Swabian Alb
The Swabian Jura ( , more rarely ), sometimes also named Swabian Alps in English, is a mountain range in Baden-Württemberg, Germany, extending from southwest to northeast and in width. It is named after the region of Swabia. It is part of the Table Jura (). The Swabian Jura occupies the region bounded by the Danube in the southeast and the upper Neckar in the northwest. In the southwest it rises to the higher mountains of the Black Forest. The highest mountain in the region is the Lemberg (). The area's profile resembles a high plateau, which slowly falls away to the southeast. The northwestern edge is a steep escarpment (called the Albtrauf or Albanstieg, rising up , covered with forests), while the top is flat or gently rolling. In economic and cultural terms, the Swabian Jura includes regions just around the mountain range. It is a popular recreation area. The whole ''Schwäbische Alb'' area is a UNESCO global geopark covering 6,688 km2 (2582 sq mi.); it was designated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Jurassic
The White Jurassic or White 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 unit of the Brow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhine
The Rhine ( ) is one of the List of rivers of Europe, major rivers in Europe. The river begins in the Swiss canton of Graubünden in the southeastern Swiss Alps. It forms part of the Swiss-Liechtenstein border, then part of the Austria–Switzerland border, Swiss-Austrian border. From Lake Constance downstream, it forms part of the Germany-Switzerland border, Swiss-German border. After that the Rhine defines much of the Franco-German border. It then flows in a mostly northerly direction through the German Rhineland. Finally, the Rhine turns to flow predominantly west to enter the Netherlands, eventually emptying into the North Sea. It drains an area of 185,000 km2. Its name derives from the Gaulish language, Gaulish ''Rēnos''. There are two States of Germany, German states named after the river, North Rhine-Westphalia and Rhineland-Palatinate, in addition to several districts of Germany, districts (e.g. Rhein-Sieg-Kreis, Rhein-Sieg). The departments of France, department ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aachtopf
The Aachtopf () is Germany's biggest karst spring, south of the western end of the Swabian Jura near the town of Aach, Baden-Württemberg, Aach. It produces an average of 8,500 litres per second. Most of the water stems from the River Danube where it disappears underground at the Danube Sinkhole, north near Immendingen and about north near Fridingen. The cave system has been explored since the 1960s, but as of 2020 only a small part has been discovered due to a large blockage after a few hundred metres. Etymology The name Aachtopf is compounded from ''Aach'' (meaning "water" in Old High German); ''Topf'' can be translated as "bowl" and is commonly used for round, bowl-shaped springs. Geography The Aachtopf is a karst spring, south of the western end of the Swabian Jura near the town of Aach, Baden-Württemberg, Aach. The spring is the source of the river Radolfzeller Aach, which flows southward into Lake Constance, and empties into the Rhine. Origin The spring marks the sou ...

Immendingen
Immendingen is a municipality in the district of Tuttlingen (district), Tuttlingen in Baden-Württemberg in Germany located on the Upper Danube Nature Park, Upper Danube. It is famous for the Danube Sinkhole. Geography Immendingen is located on the Upper Danube Nature Park, Upper Danube. On the municipal area are parts of the Danube Sinkhole. With the mountain Höwenegg in Immendingen begins the extinct volcanic landscape of Hegau. Archaeological excavations at the Höwenegg recover saber-toothed tigers, antelopes and one of the few well preserved ancestral horses. The municipality borders Talheim to the north, Tuttlingen to the east, Emmingen-Liptingen to the southeast, Engen to the south, and Geisingen and Bad Durrheim to the west. The whole municipality with the previously independent municipalities Hattingen, Hintschingen, Ippingen, Mauenheim and Zimmern include 22 villages, hamlets, farms and houses.

Blautopf
The Blautopf (German for ''Blue pot'') is a Spring (hydrosphere), spring that is considered the source of the river Blau (Danube), Blau in the karst landscape on the Swabian Jura's southern edge. It is located in Blaubeuren, Alb-Donau-Kreis, Baden-Württemberg, Germany (approximately west of Ulm). Description It forms the drain for the Blau cave system; the river Blau after flows into the river Danube in the city of Ulm. Because of its high water pressure, the spring has developed a funnel-like shape with a depth of 21 metres (69 ft). The water's peculiarly blue color, varying in intensity depending on weather and flow, is the result of physical properties of the nanoscale limestone particles densely distributed in the water. They cause Rayleigh scattering of light, preferentially scattering the blue color of the visible light. A similar effect is observed at the Blue Lagoon (geothermal spa), Blue Lagoon near Reykjavík, where the color originates from nanoscale Silicon di ...

