18-680: The range lies just west of the boundary of the Eurasian and the North American tectonic plates . The mountains were formed by folding , and represent an anticline . The Verkhoyansk Range was covered by glaciers during the Last Glacial Period and the mountains in the northern section, such as the Orulgan Range , display a typical Alpine relief. There are coal , silver , lead , tin , and zinc deposits in

36-726: Is a tectonic plate that includes most of Eurasia (a landmass consisting of the traditional continents of Asia and Europe ), with the notable exceptions of the Arabian Peninsula , the Indian subcontinent , and the area east of the Chersky Range in eastern Siberia . It also includes oceanic crust extending westward to the Mid-Atlantic Ridge and northward to the Gakkel Ridge . The western edge

54-464: Is a triple junction plate boundary with the North American plate and Nubian plate at the seismically active Azores triple junction extending northward along the Mid-Atlantic Ridge towards Iceland . Ridges like the Mid-Atlantic ridge form at a divergent plate boundary . They are located deep underwater and very difficult to study. Scientists know less about ocean ridges than they do

72-641: Is navigable. It has a drainage basin of 729,000 square kilometres (281,000 sq mi). The river was part of the River Route to Okhotsk . In 1639 Ivan Moskvitin ascended the rivers Aldan and Maya and crossed to the Ulya to reach the Sea of Okhotsk . Its basin is known for gold and for Cambrian fossils . Previously, a version of the origin from the Turkic-Mongolian word altan, altyn in

90-619: The Omoloy and Yana to the east and northeast. It is deeply cut by riverine intermontane basins . Many right tributaries of the Lena flow westwards, having their sources in the range, including the Kyundyudey , Undyulyung , Begidyan , Sobolokh-Mayan , Menkere , Dzhardzhan , Uel-Siktyakh , Kuranakh-Siktyakh , Byosyuke , Tikyan , Dyanyshka , Lyapiske , Belyanka , Munni , Kele , Tukulan , Tumara , Nuora , and Baray , among others. To

108-588: The 1783 eruption of Laki and the 2010 eruption of Eyjafjallajökull , are caused by the North American and the Eurasian plates moving apart, which is a result of divergent plate boundary forces. The convergent boundary between the Eurasian plate and the Indian plate formed the Himalayas mountain range. The geodynamics of Central Asia is dominated by the interaction between the Eurasian plate and

126-707: The Indian plate. In this area, many sub-plates or crust blocks have been recognized, which form the Central Asian and the East Asian transit zones. Aldan River The Aldan ( Sakha and Russian : Алдан ) is the second-longest right tributary of the Lena in the Sakha Republic in eastern Siberia . The river is 2,273 kilometres (1,412 mi) long, of which around 1,600 kilometres (990 mi)

144-771: The Verkhoyansk Mountain System. Bilibin and Bobin also explored for the first time the Yudoma-Maya Highlands , located to the southeast of the Ulakhan-Bom/Sette-Daban/Skalisty ranges. Besides the Orulgan, the system of the range comprises a number of subranges, as well as a plateau, including the following: The Verkhoyansk mountain system separates the basins of the Lena River to the west and southwest and

162-653: The boundary from the Nansen Ridge through a broad zone of deformation in North Asia to the Sea of Okhotsk then south through Sakhalin Island and Hokkaido to the triple junction in the Japan Trench . But this simple view has been successfully challenged by more recent research. During the 1970s, Japan was thought to be located on the Eurasian plate at a quadruple junction with the North American plate when

180-602: The east. The Verkhoyansk Range has a higher southeastern prolongation than the Suntar-Khayata Range , which is occasionally considered as a separate range system. Thus the highest point of the range in a restricted geographical sense is an unnamed 2,409-metre (7,904 ft)-high peak in the Orulgan Range . The Ulakhan-Bom , highest point 1,600 metres (5,200 ft), Sette-Daban , highest point 2,012 metres (6,601 ft), and Skalisty Range (Rocky Range), highest point 2,017 metres (6,617 ft), are located at

198-586: The eastern boundary of the North American plate was drawn through southern Hokkaido . New research in the 1990s supported that the Okhotsk microplate was independent from the North American plate and a boundary with the Amurian microplate , sometimes described as "a division within the Eurasian plate" with an unknown western boundary. All volcanic eruptions in Iceland, such as the 1973 eruption of Eldfell ,

216-659: The meaning of "gold" was spread, then a hypothesis appeared of the origin of the hydronym Aldan (in the variant Allan) from the Evenk oldo, ollo — "fish". Another explanation: aldan is a coastal spring ice ( evenk ). The Aldan rises in the Stanovoy Mountains southwest of Neryungri . It flows roughly in a northeast / ENE direction south of the Lena Plateau across the Aldan Highlands , where it forms

234-466: The mountainous areas are usually frozen between September and May. The world's lowest temperatures for inhabited places have been recorded in this region, and there is quite deep snow cover for most of the year. The mountain range is home to an alpine tundra , supporting various species of mosses and lichens. Some sparsely-wooded forests of mainly larch and dwarf Siberian pine are found on smooth slopes. Eurasian Plate The Eurasian plate

252-616: The mountains. Rising from the shores of the Buor-Khaya Gulf in the north, it runs southwards spanning roughly 1000 km (600 mi.) across Yakutia , east of the Central Yakutian Lowland , and west of the Chersky Range , reaching the Lena Plateau to the south and the Yudoma-Maya Highlands to the southeast. It forms a vast arc between the Lena and Aldan rivers to the west and the Yana River to

270-754: The northeast flow left tributaries of the Omoloy such as the Kuranakh-Yuryakh , Arga-Yuryakh , Bukhuruk , and Sietinde . The Tompo cuts across the range in its southern part, flowing from its source in the Suntar Khayata. The valley of the Aldan is located to the south, where the river makes a wide bend. From the eastern slopes flow the rivers Dulgalakh and Sartang , which form river Yana further north, as well as its tributaries Bytantay , Nelgese , Derbeke , and Baky , among others. Rivers in

288-580: The northern border of the Sunnagyn Range . Then it flows past Aldan and through Tommot , Ust-Maya , Eldikan and Khandyga before turning northwest. In its last stretch it flanks the southern slopes of the Verkhoyansk Range and joins the Lena near Batamay . The river's main tributaries are the following: This Sakha Republic location article is a stub . You can help Misplaced Pages by expanding it . This article related to

306-814: The planets of the solar system. There is another triple junction where the Eurasian plate meets the Anatolian sub-plate and the Arabian plate . The Anatolian sub-plate is currently being squeezed by the collision of the Eurasian plate with the Arabian plate in the East Anatolian Fault Zone . The boundary between the North American plate and the Eurasian plate in the area around Japan has been described as "shifty". There are different maps for it based on recent tectonics, seismicity and earthquake focal mechanism . The simplest plate geometry draws

324-553: The southern end and were also considered separate ranges in classical geographic works. The two ranges were surveyed in 1934 by geologist Yuri Bilibin (1901–1952) together with mining engineer Evgeny Bobin (1897–1941) in the course of an expedition sent by the government of the Soviet Union. After conducting the first topographic survey of the area, Bilibin established that the Skalisty and Sette-Daban mountain chains belong to
