Iapetus Suture
The Iapetus Suture is one of several major Fault (geology), geological faults caused by the collision of several ancient land masses forming a suture (geology), suture. It represents in part the remains of what was once the Iapetus Ocean. Iapetus was the father of Atlas (mythology), Atlas in Greek mythology, making his an appropriate name for what used to be called the 'Proto-Atlantic Ocean'. When the Atlantic Ocean opened, in the Cretaceous period, it took a slightly different line from that of the Iapetus suture, with some originally Laurentian rocks being left behind in north-west Europe and other, Avalonian, rocks remaining as part of Newfoundland. Background The Iapetus Ocean was an ancient ocean which existed in the Southern Hemisphere approximately 600 million years ago and was bordered by several paleocontinents: Laurentia, Ganderia, Carolinia, Avalonia, and Baltica. During a series of geological events, the Salinic orogeny and Caledonian progeny, all three land masses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caledonides EN
The Caledonian orogeny was a orogeny, mountain-building cycle recorded in the northern parts of the British Isles, the Scandinavian Caledonides, Svalbard, East Greenland Orogen, eastern Greenland and parts of north-central Europe. The Caledonian orogeny encompasses events that occurred from the Ordovician to Early Devonian, roughly 490–390 million years ago (Megaannum, Ma). It was caused by the closure of the Iapetus Ocean when the Laurentia and Baltica continents and the Avalonia microcontinent collided. The orogeny is named for Caledonia, the Latin name for Scotland. The term was first used in 1885 by Austrian geologist Eduard Suess for an episode of mountain building in northern Europe that predated the Devonian period (geology), period. Geologists like Émile Haug and Hans Stille saw the Caledonian event as one of several episodic phases of mountain building that had occurred during History of Earth, Earth's history.McKerrow ''et al.''

River Shannon
The River Shannon ( or archaic ') is the major river on the island of Ireland, and at in length, is the longest river in the British Isles. It drains the Shannon River Basin, which has an area of , – approximately one fifth of the area of Ireland. Known as an important waterway since antiquity, the Shannon first appeared in maps by the Graeco-Egyptian geographer Ptolemy ( 100 – 170 AD). The river flows generally southwards from the Shannon Pot in County Cavan before turning west and emptying into the Atlantic Ocean through the long Shannon Estuary. Limerick city stands at the point where the river water meets the sea water of the estuary. The Shannon is tidal east of Limerick as far as the base of the Ardnacrusha dam. The Shannon divides the west of Ireland (principally the province of Connacht) from the east and south (Leinster and most of Munster; County Clare, being west of the Shannon but part of the province of Munster, is the major exception.) The river rep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kilkee Folds
Kilkee () is a coastal town in County Clare, Ireland. It is located in the parish of Kilkee ''(formerly Kilfearagh)''. Kilkee is midway between Kilrush and Doonbeg on the N67 road and is a popular seaside resort. The horseshoe bay is protected from the Atlantic Ocean by the Duggerna Reef. History In the early 19th century, Kilkee was a small fishing village. Around the 1820s, a paddle steamer service from Limerick to Kilrush made Kilkee more accessible as a tourist destination, particularly for the Anglo-Irish aristocracy. Catty Fitzgerald opened the first hotel, which operated for 40 years. By the 1830s, two more hotels opened in Kilkee. Along with these, three churches were built, a Roman Catholic church in 1831, a Protestant church in 1843, and a Methodist church in 1900. Descriptions of Kilkee during the Irish Famine can be found in John Manners’s travel narrative ''Notes of an Irish Tour, in 1846'' and Sydney Godolphin Osborne's ''Gleanings in the West of Ireland ...

