Bolivian Orocline
An orocline — from the Greek words for "mountain" and "to bend" — is a bend or curvature of an orogenic (mountain building) belt imposed after it was formed. The term was introduced by S. Warren Carey in 1955 in a paper setting forth how complex shapes of various orogenic belts could be explained by actual bending, and that understanding this provided "the key to understanding the evolution of the continents". Carey showed that in a dozen cases where such bends were undone the results were substantially identical with continental reconstructions deduced by other means. Recognition of oroclinal bending provided strong support to the subsequent theory of plate tectonics. Examples *The Bolivian Orocline is a seaward concave bending in the coast of South America and the Andes mountains at about 18° S. At this point the orientation of the Andes turns from Northwest in Peru to South in Chile and Argentina. The Andean segment north and south of the orocline have been rotated 15° t ...

Orogeny
Orogeny () is a mountain-mountain formation, building process that takes place at a convergent boundary, convergent plate margin when plate motion compresses the margin. An or develops as the compressed plate crumples and is tectonic uplift, uplifted to form one or more mountain ranges. This involves a series of geological processes collectively called orogenesis. These include both structural deformation (physics), deformation of existing continental crust and the creation of new continental crust through volcanism. Magma rising in the orogen carries less dense material upwards while leaving more dense material behind, resulting in compositional differentiation of Earth's lithosphere (crust (geology), crust and uppermost mantle (geology), mantle). A synorogenic (or synkinematic) process or event is one that occurs during an orogeny. The word ''orogeny'' comes . Although it was used before him, the American geologist Grove Karl Gilbert, G. K. Gilbert used the term in 1890 to me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Syntaxis (geology)
A syntaxis is an abrupt major change in the dominant orientation of the main fold and thrust structures in an orogenic belt. For example, the Himalayan belt forms a continuous gentle curve in its main part, running almost perpendicular to the motion of the Indian Plate as it collides with the Eurasian Plate. This thrust-dominated plate boundary connects at both ends to the highly oblique, strike-slip In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic ... dominated boundaries running through Pakistan and Myanmar, forming the Nanga Parbat syntaxis to the west and the Namche Barwa syntaxis in the east.

Lapland Granulite Belt
The Lapland Granulite Belt is an elongate and arcuate zone of granulite rock in the Cap of the North spanning areas within Norway, Finland and Murmansk Oblast in Russia. At most the belt is 80 km broad. The main rocks of the belt are migmatized greywacke and argillites. Studies of detrital zircon show that the sedimentary protolith of the metamorphic rocks of the belt could not be older than 2900–1940 million years. The belt has norite and enderbite intrusions of calc-alkaline chemistry. It is believed that the belt formed by the closure of an ancient Lapland-Kola Ocean and the continental collision of two continents of Archean age. The granulite belt with its arcuate shape is part of the larger Inari orocline. This orocline include also the Tana and Karasjok belts. Two ideas on origin of the orocline have been proposed; that it originated at the same time as the southwest directed thrusting Thrust is a reaction force described quantitatively by Newton's third law.

Svecofennian Orogeny
The Svecofennian orogeny is a series of related orogenies that resulted in the formation of much of the continental crust in what is today Sweden and Finland along with minor parts of Russia, mainly within what is today the Republic of Karelia. The orogenies lasted from about 2000 to 1800 million years ago during the Paleoproterozoic Era. The resulting orogen is known as the Svecofennian orogen or Svecofennides. To the west and southwest the Svecofennian orogen limits with the generally younger Transscandinavian Igneous Belt. It is assumed that the westernmost fringes of the Svecofennian orogen have been reworked by the Sveconorwegian orogeny just as the western parts of the Transscandinavian Igneous Belt has. The Svecofennian orogeny involved the accretion of numerous island arcs in such manner that the pre-existing craton grew with this new material from what is today northeast to the southwest. The accretion of the island arcs was also related to two other processes th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alps
The Alps () are some of the highest and most extensive mountain ranges in Europe, stretching approximately across eight Alpine countries (from west to east): Monaco, France, Switzerland, Italy, Liechtenstein, Germany, Austria and Slovenia. The Alpine arch extends from Nice on the western Mediterranean Sea, Mediterranean to Trieste on the Adriatic Sea, Adriatic and Vienna at the beginning of the Pannonian Basin. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrust fault, thrusting and Fold (geology), folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the French–Italian border, and at is the highest mountain in the Alps. The Alpine region area contains 82 peaks higher than List of Alpine four-thousanders, .

Calabria
Calabria is a Regions of Italy, region in Southern Italy. It is a peninsula bordered by the region Basilicata to the north, the Ionian Sea to the east, the Strait of Messina to the southwest, which separates it from Sicily, and the Tyrrhenian Sea to the west.

They established the first cities, mainly on the coast, as Greek colonisation, Greek colonies. During this period Calabria was the heart of Magna Graecia, home of key figures in history such as Pythagoras, Herodotus and Milo of Croton, Milo.

Apennines
The Apennines or Apennine Mountains ( ; or Ἀπέννινον ὄρος; or – a singular with plural meaning; )Latin ''Apenninus'' (Greek or ) has the form of an adjective, which would be segmented ''Apenn-inus'', often used with nouns such as ("mountain") or Greek (), but ''Apenninus'' is just as often used alone as a noun. The ancient Greeks and Romans typically but not always used "mountain" in the singular to mean one or a range; thus, "the Apennine mountain" refers to the entire chain and is translated "the Apennine mountains". The ending can vary also by gender depending on the noun modified. The Italian singular refers to one of the constituent chains rather than to a single mountain, and the Italian plural refers to multiple chains rather than to multiple mountains. are a mountain range consisting of parallel smaller chains extending the length of peninsular Italy.

Gibraltar ( , ) is a British Overseas Territories, British Overseas Territory and British overseas cities, city located at the southern tip of the Iberian Peninsula, on the Bay of Gibraltar, near the exit of the Mediterranean Sea into the Atlantic Ocean (Strait of Gibraltar). It has an area of and is Gibraltar–Spain border, bordered to the north by Spain (Campo de Gibraltar).
