40-530: The Kleiner Feldberg is the second-highest mountain in the Taunus mountain range, located in Hesse , Germany . It has an elevation of 826 metres (2,710 ft). The Großer Feldberg is located in its immediate neighbourhood. In 1913, a meteorological and geophysical observatory was built there by German meteorologist Franz Linke. In 1988 an astronomical observatory was built on the mountain's top. The source of

80-773: A balanced climate. The Hintertaunus is divided into the Western and Eastern Hintertaunus by the Idstein Depression, which developed in the Idstein – Bad Camberg area. The Idstein depression widens towards the Lahn valley towards the Limburg Basin and is also known as the Goldener Grund in the northern area, probably because agriculture found more favorable conditions here. The relief is gently undulating,

120-509: A famous debate , which is said to exemplify the two major deviations in biological thinking at the time – whether animal structure was due to function or evolution. Most taxa differ morphologically from other taxa. Typically, closely related taxa differ much less than more distantly related ones, but there are exceptions to this. Cryptic species are species which look very similar, or perhaps even outwardly identical, but are reproductively isolated. Conversely, sometimes unrelated taxa acquire

160-649: A significant contribution to Wiesbaden's water supply. The largest unit of the Taunus in terms of area, the Hintertaunus unit, is mainly composed of the black rock series of the Hunsrück slate and the Singhofen layers of the lower Ems tier, often greywacke-like sandstones as well as siltstone and claystone . Younger rocks are only exposed here in small occurrences near Usingen and on the very eastern edge of

200-529: A similar appearance as a result of convergent evolution or even mimicry . In addition, there can be morphological differences within a species, such as in Apoica flavissima where queens are significantly smaller than workers. A further problem with relying on morphological data is that what may appear morphologically to be two distinct species may in fact be shown by DNA analysis to be a single species. The significance of these differences can be examined through

240-415: Is a heterogeneous landscape area, but it is usually quite distinct from the surrounding landscapes and is classified as a main natural area unit group. The natural landscape is divided according to morphology , geological structure , climate and partly by the prevailing vegetation into sub-landscapes that are more uniform in themselves. The cultural landscape, i.e. the natural landscape shaped by man, shows

280-569: Is about 75 km long from southwest to northeast and about 35 km wide across it from northwest to southeast,it covers an area of about 2700 km . In the west, the Upper Middle Rhine Valley borders the Taunus and separates it from the western Hunsrück . In the north, the valley of the Lahn (Giessen-Koblenzer Lahntal ) with the Limburg Basin forms a very sharp scenic border to the northern Westerwald . In

320-679: Is composed of pure, mostly black mudstone and embedded sandstone banks and occurs in stratigraphically different positions in the Upper Siegen and in the Ems. The bulk of the Hunsrück Slate is attributed to the Elm Lower Stage . It is known for its exceptionally well-preserved fossils and is locally well suited for use as roofing slate . . In the western Hintertaunus, the almost sand-free Hunsrück slate can be easily separated from

360-431: Is why the climate here is rougher than in the upstream landscape areas - it is colder on average, it rains and, in particular, it snows more. The turbulent relief offers little space for settlements and agricultural use. On the mostly shallow and fertile soils , which developed from acidic rock , there is mainly forest here. The Vortaunus is more inconsistent than the main ridge, it is morphologically more fragmented and

400-690: The Bunte Schiefer are greenish-grey or strikingly violet in color due to finely distributed hematite . Agnaths (jawless fish) found in the Bunte Schist are from the Gedinne (Lochkovian); just like the formation of the rock , they show a deposit of the colorful slate in rivers or lakes . The rocks of the colorful slate are found on the Großer Feldberg , where they were mined in tunnels to extract roofing slate (slate tunnel below

440-738: The Eschbacher cliffs near Usingen are such a quartz vein ( Härtling ) exposed by erosion . This vein, also known as the Usinger quartz vein, can be traced over a length of about 12 km, making it one of the longest German quartz veins after the Bavarian Pfahl. The northwestern part of the Eastern Hintertaunus (Langhecker Lahntaunus) , which leads to the Weilburger Lahntalgebiet, belongs geologically to

The ore was mined in numerous mines here, as in the Montan area Lahn-Dill area ; some have been converted to visitor mines. The Mining that operated from

520-716: The Red Cross ). Quartzite sandstones are embedded in them, from which the Brunhildis rock on the summit of the Großer Feldberg consists. The Hermeskeil layers are exposed below the Großer Feldberg and consist of mudstones, weakly consolidated micaceous sandstones and quartzites of the Lower Siegen (Lower Pragian). They are covered by several 100 m thick layers of Taunus quartzite (Middle Siegen, Pragian/Emsian). The very weather-resistant rock forms many summits of

560-614: The Weil River and a small castle of the Limes Germanicus are located at its northern base. This Hesse location article is a stub . You can help Misplaced Pages by expanding it . Taunus The Taunus is a mountain range in Hesse , Germany , located north west of Frankfurt and north of Wiesbaden . The tallest peak in the range is Großer Feldberg at 878 m; other notable peaks are Kleiner Feldberg (825 m) and Altkönig (798 m). The Taunus range spans

