Aladagh Mountains
The Aladagh Mountains or the Aladagh Range refers to a mountain range situated in the southeastern section of North Khorasan Province in the northeastern part of Iran southeast of the Caspian Sea. The range is located almost 25 kilometres south of Bojnurd, the capital city of North Khorasan. The Aladagh Mountains merge with the Elburz or Alborz Mountains in the west and then run southeastwards in a northwest-southeast direction. The highest peak of the range is Mount Shahjahan with an elevation of 3032 metres. This peak is located about 35 kilometres east of Esfarayen almost in southeastern part of North Khorasan Province. Etymology Linguistically, the word ''Aladagh'' comes from the Turkic branch of the Altaic language family (- and, more specifically, from the Khorasani Turkic language ) and consists of two parts, ''ala'' and ''dagh'' /''dag''. ''Ala'' means "variegated", "patchwork", "particoloured " or "speckled" and ''dagh'' means "mountain", and therefore the word ''A ...

The Brack
The Brack is a mountain, located in the Arrochar Alps, on the south side of Glen Croe, near Loch Goil in Argyll and Bute in Scotland. The Brack has two summits: the lower peak, Cruach Fhiarach, can be seen from the shores of Loch Long, and the main peak is seen from Glen Croe and Loch Goil. The Brack is in the Ardgoil range, which is located on a peninsula bounded on the west by Loch Goil and Loch Long on the east, both lochs being arms of the Firth of Clyde. The Brack is connected by ridges to Ben Donich and Cnoc Coinnich, and is surrounded by a number of higher peaks. It is classified as a Corbett. The Loch Lomond and Cowal Way passes to the south of the peak, over the bealach separating The Brack from Cnoc Coinnich.Ordnance Survey Landranger (1:50000) Series. Sheet 56.

Mountain Ranges Of Iran
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Kopet-Dag
The Köpet Dag, Kopet Dagh, or Koppeh Dagh ( tk, Köpetdag; fa, کپهداغ), also known as the Turkmen-Khorasan Mountain Range, is a mountain range on the border between Turkmenistan and Iran that extends about along the border southeast of the Caspian Sea, stretching northwest-southeast from near the Caspian Sea in the northwest to the Harirud River in the southeast. In the southwest it borders on the parallel eastern endings of the Alborz mountains being together part of the much larger Alpide belt. The highest peak of the range in Turkmenistan is the Mount Rizeh (Kuh-e Rizeh), located at the southwest of the capital Ashgabat and stands at . The highest Iranian summit is Mount Quchan (Kuh-e Quchan) with . Etymology Vambery conjectured that ''köpet'' originates from the Turkmen language where "köp" means "a lot" or "many" and the word "dag" means "mountain" or "peak". He thus translated Köpetdag as "Many mountains (peaks)". He and others noted that in Persian ''koppeh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binalud Mountains
The Binalud Mountain Range or the Binalud Range ( fa, بینالود - ''Bīnālūd'') is a mountain range that runs in a northwest-southeast direction between the Nishapur and Mashhad regions in Razavi Khorasan Province in northeastern Iran, to the southeast of the Caspian Sea. Although far from the Aladagh Mountains, which lie to the northwest in the Province of North Khorasan, the Binalud Mountains are located in such a way that both the Aladagh Mountains and the Binalud Range lie approximately in the same arc, curving from the northwest to the southeast. The city of Mashhad or Meshed is located in the northeastern part of the Binalud Range, and the city of Nishapur or Neyshabur lies on the southwestern section of the range. Situated somewhat to the west of the Binalud Range proper, and with an elevation of 3211 metres, Mount Binalud is the highest point both of the Binalud Mountains and of Razavi Khorasan Province as a whole.

Paleozoic
The Paleozoic (or Palaeozoic) Era is the earliest of three geologic eras of the Phanerozoic Eon. The name ''Paleozoic'' ( ;) was coined by the British geologist Adam Sedgwick in 1838 by combining the Greek words ''palaiós'' (, "old") and ''zōḗ'' (), "life", meaning "ancient life" ). It is the longest of the Phanerozoic eras, lasting from , and is subdivided into six geologic periods (from oldest to youngest): # Cambrian # Ordovician # Silurian # Devonian # Carboniferous # Permian The Paleozoic comes after the Neoproterozoic Era of the Proterozoic Eon and is followed by the Mesozoic Era. The Paleozoic was a time of dramatic geological, climatic, and evolutionary change. The Cambrian witnessed the most rapid and widespread diversification of life in Earth's history, known as the Cambrian explosion, in which most modern phyla first appeared. Arthropods, molluscs, fish, amphibians, reptiles, and synapsids all evolved during the Paleozoic. Life began in the oc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jurassic
The Jurassic ( ) is a geologic period and stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and is the only boundary between geological periods to remain formally undefined. By the beginning of the Jurassi ...

Pliocene
The Pliocene ( ; also Pleiocene) is the epoch in the geologic time scale that extends from 5.333 million to 2.58See the 2014 version of the ICS geologic time scale million years ago. It is the second and most recent epoch of the Neogene Period in the Cenozoic Era. The Pliocene follows the Epoch and is followed by the Epoch. Prior to the 2009 revision of the geologic time sca ...

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. ...

Neogene
The Neogene ( ), informally Upper Tertiary or Late Tertiary, is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago ( Mya) to the beginning of the present Quaternary Period Mya. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary. The term "Neogene" was coined in 1853 by the Austrian palaeontologist Moritz Hörnes (1815–1868). During this period, mammals and birds continued to evolve into modern forms, while other groups of life remained relatively unchanged. The first humans ('' Homo habilis'') appeared in Africa near the end of the period. Some continental movements took place, the most significant event being the connection of North America, North and South America at the Isthmus of Panama, late in the Pliocene. This cut off the warm ocean currents from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
