Mountain Ranges, Deserts and Landforms of Turkmenistan

Geography

The lowland region lies to the east of the Caspian Sea and southeast of the Aral Sea in the vast Aral–Caspian Depression but extends to parts above sea level as well. It is one of the largest expanses of sand in the world, covering an area of around 3 million km2. On average, the region receives less than 15 inches (380 mm) of rainfall per year. The Karakum desert lies at the southern portion of the Turan Lowlands.

The part of the depression adjacent to the Aral Sea is drainless. It includes a network of temporary streams usually ending in sor salt flats, which seasonally become salt lakes.

Three of the largest cities in the Turan Depression are Daşoguz in Turkmenistan, Nukus in Uzbekistan, and Urganch, also in Uzbekistan. Akjagaýa in Turkmenistan is 267 feet (81 meters) below sea level.

Geography

The Ustyurt is located between the Dead Kultuk, Mangyshlak Peninsula and Kara-Bogaz-Gol of the Caspian Sea to the west, and the Aral Sea, Amudarya Delta and Sarygamysh Lake to the east.

It extends roughly 200,000 km2 (77,000 sq mi), with an average altitude of 150 m (490 ft). Its highest point rises to 370 m (1,200 ft) in the south-west. At its northeastern edge it drops steeply to the Aral Sea and the surrounding plain.

The Ustyurt Plateau is bounded by steep cliffs called chinks nearly from everywhere. To the east, it encompasses the historical western shoreline of the Aral Sea. In the southern region, it extends to the Kunya-Darya alluvial plain and the valley of the Uzboy, while in the west, it reaches the Karynyaryk depression.

Geology

Geologically, the Kopet Dag Range is made chiefly of Lower Cretaceous sedimentary rocks with a smaller portion of Jurassic rocks in the southeastern parts. The mountains were formed in the Miocene and the Pliocene during the Alpine orogeny. As the Tethys Sea was closed and the Arabian plate collided with the Iranian plate and was pushed against it and with the clockwise movement of the Eurasian plate towards the Iranian plate and their final collision, the Iranian plate was pressed against the Turan Platform. This collision folded the entire rocks that had been deposited in this geosyncline or basin from the Jurassic to the Miocene and formed the Kopet Dag Mountains.

Geography

Kyzylkum is mainly located in Uzbekistan. Its territory consists mainly of an extensive plain at an altitude up to 300 m (980 ft) above sea level, with a number of depressions and highlands (Sultanuizdag, Bukantau). Most of the area is covered with dunes (barchans); in the northwest large areas are covered with takirs (clay coatings); there are also some oases. There are agricultural settlements along the rivers and in the oases. Temperatures can be very high during the summer months, from mid-May to mid-September. Kerki, one extreme inland city located on the banks of the Amu Darya River, recorded 52 °C (126 °F) in July 1983.

Economy

The local population uses the large spaces of the Kyzylkum Desert as a pasture for livestock (mostly sheep, Bactrian camels and dromedaries).

The desert is well known for its deposits of gold, uranium, copper, aluminium and silver, natural gas and oil. The development of the most famous gold-field at Muruntau began in the early 1970s. The centres for the mining and smelting industry at the region are Navoi, Zarafshan, Uchkuduk. The major industrial enterprises are: НГМК (Navoi Mining and Smelting Complex) and the Uzbek U.S.A. Joint Venture "Zarafshan-Newmont". The centres of the gas-production industry are Gazli and Mubarek.

Geography

The desert covers roughly seventy percent of Turkmenistan, a long east–west swath. It sits east of the Caspian Sea which has a steep east bank. It adjoins, to the north, the long delta feeding the South Aral Sea further north, another endorheic lake, about 58 m (190 ft) higher than the Caspian Sea. The delta is that of the Amu Darya river to the northeast, demarcating the long border with the Kyzylkum Desert of Uzbekistan. The desert is divided into three regions, the elevated northern Trans-Unguz Karakum, the low-lying Central Karakum, and the southeastern Karakum, home to a chain of salt marshes. Since the early 1980s, the relatively small desert extension, the Aralkum, has come to occupy most of the former seabed of the Aral Sea, about 15,440 sq mi (40,000 km2).

Geology

The Karakum is home to the Darvaza gas crater. Also called the "Door to Hell" or the "Gates of Hell" by locals, it is a crater of natural gas that has been burning since 1971. The crater is a major tourist attraction, with hundreds of visitors arriving each year.