600-537: The districts of Hochtaunuskreis , Main-Taunus-Kreis , Rheingau-Taunus , Limburg-Weilburg , and Rhein-Lahn . The range is known for its geothermal springs and mineral waters that formerly attracted members of the European aristocracy to its spa towns . The car line Ford Taunus is named after it. The Taunus is the southeastern part of the Rhenish Slate Mountains . The low mountain range

640-493: The stratigraphic sequences Graue Phyllite , Bunte Schiefer , Hermeskeilschichten and Taunusquarzit . The Lower Devonian sub-layer only appears in two small outcrops, metavolcanites of the type found in the Anterior Taunus rocks. The Graue Phyllite consist of slates and sandstones . They contain impressions of Upper Silurian brachiopods and corals and were deposited in shallow water . The clay slates of

680-411: The 17th to the 20th centuries has now ceased. In the eastern Taunus between Idstein in the west and Usingen in the east, from the late Middle Ages to the early 20th century, there was a large number of pits in which there was mining of varying intensity on post-varistic, i.e. only after the varistic orogeny ore veins formed in the late Jurassic and early Cretaceous. The last active lead and silver ore mine,

720-845: The Eppstein slates of the Silurian and the Lower Devonian Lorsbach slates . At the very southern edge and in a small deposit near Mühlbach in the east of the Vordertaunus unit, limestones are exposed that are attributed to the Middle Devonian . To the north of the Vordertaunus is the Taunuscrest, also known as the High Taunus, which mainly consists of Lower Devonian clastic rocks . It is composed of

760-612: The Giessen Nappe, which lies flat today, on rocks from the Hintertaunus and the Lahn Mulde is of even greater extent. Their rocks are not otherwise found in the Taunus, they must have been deposited south of the Vortaunus and were thrust at least 25 km over the Taunus and Hintertaunus, possibly significantly more due to large-scale considerations. In addition to the deformation of the layers, these are clearly metamorphic in

800-611: The Heftrich pit with the Hannibal and Hasdrubal tunnels, was closed around 1924. Exploration drilling carried out by the Hessian State Office for Soil Research in the 1980s no longer provided any indication of deposits worth building. Due to its hardness, the Taunus quartzite was often mined in the past, currently only one quarry near Köppern is in operation. Some limestone and diabase quarries are still in operation in

840-601: The Hintertaunus in the Oberkleen area. The geology of the Hintertaunus is not as well known as that of the Vortaunus and Hochtaunus in the south or that of the Lahnmulde in the north due to the often monotonous sandy and slate rocks that form only a few continuous reference horizons and provide hardly any index fossils . The Hunsrück slate refers to a rock facies occurring mainly in the Hunsrück and Hintertaunus, which

880-544: The Hintertaunus is generally more open. The landscape of the Hintertaunus is more inconsistent because of its different elevations. This is clearly evident in the eastern Hintertaunus. Here, for example, there is a high-altitude landscape with dense forest cover, a harsher climate and poor soil in the Pferdskopf-Bergland ; but also the Usinger basin , a gently undulating, open basin landscape with fertile soil and

920-494: The Lahn, the Taunus natural region has a share in the Lahn trough and the Giessen nappe . The Vordertaunus Unit is a narrow zone of weakly metamorphic rocks such as phyllites, greenschists and sericite gneisses .[5] They are appear greenish through chlorite and epidote . The starting products of these rocks were mudstones and volcanic rocks . The rock strata occurring in the Vordertaunus are divided from north to south into

960-480: The Lahnmulde and Dillmulde typical rocks of this time such as Schalstein , Massenkalk and deck diabase absent here. The greywacke occurring here and at other places in the eastern Hintertaunus cannot or can hardly be distinguished from the Carboniferous Kulm greywacke and are considered by some scientists to be the remains of the ' Viewed 'Giessen Ceiling . The strata of the Taunus were formed in

1000-542: The Taunus range are Bad Schwalbach (formerly Langenschwalbach ) mentioned in documents dating back to the 16th century, Bad Ems , one of the most reputed therapeutic spas in Germany since the 17th century, as well as Bad Weilbach , where a spring reached wide fame for some time. By the 19th century the most famous spa towns in the area were Wiesbaden , Bad Homburg vor der Höhe, Bad Nauheim , and Bad Soden am Taunus . Morphology (biology) This includes aspects of

1040-575: The Taunus ridge ( Altkönig , Kleiner Feldberg , Glaskopf ), but also individual rock elevations (such as the Hohle Stein ). The Celtic ring walls and the rubble heap on the "White Wall" on the Altkönig consist of Taunus quartzite. The fractured groundwater of the Taunus quartzite is of local interest for water extraction. They are dammed by the underlying Hermeskeilschichten and pumped through groundwater tunnels. Four such groundwater tunnels make