Red Indian Lake
Beothuk Lake, formerly Red Indian Lake, is located in the interior of central Newfoundland in the province of Newfoundland and Labrador, Canada. The lake drains into the Exploits River which flows through the interior of Newfoundland and exits into the Atlantic Ocean through the Bay of Exploits. Lloyds River, the Victoria River and Star River feed into the lake. History The Beothuk inhabited several campsites on the shore of the lake. An expedition into the interior by John Cartwright and brother George Cartwright in search of the Beothuk found only abandoned campsites. At the time of their discovery of the lake they named it ''Lieutenant's Lake.'' In January 1811, an expedition led by David Buchan travelled up the Exploits River in an attempt to establish friendly relations with the Beothuk; Buchan found them, but the encounter went badly and resulted in the deaths of two marines. John Peyton Jr. led another expedition to the lake in 1819 which also ended in tragedy; the exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newfoundland (island)
Newfoundland ( , ; , ) is a large island within the Canadian province of Newfoundland and Labrador. It is situated off the eastern coast of the Northern America, North American mainland and the geographical region of Labrador. The island contains 29 percent of the province's land area, but is home to over 90% of the province's population, with about 60% of the province's population located on the small southeastern Avalon peninsula. The island is separated from the Labrador Peninsula by the Strait of Belle Isle and from Cape Breton Island by the Cabot Strait. It blocks the mouth of the Saint Lawrence River, creating the Gulf of Saint Lawrence, the world's largest estuary. Newfoundland's nearest neighbour is the French overseas collectivity of Saint Pierre and Miquelon.

Baie Verte, Newfoundland And Labrador
Baie Verte ( 2021 Population 1,311) is a town located on the north coast of the island portion of the Canadian province of Newfoundland and Labrador on the Baie Verte Peninsula. The French named the area for its greenness, "green bay." Geography Baie Verte is one of 42 communities that make up the Emerald Zone which is located in the North Central portion of Newfoundland. Baie Verte dates to the late 19th century, but remained a small village until the discovery of asbestos and other ore bodies of copper, lead, zinc and gold in the mid-1950s when the town underwent major expansion. Bowering Brother's steamers called in the area in the 1950s to transport the ore found here. It became a town in 1968. The major Baie Verte fault line starts here and runs from here to Long Island Sound by way of Vermont.The Chronicle, September 8, 2008, page 22, "Geologist give talk about Lowell's geologic history" Climate History The Baie Verte asbestos deposit was discovered in 1955, and Adv ...

Ordovician
The Ordovician ( ) is a geologic period and System (geology), system, the second of six periods of the Paleozoic Era (geology), Era, and the second of twelve periods of the Phanerozoic Eon (geology), Eon. The Ordovician spans 41.6 million years from the end of the Cambrian Period Megaannum, Ma (million years ago) to the start of the Silurian Period Ma. The Ordovician, named after the Celtic Britons, Welsh tribe of the Ordovices, was defined by Charles Lapworth in 1879 to resolve a dispute between followers of Adam Sedgwick and Roderick Murchison, who were placing the same Rock (geology), rock beds in North Wales in the Cambrian and Silurian systems, respectively. Lapworth recognized that the fossil fauna in the disputed Stratum, strata were different from those of either the Cambrian or the Silurian systems, and placed them in a system of their own. The Ordovician received international approval in 1960 (forty years after Lapworth's death), when it was adopted as an official per ...

Back-arc Basin
A back-arc basin is a type of geologic Structural basin, basin, found at some convergent boundary, convergent plate boundaries. Presently all back-arc basins are submarine features associated with island arcs and subduction zones, with many found in the western Pacific Ocean. Most of them result from Tension (physics), tensional forces, caused by a process known as Oceanic trench#Trench rollback, oceanic trench rollback, where a subduction zone moves towards the subducting plate. Back-arc basins were initially an unexpected phenomenon in plate tectonics, as convergent boundaries were expected to universally be zones of compression. However, in 1970, Dan Karig published a model of back-arc basins consistent with plate tectonics. Structural characteristics Back-arc basins are typically very long and relatively narrow, often thousands of kilometers long while only being a few hundred kilometers wide at most. For back-arc extension to form, a subduction zone is required, but not a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