Speleothem
A speleothem (; ) is a geological formation made by mineral deposits that accumulate over time in natural caves. Speleothems most commonly form in calcareous caves due to carbonate dissolution reactions. They can take a variety of forms, depending on their depositional history and environment. Their chemical composition, gradual growth, and preservation in caves make them useful paleoclimatic proxies. Chemical and physical characteristics More than 300 variations of cave mineral deposits have been identified. The vast majority of speleothems are calcareous, composed of calcium carbonate (CaCO3) minerals (calcite or aragonite). Less commonly, speleothems are made of calcium sulfate ( gypsum or mirabilite) or opal. Speleothems of pure calcium carbonate or calcium sulfate are translucent and colorless. The presence of iron oxide or copper provides a reddish brown color. The presence of manganese oxide can create darker colors such as black or dark brown. Speleothems can also b ...

Inliers And Outliers (geology)
An inlier is an area of older rocks surrounded by younger rocks. Inliers are typically formed by the erosion of overlying younger rocks to reveal a limited exposure of the older underlying rocks. Faulting or folding may also contribute to the observed outcrop pattern. A classic example from Great Britain is that of the inlier of folded Ordovician and Silurian rocks at Horton in Ribblesdale in North Yorkshire which are surrounded by the younger flat-lying Carboniferous Limestone. The location has long been visited by geology students and experts. Another example from South Wales is the Usk Inlier in Monmouthshire where Silurian age rocks are upfolded amidst Old Red Sandstone rocks of Devonian age. A similar outcrop pattern which results from movement on a thrust fault followed by erosion may be termed a window. Conversely an outlier is an area of younger rock surrounded by older rocks. An outlier is typically formed when sufficient erosion of surrounding rocks has taken plac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Turritellenplatte
The Turritellenplatte of Ermingen ("Erminger Turritellenplatte" near Ulm, Germany) is a type of very rich, fossil-bearing rock which is of particular interest to geologists and paleontologists. It occurs in a very restricted outcrop and is protected in its entirety as a natural monument. This outcrop of these marine sedimentary rocks is situated in the northern part of the North Alpine Foreland Basin (NAFB) and it is famous for a superabundance of shells of the sea snail '' Turritella turris'', a marine gastropod mollusk in the family Turritellidae. The fauna of this gastropod-rich sandstone reflects mainly near-coastal and shallow marine conditions. Petrographical and palaeontological data allow a correlation of the ''Turritellenplatte'' of Ermingen with Burdigalian (Lower Miocene). The Sr-isotope composition of shark Sharks are a group of elasmobranch cartilaginous fish characterized by a ribless endoskeleton, dermal denticles, five to seven gill slits on each side, an ...

Nördlinger Ries
The Nördlinger Ries is an impact crater and large circular depression in western Bavaria and eastern Baden-Württemberg. It is located north of the Danube in the district of Donau-Ries. The city of Nördlingen is located within the depression, about south-west of its centre. Etymology "Ries" is derived from Raetia, since the tribe of Raetians lived in the area in pre- Roman times. Description The depression is a meteorite impact crater formed 14.808 ± 0.038 million years ago in the Miocene. The crater is most commonly referred to simply as the ''Ries crater'' or ''the Ries''. The original crater rim had an estimated diameter of . The present floor of the depression is about below the eroded remains of the rim. It was originally assumed that the Ries was of volcanic, glacial or tectonic origin. Oliver Sachs introduced, in this context, the term "pioneer era" (up to 1870) and marked the beginning of early modern research on the Ries (from 1870), meaning the perio ...

Maar
A maar is a broad, low-relief volcanic crater caused by a phreatomagmatic eruption (an explosion which occurs when groundwater comes into contact with hot lava or magma). A maar characteristically fills with water to form a relatively shallow crater lake, which may also be called a maar.David S.G. Thomas and Andrew Goudie (eds.), ''The Dictionary of Physical Geography'' (Oxford: Blackwell, 2000), 301. . Maars range in size from across and from deep. Most maars fill with water to form natural lakes. Most maars have low rims composed of a mixture of loose fragments of volcanic rocks and rocks torn from the walls of the diatreme. Etymology The name ''maar'' comes from a Moselle Franconian dialect word used for the circular lakes of the Daun area of Germany. The word evolved from its first use in German in the modern geological sense in 1819 and is now used in English and in the geological sciences as the term for the explosion crater, even if water from rainfall might alway ...