1080-546: The Vordertaunus – the latter clearly decreases to the north. In later uplift phases between the Late Jurassic and the Tertiary , cross-fractures were applied perpendicular to strike. The rift valley of the Idstein Depression divides the Hintertaunus into an eastern and western part, while the Limburg Basin divides the Lahn Mulde as it sinks. Some of the fractures are now filled with quartz . The free-standing rocks of

1120-512: The bays of the foothills divide it more. Hintertaunus is the name given to the area north of the Hoher Taunus up to the Lahn valley . The landscape here is lower and less mountainous than in the southern Taunus. Between the valleys, some of which are quite deep, there are pronounced plateaus (leveled areas) with heavy agricultural use. Since mostly only the slopes of the valley are forested,

1160-635: The course of the Variscan Orogonese foliated , scaled and in the southwest-northeast strike saddles and troughs folded. The folds are predominantly northwestvergent . Widespread to the northwest, the rock series were thrust onto younger ones. Thus, at the fault zone of the Taunuskamm overthrust , the entire length of the southern Taunus nappe-like was thrust over rocks of the Younger Lower Devonian. The overthrust of

1200-848: The east, the Giessen Basin (southernmost part of the West Hessian Uplands ) with Dießenbach and Kleebach border to the north, the Wetterau with Wetter and Nidda to the south of the slate mountains; in the south, the Rheingau and the Main-Taunus foothills form natural borders. The last three landscapes are part of the Rhine-Main lowlands. On the southern edge are the towns of Rüdesheim am Rhein , Wiesbaden , Hofheim am Taunus and Bad Homburg vor der Höhe at

1240-598: The following structure in terms of land use, the location and distribution of settlements and the course of traffic routes. In the south are the more wooded and higher parts, namely the Vordertaunus (naturally also called Vortaunus) and the Hohe Taunus (around Taunus main ridge ), where in the Feldberg massif the highest heights not only of the Taunus but of the entire Rhenish Slate Mountains are reached. That

The Taunus

1320-652: The metavolcanic sequence, the Eppstein slate and the Lorsbach slate. The oldest sedimentary rocks of the Taunus are the phyllites of Bierstadt from the lower Ordovician era, known only from a borehole in Wiesbaden , with an age of about 480 million years determined by the evidence of spores . The volcanic rocks of the metavulcanite unit are younger, they could be dated to the Upper Ordovician and Silurian using uranium-lead dating . They are overlaid by

1360-465: The outward appearance (shape, structure, color, pattern, size), i.e. external morphology (or eidonomy ), as well as the form and structure of internal parts like bones and organs , i.e. internal morphology (or anatomy ). This is in contrast to physiology , which deals primarily with function. Morphology is a branch of life science dealing with the study of the gross structure of an organism or taxon and its component parts. The etymology of

1400-523: The part of the Lahnmulde that belongs to the Taunus. In addition, there are countless smaller quarries to supply the local population with building blocks. The Roman Limes was built across the Taunus. The Saalburg , a restored Roman castellum, now houses a museum. After the fall of the Limes (in 259/260 AD), the Alamanni settled in the range and for this reason there are some Alemannic cemeteries in

1440-534: The sandy rocks of the Singhofen layers, in the east, rocks in the Facies of the Hunsrück slate recede. Transposed volcanic tuffes and ashes , the so-called porphyroides , are integrated into the Singhofen layers, they can be traced in some cases over several tens of kilometers. The Middle Devonian to Lower Carboniferous of the Usinger Mulde is only about 250 m thick and strongly tectonically disturbed, in

1480-416: The soil is fertile due to the high proportion of loess and the climate is milder due to the basin location. The Taunus (main unit group 30) is subdivided in terms of natural space as follows: The Taunus is geologically divided from south to north into the units Vordertaunus unit (also northern phyllite zone or metamorphic southern edge zone), Taunus ridge unit and Hintertaunus unit. Finally, south of

1520-544: The southern foothills of the Taunus ( Eschborn ). This area of the Taunus became part of the Frankish confederation of Germanic tribes after the Battle of Tolbiac around 500 AD. In past centuries the Taunus became famous among aristocrats for its therapeutic hot springs . Certain towns in the area, such as Bad Homburg vor der Höhe with its Kurpark , have geothermal spas that were formerly renowned. Other spa towns in

1560-576: The use of allometric engineering in which one or both species are manipulated to phenocopy the other species. A step relevant to the evaluation of morphology between traits/features within species, includes an assessment of the terms: homology and homoplasy . Homology between features indicates that those features have been derived from a common ancestor. Alternatively, homoplasy between features describes those that can resemble each other, but derive independently via parallel or convergent evolution . The invention and development of microscopy enabled

1600-774: The word "morphology" is from the Ancient Greek μορφή ( morphḗ ), meaning "form", and λόγος ( lógos ), meaning "word, study, research". While the concept of form in biology, opposed to function , dates back to Aristotle (see Aristotle's biology ), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach (1800). Among other important theorists of morphology are Lorenz Oken , Georges Cuvier , Étienne Geoffroy Saint-Hilaire , Richard Owen , Carl Gegenbaur and Ernst Haeckel . In 1830, Cuvier and Saint-Hilaire engaged in
