Glenmacnass Waterfall
Glenmacnass Waterfall () is an 80-metre high waterfall situated at the head of the Glenmacnass Valley in the Wicklow Mountains in Ireland. The Glenmacnass Waterfall is a popular tourist destination and scenic viewpoint area in the Wicklow Mountains. The Waterfall is bounded to the west by Tonelagee, and to the east by Scarr mountain. The entire Glenmacnass Valley can be accessed by the R115 road (also called the ''Military Road''), which connects the Sally Gap in the north, to the village of Laragh in the south. Geography The Glenmacnass River begins high up on the southeast slopes of Mullaghcleevaun , with smaller tributaries flowing in from the eastern slopes of Tonelagee ; the river then reaches the top of the waterfall at an elevation of above sea-level, where it falls down the waterfall in 3 staggered drops to an elevation of above sea-level, where it reaches the Glenmacnass Valley floor. The river continues through the U-shaped valley until it joins the Avonmore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wicklow Mountains
The Wicklow Mountains (, archaic: ''Cualu'') form the largest continuous upland area in the Republic of Ireland. They occupy the whole centre of County Wicklow and stretch outside its borders into the counties of Dublin, Wexford and Carlow. Where the mountains extend into County Dublin, they are known locally as the Dublin Mountains (''Sléibhte Bhaile Átha Cliath''). The highest peak is Lugnaquilla at . The mountains are primarily composed of granite surrounded by an envelope of mica-schist and much older rocks such as quartzite. They were pushed up during the Caledonian orogeny at the start of the Devonian period and form part of the Leinster Chain, the largest continuous area of granite in Ireland and Britain. The mountains owe much of their present topography to the effects of the last ice age, which deepened the valleys and created corrie and ribbon lakes. Copper and lead have been the main metals mined in the mountains and a brief gold rush occurred in the 18th c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quaternary Glaciation
The Quaternary glaciation, also known as the Pleistocene glaciation, is an alternating series of glacial and interglacial periods during the Quaternary period that began 2.58 Ma (million years ago) and is ongoing. Although geologists describe this entire period up to the present as an "ice age", in popular culture this term usually refers to the most recent glacial period, or to the Pleistocene epoch in general. Since Earth still has polar ice sheets, geologists consider the Quaternary glaciation to be ongoing, though currently in an interglacial period. During the Quaternary glaciation, ice sheets appeared, expanding during glacial periods and contracting during interglacial periods. Since the end of the last glacial period, only the Antarctic and Greenland ice sheets have survived, with other sheets formed during glacial periods, such as the Laurentide Ice Sheet, having completely melted. The major effects of the Quaternary glaciation have been the continental erosio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torc Waterfall
Torc Waterfall () is a high, long cascade waterfall formed by the Owengarriff River as it drains from the '' Devil's Punchbowl'' corrie lake at Mangerton Mountain. The waterfall, which lies at the base of Torc Mountain, in the Killarney National Park, is from Killarney in County Kerry, Ireland. The waterfall is a popular site on the Ring of Kerry and the Kerry Way tours. Naming The word Torc is from the Irish translation of a "wild boar", and the area is associated with legends involving wild boars. One legend is of a man who was cursed by the Devil to spend each night transformed into a wild boar, but when his secret was revealed by a local farmer, he burst into flames and disappeared into the nearby ''Devils Punchbowl'' on Mangerton Mountain from which the Owengarriff River emerged to hide the entrance to his cave beneath the Torc Waterfall. There is also the story of how the legendary Irish warrior, Fionn MacCumhaill, killed a magical boar on Torc mountain with his g ...

