Palmyrides Mountain Belt
The Palmyra fold belt forms fold mountains found mostly in Syria. The mountains are formed due to thrusting together of Aleppo plateau in the north and Rubtah uplift in the south. This is according to the modern theory of plate tectonics. Similar view of the feature from the geosyncline theory can be taken where Palmyra can be viewed as Median mass between the two forelands of Aleppo foreland )), is an adjective which means "white-colored mixed with black". , motto = , image_map = , mapsize = , map_caption = , image_map1 = ... in the north and Rubtah foreland in the south.

Fold Mountains
Fold mountains are formed by the effects of folding on layers within the upper part of the Earth's crust. Before the development of the theory of plate tectonics and before the internal architecture of thrust belts became well understood, the term was used to describe most mountain belts but has otherwise fallen out of use. Formation Fold mountains form in areas of thrust tectonics, such as where two tectonic plates move towards each other at convergent plate boundary. When plates and the continents riding on them collide or undergo subduction (that is – ride one over another), the accumulated layers of rock may crumple and fold like a tablecloth that is pushed across a table, particularly if there is a mechanically weak layer such as salt. Since the less dense continental crust "floats" on the denser mantle rocks beneath, the weight of any crustal material forced upward to form hills, plateaus or mountains must be balanced by the buoyancy force of a much greater volume f ...

Syria
Syria ( ar, سُورِيَا or سُورِيَة, translit=Sūriyā), officially the Syrian Arab Republic ( ar, الجمهورية العربية السورية, al-Jumhūrīyah al-ʻArabīyah as-Sūrīyah), is a Western Asian country located in the Eastern Mediterranean and the Levant. It is a unitary republic that consists of 14 governorates (subdivisions), and is bordered by the Mediterranean Sea to the west, Turkey to the north, Iraq to the east and southeast, Jordan to the south, and Israel and Lebanon to the southwest. Cyprus lies to the west across the Mediterranean Sea. A country of fertile plains, high mountains, and deserts, Syria is home to diverse ethnic and religious groups, including the majority Syrian Arabs, Kurds, Turkmens, Assyrians, Armenians, Circassians, Albanians, and Greeks. Religious groups include Muslims, Christians, Alawites, Druze, and Yazidis. The capital and largest city of Syria is Damascus. Arabs are the largest ethnic group, and Mu ...

Aleppo Plateau
The Aleppo plateau ( ar, هضبة حلب ) is a low, gently undulating plateau of northern Syria. It lies at the northern end of the junction between the Arabian Plate and the African Plate at the Dead Sea Rift. The plateau lies mostly in the Aleppo Governorate and Idlib Governorate. Aleppo is located in the north-center of the plateau. Boundaries The Aleppo plateau lies immediately north of the Palmyra mountain belt. To the east it is bounded by the Euphrates river valley, which separates it from the Jazirah plateau. To the west it is bounded by the northern half of the Dead Sea Rift, namely the Orontes river valley. The Aintab plateau forms a northern continuation of the plateau that leads to the Taurus Mountains. Description The average elevation of the plateau is 400 m. The surface gradually slopes down in north-south and west-east directions. The surface undulates gently with an amplitude of 10–30 m for each wave. The lowlands are covered with combined Paleozoic an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plate Tectonics
Plate tectonics (from the la, label=Late Latin, tectonicus, from the grc, τεκτονικός, lit=pertaining to building) is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago. The model builds on the concept of ''continental drift'', an idea developed during the first decades of the 20th century. Plate tectonics came to be generally accepted by geoscientists after seafloor spreading was validated in the mid to late 1960s. Earth's lithosphere, which is the rigid outermost shell of the planet (the crust and upper mantle), is broken into seven or eight major plates (depending on how they are defined) and many minor plates or "platelets". Where the plates meet, their relative motion determines the type of plate boundary: '' convergent'', '' divergent'', or ''transform''. Earthquakes, volcanic activity, mountain-building, and oceanic tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geosyncline
A geosyncline (originally called a geosynclinal) is an obsolete geological concept to explain orogens, which was developed in the late 19th and early 20th centuries, before the theory of plate tectonics was envisaged. Şengör (1982), p. 11 A geosyncline was described as a giant downward fold in the Earth's crust, with associated upward folds called geanticlines (or geanticlinals), that preceded the climax phase of orogenic deformation. History The geosyncline concept was first conceived by the American geologists James Hall and James Dwight Dana in the mid-19th century, during the classic studies of the Appalachian Mountains. Émile Haug further developed the geosyncline concept, and introduced it to Europe in 1900. Şengör (1982), p. 26 Eduard Suess, a leading geologist of his time, disapproved the concept of geosyncline, and in 1909 he argued against its use due to its association with outdated theories. Şengör (1982), p. 43 This did not prevent further development of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palmyra
Palmyra (; Palmyrene: () ''Tadmor''; ar, تَدْمُر ''Tadmur'') is an ancient city in present-day Homs Governorate, Syria. Archaeological finds date back to the Neolithic period, and documents first mention the city in the early second millennium BC. Palmyra changed hands on a number of occasions between different empires before becoming a subject of the Roman Empire in the first century AD. The city grew wealthy from trade caravans; the Palmyrenes became renowned as merchants who established colonies along the Silk Road and operated throughout the Roman Empire. Palmyra's wealth enabled the construction of monumental projects, such as the Great Colonnade, the Temple of Bel, and the distinctive tower tombs. Ethnically, the Palmyrenes combined elements of Amorites, Arameans, and Arabs. The city's social structure was tribal, and its inhabitants spoke Palmyrene Aramaic, a variety of Western Middle Aramaic, while using Koine Greek for commercial and diplomatic purposes. ...
