Scharfenstein (Hesse)
Scharfenstein is a hill composed of basalt in the Schwalm-Eder-Kreis district of North Hesse, Germany. It is the remains of one of a number of extinct volcanoes in the West Hesse Depression. Geographical Location Scharfenstein lies ca. north-east of the town centre of Gudensberg, and ca. west-south-west of the village of Dissen. Directly next to it runs the Bundesautobahn 49, and the hill can be reached from a car park off the autobahn. Alternatively the outcrop can be reached on foot from Dissen by crossing a bridge over the autobahn. Geology The hill is the remains of an extinct volcano that belongs to the West Hesse Depression. The volcano was active in the Miocene, i.e. it began 20 million years ago and ended 7 million years ago. The only part of the volcano that is left is the neck or volcanic plug; the rest has been eroded. The alkali basalt has a silica (SiO2) volume percentage of 45-55%. The main minerals in the rock are plagioclase, augite and olivine. Peculi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Normalhöhennull
' ("standard elevation zero") or NHN is a vertical datum used in Germany. In geographical terms, NHN is the reference plane for the normal height of a topographical eminence height above mean sea level used in the 1932 German Mean Height Reference System ('). The plane is in the shape of a quasi-geoid. The reference height is a geodetic, fixed point on the New Church of St. Alexander at Wallenhorst in the German state of Lower Saxony. The geopotential height of this point was calculated in 1986 as part of the United European Levelling Network (UELN), based on the Amsterdam Ordnance Datum. Definition The NHN plane is a theoretical reference plane. It is derived by deducting normal heights from the normal plumb line. The difference between the resulting quasi-geoid and the reference ellipsoid is called the height anomaly or quasi-geoid height. Change-over from NN to NHN Since 1 January 2000 the whole of Germany has changed its height system over to normal heights based on ...

Augite
Augite is a common rock-forming pyroxene mineral with formula . The crystals are monoclinic and prismatic. Augite has two prominent cleavages, meeting at angles near 90 degrees. Characteristics Augite is a solid solution in the pyroxene group. Diopside and hedenbergite are important endmembers in augite, but augite can also contain significant aluminium, titanium, and sodium and other elements. The calcium content of augite is limited by a miscibility gap between it and pigeonite and orthopyroxene: when occurring with either of these other pyroxenes, the calcium content of augite is a function of temperature and pressure, but mostly of temperature, and so can be useful in reconstructing temperature histories of rocks. With declining temperature, augite may exsolve lamellae of pigeonite and/or orthopyroxene. There is also a miscibility gap between augite and omphacite, but this gap occurs at higher temperatures. There are no industrial or economic uses for this mineral. Locatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brothers Grimm
The Brothers Grimm ( or ), Jacob (1785–1863) and Wilhelm (1786–1859), were a brother duo of German academics, philologists, cultural researchers, lexicographers, and authors who together collected and published folklore. They are among the best-known storytellers of folk tales, popularizing stories such as "Cinderella" ("), "The Frog Prince" (""), "Hansel and Gretel" ("), "Little Red Riding Hood" (""), "Rapunzel", "Rumpelstiltskin" (""), "Sleeping Beauty" (""), and "Snow White" (""). Their first collection of folk tales, ''Children's and Household Tales'' (), began publication in 1812. The Brothers Grimm spent their formative years in the town of Hanau in the Landgraviate of Hesse-Kassel. Their father's death in 1796 (when Jacob was eleven and Wilhelm was ten) caused great poverty for the family and affected the brothers many years after. Both brothers attended the University of Marburg, where they developed a curiosity about German folklore, which grew into a lifelong de ...