Powerscourt Estate
Powerscourt Estate ( ga, Eastát Chúirt an Phaoraigh), located in Enniskerry, County Wicklow, Ireland, is a large country estate which is noted for its house and landscaped gardens, today occupying . The house, originally a 13th-century castle, was extensively altered during the 18th century by German architect Richard Cassels, starting in 1731 and finishing in 1741. A fire in 1974 left the house lying as a shell until it was renovated in 1996. The Wingfield family had long coveted the lands of Phelim O'Toole of Powerscourt (d. 1603), seeking to draw Phelim O'Toole into an act of rebellion, the penalty for which was forfeiture. The feud climaxed on 14 May 1603 when the Wingfields murdered Phelim in the place known as the Killing Hollow near Powerscourt, despite the fact that Phelim's grandson and heir Turlough son of Phelim's son (d. 1616) remained in occupation of Powerscourt. King James I of England (d. 1625) on 27 October 1603 granted a lease of the manor of Powerscourt f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powerscourt Waterfall
Powerscourt Waterfall ( ga, Eas Chonaill) is the second highest waterfall in Ireland at high, it is located at the base of the Glensoulan Valley on the River Dargle near Enniskerry, County Wicklow. Powerscourt is overlooked by the peaks of Djouce () and Maulin (), and flows continuously all year in a horsetail-fan pattern. The waterfall is part of the Powerscourt Estate, which is open to the public for an entrance fee. Geography Powerscourt Waterfall, known in Irish as ''Eas Chonaill'', lies at the base of the Glensoulan valley, a hanging valley, through which the River Dargle flows from its source on the southern slopes of Tonduff mountain, eventually falling into the steep corrie in which the waterfall lies. Several mountains surround the upper section of the Glensoulan valley in a "horseshoe-shape", being: Maulin , Tonduff , War Hill , and Djouce . The waterfall is bounded by Crone Woods on its northern section. Geology Geological Survey of Ireland (GSI) regard the w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Palaeozoic
The Paleozoic (or Palaeozoic) Era is the earliest of three geologic eras of the Phanerozoic Eon. The name ''Paleozoic'' ( ;) was coined by the British geologist Adam Sedgwick in 1838 by combining the Greek words ''palaiós'' (, "old") and ''zōḗ'' (), "life", meaning "ancient life" ). It is the longest of the Phanerozoic eras, lasting from , and is subdivided into six geologic periods (from oldest to youngest): # Cambrian # Ordovician # Silurian # Devonian # Carboniferous # Permian The Paleozoic comes after the Neoproterozoic Era of the Proterozoic Eon and is followed by the Mesozoic Era. The Paleozoic was a time of dramatic geological, climatic, and evolutionary change. The Cambrian witnessed the most rapid and widespread diversification of life in Earth's history, known as the Cambrian explosion, in which most modern phyla first appeared. Arthropods, molluscs, fish, amphibians, reptiles, and synapsids all evolved during the Paleozoic. Life began in the ocean but ...

Schist
Schist ( ) is a medium-grained metamorphic rock showing pronounced schistosity. This means that the rock is composed of mineral grains easily seen with a low-power hand lens, oriented in such a way that the rock is easily split into thin flakes or plates. This texture reflects a high content of platy minerals, such as micas, talc, chlorite, or graphite. These are often interleaved with more granular minerals, such as feldspar or quartz. Schist typically forms during regional metamorphism accompanying the process of mountain building ( orogeny) and usually reflects a medium grade of metamorphism. Schist can form from many different kinds of rocks, including sedimentary rocks such as mudstones and igneous rocks such as tuffs. Schist metamorphosed from mudstone is particularly common and is often very rich in mica (a ''mica schist''). Where the type of the original rock (the protolith) is discernible, the schist is usually given a name reflecting its protolith, such as ''sch ...

Batholith
A batholith () is a large mass of intrusive igneous rock (also called plutonic rock), larger than in area, that forms from cooled magma deep in Earth's crust. Batholiths are almost always made mostly of felsic or intermediate rock types, such as granite, quartz monzonite, or diorite (see also ''granite dome''). Formation Although they may appear uniform, batholiths are in fact structures with complex histories and compositions. They are composed of multiple masses, or ''plutons'', bodies of igneous rock of irregular dimensions (typically at least several kilometers) that can be distinguished from adjacent igneous rock by some combination of criteria including age, composition, texture, or mappable structures. Individual plutons are solidified from magma that traveled toward the surface from a zone of partial melting near the base of the Earth's crust. Traditionally, these plutons have been considered to form by ascent of relatively buoyant magma in large masses call ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pluton
In geology, an igneous intrusion (or intrusive body or simply intrusion) is a body of intrusive igneous rock that forms by crystallization of magma slowly cooling below the surface of the Earth. Intrusions have a wide variety of forms and compositions, illustrated by examples like the Palisades Sill of New York and New Jersey; the Henry Mountains of Utah; the Bushveld Igneous Complex of South Africa; Shiprock in New Mexico; the Ardnamurchan intrusion in Scotland; and the Sierra Nevada Batholith of California. Because the solid country rock into which magma intrudes is an excellent insulator, cooling of the magma is extremely slow, and intrusive igneous rock is coarse-grained ( phaneritic). Intrusive igneous rocks are classified separately from extrusive igneous rocks, generally on the basis of their mineral content. The relative amounts of quartz, alkali feldspar, plagioclase, and feldspathoid is particularly important in classifying intrusive igneous rocks. Intrusi ...

Granite
Granite () is a coarse-grained ( phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or '' granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is near ...
