Hersbrucker Alb
The Hersbrucker Alb ("Hersbruck Jura") – also called ''Hersbrucker Schweiz'' ("Hersbruck Switzerland") or ''Pegnitz-Alb'' ("Pegnitz Jura") – is the northeastern part of the Franconian Jura near the town of Hersbruck. The River Pegnitz and its tributaries flow through the region. Location In the west the Hersbrucker Alb reaches the valley of the Schnaittach. It is bounded by the course of the Pegnitz and Hiltpoltstein to the west, Betzenstein to the north, Auerbach in der Oberpfalz and Sulzbach-Rosenberg to the east and Alfeld (Mittelfranken) to the south. Much of it lies within the Bavarian provinces of Middle Franconia and the Upper Palatinate; a small part is in Upper Franconia. The Hersbrucker Alb is formed from the White Jura platform of hard, brittle and karstified massive and Corallian Limestones and the Franconian dolomite together with their more recent depositions. Numerous caves and a striking rock landscape have resulted in the area being referred to as "Hersb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Upper Franconia
Upper Franconia (german: Oberfranken) is a ''Regierungsbezirk'' (administrative 'Regierungs''region 'bezirk'' of the state of Bavaria, southern Germany. It forms part of the historically significant region of Franconia, the others being Middle Franconia and Lower Franconia, which are all now part of the German Federal State of Bayern (''Bavaria''). With more than 200 independent breweries which brew approximately 1000 different types of beer, Upper Franconia has the world's highest brewery-density per capita. A special Franconian beer route (''Fränkische Brauereistraße'') runs through many popular breweries. Geography The administrative region borders on Thuringia (''Thüringen'') to the north, Lower Franconia (''Unterfranken'') to the west, Middle Franconia (''Mittelfranken'') to the south-west, and Upper Palatinate (''Oberpfalz'') to the south-east, Saxony (''Sachsen'') to the north-east and the Czech Republic to the east.

Central Uplands
The Central UplandsDickinson (1964), p.18 ff. (german: die MittelgebirgeN.B. In German die ''Mittelgebirge'' (plural) refers to the Central Uplands; das ''Mittelgebirge'' refers to a low mountain range or upland region (''Mittel'' = "medium" and ''-gebirge'' = "range").) is one of the three major natural regions of Germany. It stretches east to west across the country. To the north lies the North German Plain or Northern Lowland; to the south, the Alps and the Alpine Foreland. Formation The German Central Uplands, like the Scandinavian and British mountain ranges and the Urals, belong to the oldest mountains of Europe, even if their present-day appearance has only developed relatively recently. In the Carboniferous, i.e. about 350 million years ago, Variscan mountain ranges were formed in central Europe by the uplifting caused by tectonic plate collision. Immediately after their formation the erosion of the mountains began under the influence of exogenous processes during the ...

Cave
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgani ...

Dolomite (rock)
Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO3)2. It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 66 million years in age). The first geologist to distinguish dolomite rock from limestone was Belsazar Hacquet in 1778. Most dolomite was formed as a magnesium replacement of limestone or of lime mud before lithification. The geological process of conversion of calcite to dolomite is known as dolomitization and any intermediate product is known as dolomitic limestone. The "dolomite problem" refers to the vast worldwide depositions of dolomite in the past geologic record in contrast to the limited amounts of dolomite formed in modern times. Recent research has revealed sulfate-reducing bacteria living in anoxic conditions precipitate dolomite which ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corallian Limestone
The Corallian Group or Corallian Limestone is a geologic group in England. It is predominantly a coralliferous sedimentary rock, laid down in the Oxfordian stage of the Jurassic. It is a hard variety of "coral rag". Building stones from this geological structure tend to be irregular in shape. It is often found close to seams of Portland Limestone (e.g. Abbotsbury in Dorset, England). It is a younger limestone than its near-neighbour, the Oolitic, as found in the Cotswolds, in Gloucestershire. It is laterally equivalent to and interfingers with units of the Ancholme Group. A ridge of Corallian Limestone rises above the Vale of Avon and the Thames Valley in its Oxfordshire stretch. The Oxfordshire Corallian ridge is an escarpment holding back the hanging valley that is the Vale of White Horse and its hardness forced the River Thames to take a wide northern detour, to cut through the low ridge at Oxford. High points along the ridge are Cumnor Hurst and Wytham Hill. The outcrop kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karstified
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier. ...

White Jura
The White Jurassic or White Jura (german: Weißer Jura or ''Weißjura'') in earth history refers to the upper of the three lithostratigraphic units of the South German Jurassic, the latter being understood not as a geographical, but a geological term in the sense of a lithostratigraphic super group. Formerly and even occasionally today in the popular scientific literature, this term is equated to the chronostratigraphic series of the Upper Jurassic. This is however not quite correct, because the White Jura does not exactly coincide with the chronostratigraphic boundaries of the Upper Jurassic. In addition, the term ''Malm'', which was formerly frequently used as a synonym should no longer be used in connexion with the South German Jurassic. Instead the term "Malm" should be reserved for the roughly equivalent lithostratigraphic unit in the North German Jurassic. The White Jurassic was deposited about 161-150 million years ago. The White Jurassic follows the lithostratigraphic un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Palatinate
The Upper Palatinate (german: Oberpfalz, , ) is one of the seven administrative districts of Bavaria, Germany, and is located in the east of Bavaria. Geography The Upper Palatinate is a landscape with low mountains and numerous ponds and lakes in its lowland regions. By contrast with other regions of Germany it is more rural in character and more sparsely settled. It borders (clockwise from the north) on Upper Franconia, the Czech Republic, Lower Bavaria, Upper Bavaria and Middle Franconia. Notable regions are: * Stiftland, former estate and territorial lordship of Waldsassen Abbey with the market town of Konnersreuth, Fockenfeld Abbey, the town of Waldsassen and about 150 other villages. * Upper Palatine Forest with deep valleys and many castles * Upper Palatine Lake District with the Steinberger See * Upper Palatine Jura, part of the Franconian Jura * Steinwald including the Teichelberg and Pechbrunn * Waldnaab/ Wondreb Depression * Bavarian Forest, together with ...