Ludwig Emil Grimm
Ludwig Emil Grimm (14 March 1790 – 4 April 1863) was a German painter, art professor, etcher and copper engraver. Early life Grimm was born in Hanau, Germany, in 1790. His brothers Jacob and Wilhelm Grimm were folklorists. Education Grimm studies began at the Kunsthochschule Kassel and Philip Otto Runge, then from 1809 to 1817, he studied at Academy of Fine Arts Munich. In the 1814, he worked as an officer in the campaign against Napoleon. In 1816, he travelled to Italy where he learned engraving from Carl Ernst Christoph Hess and published his first work; a sketchbook of engravings based on his Italian journey. Career In 1819, Grimm contributed the frontispiece for the second edition of ''Kinder- und Hausmärchen'' (Grimm's Fairy Tales). In 1823 and 1826 he was able to secure commissions for two series of portraits of scholars, professors and doctors, thanks to his brothers' connections to the academic community in Göttingen. In 1832, he helped Gerhardt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanctuary
A sanctuary, in its original meaning, is a sacred place, such as a shrine. By the use of such places as a haven, by extension the term has come to be used for any place of safety. This secondary use can be categorized into human sanctuary, a safe place for people, such as a political sanctuary; and non-human sanctuary, such as an animal or plant sanctuary. Religious sanctuary ''Sanctuary'' is a word derived from the Latin , which is, like most words ending in , a container for keeping something in—in this case holy things or perhaps cherished people (/). The meaning was extended to places of holiness or safety, in particular the whole demarcated area, often many acres, surrounding a Greek or Roman temple; the original terms for these are ''temenos'' in Greek and ''fanum'' in Latin, but both may be translated as "sanctuary". Similar usage may be sometimes found describing sacred areas in other religions. In Christian churches ''sanctuary'' has a specific meaning, covering p ...

Warrior
A warrior is a person specializing in combat or warfare, especially within the context of a tribal or clan-based warrior culture society that recognizes a separate warrior aristocracies, class, or caste. History Warriors seem to have been present in the earliest pre-state societies. Scholars have argued that horse-riding Yamnaya warriors from the Pontic–Caspian steppe played a key role during the Indo-European migrations and the diffusion of Indo-European languages across Eurasia. Most of the basic weapons used by warriors appeared before the rise of most hierarchical systems. Bows and arrows, clubs, spears, swords, and other edged weapons were in widespread use. However, with the new findings of metallurgy, the aforementioned weapons had grown in effectiveness. When the first hierarchical systems evolved 5000 years ago, the gap between the rulers and the ruled had increased. Making war to extend the outreach of their territories, rulers often forced men from lower orders ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Rome
In modern historiography, ancient Rome refers to Roman civilisation from the founding of the city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), Roman Republic (509–27 BC) and Roman Empire (27 BC–476 AD) until the fall of the western empire. Ancient Rome began as an Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian Peninsula. The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually dominated the Italian Peninsula, assimilated the Greek culture of southern Italy ( Magna Grecia) and the Etruscan culture and acquired an Empire that took in much of Europe and the lands and peoples surrounding the Mediterranean Sea. It was among the largest empires in the ancient world, with an estimated 50 to 90 million inhabitants, roughly 20% of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franz Von Dingelstedt
Franz von Dingelstedt (30 June 1814 – 15 May 1881) was a German poet, dramatist and theatre administrator. Life and career Dingestedt was born at Halsdorf, Hesse-Kassel (or Hesse-Cassel), Germany, and later studied at the University of Marburg nearby. In 1836 he became a master at the Lyceum in Kassel, from where he was transferred to Fulda in 1838. In 1839 he wrote ''Unter der Erde'' ("Beneath the Earth"), a novel which obtained considerable success. In 1841, ''Lieder eines kosmopolitischen Nachtwächters'', the book by which he is best remembered, was published. These poems, animated as they are by a spirit of bitter opposition to everything that savours of despotism, were an effective contribution to the political poetry of the day. The popularity of this book determined Dingelstedt to take up a literary career, and in 1841 he obtained an appointment on the staff of the ''Augsburger Allgemeine Zeitung''. In 1843, however, the satirist of German princes accepted, to general s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frost Weathering
Frost weathering is a collective term for several mechanical weathering processes induced by stresses created by the freezing of water into ice. The term serves as an umbrella term for a variety of processes such as frost shattering, frost wedging and cryofracturing. The process may act on a wide range of spatial and temporal scales, from minutes to years and from dislodging mineral grains to fracturing boulders. It is most pronounced in high-altitude and high-latitude areas and is especially associated with alpine, periglacial, subpolar maritime and polar climates, but may occur anywhere at sub-freezing temperatures (between -3 and -8 °C) if water is present. Ice segregation Certain frost-susceptible soils expand or heave upon freezing as a result of water migrating via capillary action to grow ice lenses near the freezing front. This same phenomenon occurs within pore spaces of rocks. The ice accumulations grow larger as they attract liquid water from the surrounding ...

Basalt Fan Structure
A basalt fan structure is a basalt formation composed of columnar jointed basalt columns that have slumped into a fan shape. They are most likely created when basalt lava is intruded into a soft material, such as loose volcanic A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

Intrusion
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. Intrusions ...

Volcanic Eruption (manga)
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic ...
