Hans Reusch
Hans Henrik Reusch (5 September 1852 – 27 October 1922) was a Norwegian geologist, geomorphologist and educator. He served as director of the Geological Survey of Norway. Biography Born in Bergen, he was educated at the University of Leipzig and Heidelberg University. He graduated Ph.D. at the University of Christiania (now University of Oslo) in 1883. He was married to the painter Helga Marie Ring Reusch He joined the Geological Survey of Norway in 1875, and was its Director from 1888 to 1921. He was a Sturgis Hooper Professor of Geology at Harvard University (1897–98). He is distinguished for his research on the crystalline schists and the Palaeozoic rocks of Norway. He discovered Silurian fossils in the highly altered rocks of the Bergen region; and in 1891 he called attention to the so-called "Reusch's Moraine" a Precambrian conglomerate of glacial origin in the Varanger Fjord, a view confirmed by A. Strahan in 1896, who found glacial striations on the rocks b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...

Crystal
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. The word ''crystal'' derives from the Ancient Greek word (), meaning both "ice" and "rock crystal", from (), "icy cold, frost". Examples of large crystals include snowflakes, diamonds, and table salt. Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. Polycrystals include most metals, rocks, ceramics, and ice. A third category of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hvalstad Station
Hvalstad Station ( no, Hvalstad stasjon) is a railway station of the Drammen Line located at Hvalstad in Asker, Norway. Situated from Oslo Central Station, it consists of an island platform and serves the L1 line of the Oslo Commuter Rail operated by Vy. The station served 233,000 passengers in 2012. The line opened at the same time as the Drammen Line on 7 October 1872. The first station building was a wooden structure designed by Georg Andreas Bull. The station was moved in 1915 to its current location. This resulted in another wooden station building, designed by Jens Flor. The third station building, designed by Julie Kristiansen, was completed in 1957. This resulted in the station being raised to an elevated structure. Bull's building has been demolished, while Flor's and Kristiansen's have been listed as heritage sites. History Hvalstad was along with Asker Station the only stations to be opened along with the Drammen Line on 8 October 1872.Bjerke & Holom: 189 The first ...

Oxford University
Oxford () is a city in England. It is the county town and only city of Oxfordshire. In 2020, its population was estimated at 151,584. It is north-west of London, south-east of Birmingham and north-east of Bristol. The city is home to the University of Oxford, the oldest university in the English-speaking world; it has buildings in every style of English architecture since late Anglo-Saxon. Oxford's industries include motor manufacturing, education, publishing, information technology and science. History The history of Oxford in England dates back to its original settlement in the Saxon period. Originally of strategic significance due to its controlling location on the upper reaches of the River Thames at its junction with the River Cherwell, the town grew in national importance during the early Norman period, and in the late 12th century became home to the fledgling University of Oxford. The city was besieged during The Anarchy in 1142. The university rose to domina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norwegian Geographical Society
The Norwegian Geographical Society (in Norwegian: Det norske geografiske Selskab) is a Norwegian learned society founded in 1889. Among the initiators was geologist Hans Henrik Reusch, who chaired the society from 1898 to 1903, and again from 1907 to 1909, and was also an honorary member. In a speech at the society in January 1890 polar researcher Fridtjof Nansen proposed the Fram expedition, an attempt to reach the North Pole, and the building of the polar ship Fram. The society has published the ''Norwegian Journal of Geography __NOTOC__ ''Norwegian Journal of Geography'' ( no, Norsk Geografisk Tidsskrift) is a peer-reviewed scientific journal published by Routledge on behalf of the Norwegian Geographical Society.

Naturen
''Naturen'' ( en, Nature) is a Norwegian popular science magazine, which has been published since 1877 in Bergen, Norway. It is the earliest still running popular science magazine of the country. History and profile ''Naturen'' was started by the geologist Hans Reusch in Bergen in 1877. It was subtitled ''Et illustreret Maanedsskrift for popular Naturvidenskab'' (An Illustrated Monthly for Popular Natural Sciences). It is connected to the University of Bergen. It has a popular science approach to the natural sciences, including medicine. ''Naturen'' was edited by its founder, Hans Reusch, for the first four years. Among its former editors are Jens Holmboe (1906–1925), Torbjørn Gaarder (1925–1946) and Knut Fægri (1947–1977), and Per Magnus Jørgensen Per Magnus Jørgensen (born 1944) is a Norwegian botanist and lichenologist, and Professor Emeritus of systematic botany at the University of Bergen.

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Varanger Fjord
The Varangerfjord ( en, Varanger Fjord; russian: Варангер-фьорд, Варяжский залив; fi, Varanginvuono; sme, Várjavuonna) is the easternmost fjord in Norway, north of Finland. The fjord is located in Troms og Finnmark county between the Varanger Peninsula and the mainland of Norway. The fjord flows through the municipalities of Vardø, Vadsø, Nesseby, and Sør-Varanger. The fjord is approximately long, emptying into the Barents Sea. In a strict sense, it is a false fjord, since it does not have the hallmarks of a fjord carved by glaciers. Its mouth is about wide, located between the town of Vardø in the northwest and the village of Grense Jakobselv in the southeast. The fjord stretches westwards inland past the town of Vadsø to the village of Varangerbotn in Nesseby Municipality. History The ''Kven'' residents of ''Varangerfjord'' are largely descendants of Finnish immigrants who arrived to the area during the 19th century from Finland and northe ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Conglomerate (geology)
Conglomerate () is a clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel-size clasts. A conglomerate typically contains a matrix of finer-grained sediments, such as sand, silt, or clay, which fills the interstices between the clasts. The clasts and matrix are typically cemented by calcium carbonate, iron oxide, silica, or hardened clay. Conglomerates form by the consolidation and lithification of gravel. 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. In terms of origin and depositional mechanisms, they are closely related to sandstones and exhibit many of the same types of sedimentary structures, e.g., tabular and trough cross-bedding and graded bedding.Boggs, S.

Precambrian
The Precambrian (or Pre-Cambrian, sometimes abbreviated pꞒ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian is an informal unit of geologic time, subdivided into three eons ( Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago ( Ga) to the beginning of the Cambrian Period, about million years ago ( Ma), when hard-shelled creatures first appeared in abundance. Overview Relatively little is known about the Precambrian, despite it making up roughly seven-eighths of the Earth's history, and what is known has largely been discovered from the 1960s onwards.
