Devil's Gorge (Eifel)
The Devil's Gorge or Teufelsschlucht is located on the eastern edge of the Ferschweiler Plateau within the South Eifel Nature Park in the vicinity of Irrel. It was formed towards the end of the last ice age, about 10,000 years ago as the result of one or more rock collapses. The cause of this event was probably a combination of the geological and climatic circumstances. The heavily fissured, more or less porous, rock strata of the so-called Luxembourg Sandstone (geologically part of the Lower Jurassic or German Lias) are laid over keuper beds that tend towards being impervious. As weathering progresses, the structure becomes unstable as a result of the undercutting of the sandstone base. Towards the end of the last glaciation period this undercutting, in combination with extensive frost shattering 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferschweiler Plateau
The Ferschweiler Plateau, which is home to the villages of Ferschweiler and Ernzen among others, is an extensive highland area made from sandstone and is located in the collective municipality of Irrel in the county of Bitburg-Prüm in the German state of Rhineland-Palatinate. From a landscape perspective the Ferschweiler Plateau lies within the South Eifel, a region in the Eifel Mountains. The Ferschweiler Plateau is well known for its many Neolithic (New Stone Age) sites. Important sites include the Fraubillen cross which was originally from the megalithic culture and, according to the missionary, Willibrord, was re-fashioned by hand from a menhir over 4.50 metres high, but is now only 3.50 metres high. Also noteworthy are the Langstein ("Long Stone") and the ''Druidenstein'' ("Druid Rock"). At the back of the plateau is the Devil's Gorge as well as Neolithic and a Gallo-Roman grave field. The Ferschweiler Plateau is an escarpment (like the smaller neighbouring pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German-Luxembourg Nature Park
The German-Luxembourg Nature Park (german: Deutsch-Luxemburgische Naturpark) is a cross-border nature park, which was established on 17 April 1964 by state treaty between the German state of Rhineland-Palatinate and the Grand Duchy of Luxembourg. It thus became the first cross-border nature park in Western Europe.

Luxembourg Sandstone
The Luxembourg Sandstone (French: Grès de Luxembourg) is a geologic formation in Luxembourg. It exists along the eastern margin of the Paris Basin. Sandstone units continuous with the Luxembourg Sandstone also occur in France. It is Early Jurassic in age. It predominantly outcrops in a belt extending through south-central Luxembourg. It up to 100 metres thick and predominantly consists of carbonaceous poorly cemented sandstone and sandy limestone Fossil content Among others, the following fossils were reported from the formation:Luxembourg Sandstone at Fossilworks.org ;Reptiles * '' [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lower Jurassic
The Early Jurassic Epoch (in chronostratigraphy corresponding to the Lower Jurassic Series) is the earliest of three epochs of the Jurassic Period. The Early Jurassic starts immediately after the Triassic-Jurassic extinction event, 201.3 Ma (million years ago), and ends at the start of the Middle Jurassic 174.1 Ma. Certain rocks of marine origin of this age in Europe are called "Lias" and that name was used for the period, as well, in 19th-century geology. In southern Germany rocks of this age are called Black Jurassic. Origin of the name Lias There are two possible origins for the name Lias: the first reason is it was taken by a geologist from an English quarryman's dialect pronunciation of the word "layers"; secondly, sloops from north Cornish ports such as Bude would sail across the Bristol Channel to the Vale of Glamorgan to load up with rock from coastal limestone quarries (lias limestone from South Wales was used throughout North Devon/North Cornwall as it con ...

Keuper
The Keuper is a lithostratigraphic unit (a sequence of rock strata) in the subsurface of large parts of west and central Europe. The Keuper consists of dolomite, shales or claystones and evaporites that were deposited during the Middle and Late Triassic epochs (about ). The Keuper lies on top of the Muschelkalk and under the predominantly Lower Jurassic Lias or other Early Jurassic strata. The Keuper together with the Muschelkalk and the Buntsandstein form the Germanic Trias Group, a characteristic sequence of rock strata that gave the Triassic its name. "Muschelkalk (geology)", Britannica Online Encyclopedia, October 2010, webpage: EB-39 Exposure The Upper Triassic is well exposed in Swabia, Franconia, Alsace and Lorraine and Luxembourg; it extends from Basel on the east side of the Rhine into Hanover, and through England into Scotland and north-east Ireland; it appears flanking the central plateau of France and in the Pyrenees and Sardinia. The Keuper sequence is li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frost Shattering
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 ...

Eifel
The Eifel (; lb, Äifel, ) is a low mountain range in western Germany and eastern Belgium. It occupies parts of southwestern North Rhine-Westphalia, northwestern Rhineland-Palatinate and the southern area of the German-speaking Community of Belgium. The Eifel is part of the Rhenish Massif; within its northern portions lies the Eifel National Park. Geography Location The Eifel lies between the cities of Aachen to the north, Trier to the south and Koblenz to the east. It descends in the northeast along a line from Aachen via Düren to Bonn into the Lower Rhine Bay. In the east and south it is bounded by the valleys of the Rhine and the Moselle. To the west it transitions in Belgium and Luxembourg into the geologically related Ardennes and the Luxembourg Ösling. In the north it is limited by the Jülich-Zülpicher Börde. Within Germany it lies within the states of Rhineland-Palatinate and North Rhine-Westphalia; in the Benelux the area of Eupen, St. Vith and Luxemb ...

Valleys Of Rhineland-Palatinate
A valley is an elongated low area often running between Hill, hills or Mountain, mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacier, glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glaciation, glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In karst, areas of limestone bedrock, dry valleys may also result from drainage now taking place cave, underground rather than at the surface. Rift valleys arise principally from tectonics, earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms th ...

Canyons And Gorges Of Germany
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examples of mountain-type c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
