Bunter (geology)
Bunter Pebble Beds is the name formerly given to a set of sandstone deposits within the New Red Sandstone containing rounded pebbles. They are thought to be alluvial deposits and, judging from the rounding of the mainly quartzite pebbles, to have resulted from prolonged transportation in a large and turbulent river, resulting in powerful abrasion. Etymology The name "Bunter" derives from the German term "Buntsandstein", "bunt" meaning "variegated" or "colourful", referring to the colour of the sandstone deposit, which varies from reddish to greenish. Utility The pebbles, also called cobbles, which can be used as gravel, as ballast or as cobblestones, are mainly milky-white quartzite but can vary in colour and composition, including some that are hard, reddish-coloured sandstone. The sandstone in which these pebbles are deposited can be used for building or as an aggregate for cement or concrete. The sandstone can be hard enough for building, yet easy enough to "work", result ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually relate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Strasbourg Cathedral
Strasbourg Cathedral or the Cathedral of Our Lady of Strasbourg (french: Cathédrale Notre-Dame de Strasbourg, or ''Cathédrale de Strasbourg'', german: Liebfrauenmünster zu Straßburg or ''Straßburger Münster''), also known as Strasbourg Minster, is a Catholic cathedral in Strasbourg, Alsace, France. Although considerable parts of it are still in Romanesque architecture, it is widely consideredSusan Bernstein''Goethe's Architectonic Bildung and Buildings in Classical Weimar'' The Johns Hopkins University Press to be among the finest examples of Rayonnant Gothic architecture. Architect Erwin von Steinbach is credited for major contributions from 1277 to his death in 1318, and beyond through his son Johannes von Steinbach, and his grandson Gerlach von Steinbach, who succeeded him as chief architects. The Steinbachs's plans for the completion of the cathedral were not followed through by the chief architects who took over after them, and instead of the originally envisioned ...

Odenwald
The Odenwald () is a low mountain range in the German states of Hesse, Bavaria and Baden-Württemberg. Location The Odenwald is located between the Upper Rhine Plain with the Bergstraße and the ''Hessisches Ried'' (the northeastern section of the Rhine rift) to the west, the Main and the Bauland (a mostly unwooded area with good soils) to the east, the Hanau-Seligenstadt Basin – a subbasin of the Upper Rhine Rift Valley in the Rhine-Main Lowlands – to the north and the Kraichgau to the south. The part south of the Neckar valley is sometimes called the ''Kleiner Odenwald'' ("Little Odenwald"). The northern and western Odenwald belong to southern Hesse, with the south stretching into Baden. In the northeast, a small part lies in Lower Franconia in Bavaria. Geology The Odenwald, along with other parts of the Central German Uplands, belongs to the Variscan, which more than 300 million years ago in the Carboniferous period ran through great parts of Europe.

Palatinate (region)
The Palatinate (german: Pfalz; Palatine German: ''Palz'') is a region of Germany. In the Middle Ages it was known as the Rhenish Palatinate (''Rheinpfalz'') and Lower Palatinate (''Unterpfalz''), which strictly speaking designated only the western part of the Electorate of the Palatinate (''Kurfürstentum Pfalz''), as opposed to the Upper Palatinate (''Oberpfalz''). It occupies roughly the southernmost quarter of the German federal state of Rhineland-Palatinate (''Rheinland-Pfalz''), covering an area of with about 1.4 million inhabitants. Its residents are known as Palatines (''Pfälzer''). Geography The Palatinate borders Saarland in the west, historically also comprising the state's Saarpfalz District. In the northwest, the Hunsrück mountain range forms the border with the Rhineland region. The eastern border with Hesse and the Baden region runs along the Upper Rhine river, while the left bank, with Mainz and Worms as well as the Selz basin around Alzey, belong to ...

Electoral Palatine
The Electoral Palatinate (german: Kurpfalz) or the Palatinate (), officially the Electorate of the Palatinate (), was a state that was part of the Holy Roman Empire. The electorate had its origins under the rulership of the Counts Palatine of Lotharingia from 915, it was then restructured under the Counts Palatine of the Rhine in 1085. These counts palatine of the Rhine would serve as prince-electors () from "time immemorial", and were noted as such in a papal letter of 1261, they were confirmed as electors by the Golden Bull of 1356. The territory stretched from the left bank of the Upper Rhine, from the Hunsrück mountain range in what is today the Palatinate region in the German federal state of Rhineland-Palatinate and the adjacent parts of the French regions of Alsace and Lorraine (bailiwick of Seltz from 1418 to 1766) to the opposite territory on the east bank of the Rhine in present-day Hesse and Baden-Württemberg up to the Odenwald range and the southern Kraichgau re ...

Granite
Granite () is a coarse-grained ( phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or '' granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is near ...

Outcrop
An outcrop or rocky outcrop is a visible exposure of bedrock or ancient superficial deposits on the surface of the Earth. Features Outcrops do not cover the majority of the Earth's land surface because in most places the bedrock or superficial deposits are covered by soil and vegetation and cannot be seen or examined closely. However, in places where the overlying cover is removed through erosion or tectonic uplift, the rock may be exposed, or ''crop out''. Such exposure will happen most frequently in areas where erosion is rapid and exceeds the weathering rate such as on steep hillsides, mountain ridges and tops, river banks, and tectonically active areas. In Finland, glacial erosion during the last glacial maximum (ca. 11000 BC), followed by scouring by sea waves, followed by isostatic uplift has produced many smooth coastal and littoral outcrops. Bedrock and superficial deposits may also be exposed at the Earth's surface due to human excavations such as quarrying and build ...

Heidelberg Castle
Heidelberg Castle (german: Heidelberger Schloss) is a ruin in Germany and landmark of Heidelberg. The castle ruins are among the most important Renaissance structures north of the Alps. The castle has only been partially rebuilt since its demolition in the 17th and 18th centuries. It is located up the northern part of the Königstuhl hillside, and thereby dominates the view of the old downtown. It is served by an intermediate station on the Heidelberger Bergbahn funicular railway that runs from Heidelberg's Kornmarkt to the summit of the Königstuhl. The earliest castle structure was built before 1214 and later expanded into two castles circa 1294; however, in 1537, a lightning bolt destroyed the upper castle. The present structures had been expanded by 1650, before damage by later wars and fires. In 1764, another lightning bolt caused a fire which destroyed some rebuilt sections.
