable attribute of rocks (such as their overall appearance, composition, or condition of formation) and the changes that may occur in those attributes over a geographic area. A facies encompasses all the characteristics of a rock including its chemical, physical, and biological features that distinguish it from adjacent rock. The term "facies" was introduced by the Swiss geologist Amanz Gressly in 1838 and was part of his significant contribution to the foundations of modern stratigraphy, which replaced the earlier notions of '' Neptunism''. Walther's law Walther's law of facies, or simply Walther's law, named after the geologist Johannes Walther, states that the vertical succession of facies reflects lateral changes in environment. Conversely, it states that when a depositional environment "migrates" laterally, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silurian
The Silurian ( ) is a geologic period and system spanning 23.5 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the third and shortest period of the Paleozoic Era, and the third of twelve periods of the Phanerozoic Eon. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods ( myriapods, arachnids and hexapods) ...

Mount Brandon
Mount Brandon or Brandon (), at , is one of the ten highest peaks in Ireland, being the 8th–highest peak in Ireland on the Arderin list, and the 9th–highest on the Vandeleur-Lynam list. Brandon is the highest Irish mountain outside the MacGillycuddy's Reeks range and has the greatest prominence of any Irish peak except Carrauntoohil, Ireland's highest mountain. Mount Brandon is at the centre of a long high ridge called the Brandon Group range of mountains in the Dingle Peninsula in County Kerry. The ridge contains seven other major peaks (i.e. above 2,000 ft in height); one is the similarly named Brandon Peak (840 metres). The positioning and dimensions of the Brandon Group ridge have made it the scene of several air accidents over the years. The mountain, and range, is named after Saint Brendan, and is the end of a Christian pilgrimage trail known as ''Cosán na Naomh''. It is also well regarded for hill walking with routes such as the 4–5-hour ''Faha Route'' (also call ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Parks And Wildlife Service (Ireland)
The National Parks and Wildlife Service () manages the Irish State's nature conservation responsibilities. As well as managing the national parks, the activities of the NPWS include the designation and protection of Natural Heritage Areas, Special Areas of Conservation and Special Protection Areas. History The Service was established as part of the Department of the Environment, Heritage and Local Government after the abolition of Dúchas in 2003. Dúchas's responsibilities had included the management of Ireland's six national parks and wildlife. In 2011 built and natural heritage came into the remit of the Department of Arts, Heritage and the Gaeltacht as part of a reorganisation of Irish departments.

Metasediments
In geology, metasedimentary rock is a type of metamorphic rock. Such a rock was first formed through the deposition and solidification of sediment Sediment is a solid material that is transported to a new location where it is deposited. It occurs naturally and, through the processes of weathering and erosion, is broken down and subsequently sediment transport, transported by the action of .... Then, the rock was buried underneath subsequent rock and was subjected to high pressures and temperatures, causing the rock to recrystallize. The overall composition of a metasedimentary rock can be used to identify the original sedimentary rock, even where they have been subject to high-grade metamorphism and intense deformation.

Old Red Sandstone
Old Red Sandstone, abbreviated ORS, is an assemblage of rocks in the North Atlantic region largely of Devonian age. It extends in the east across Great Britain, Ireland and Norway, and in the west along the eastern seaboard of North America. It also extends northwards into Greenland and Svalbard. These areas were a part of the paleocontinent of Euramerica (Laurussia). In Britain it is a lithostratigraphic unit (a sequence of rock strata) to which stratigraphers accord supergroup status and which is of considerable importance to early paleontology. The presence of ''Old'' in the name is to distinguish the sequence from the younger New Red Sandstone which also occurs widely throughout Britain. Sedimentology The Old Red Sandstone describes a group of sedimentary rocks deposited in a variety of environments in the late Silurian, through the Devonian and into the earliest part of the Carboniferous. The body of rock, or facies, is dominated by terrigenous deposits and co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
