Alay Mountains
The Alay or Alai Range (; ) is a mountain range that extends from the Tien Shan mountain range in Kyrgyzstan west into Tajikistan. It is part of the Pamir-Alay mountain system. The range runs approximately east to west. Its highest summit is Pik Tandykul (), reaching 5544 m. It forms the southern border of the Fergana Valley, and in the south it falls steeply to the Alay Valley.

Kyrgyzstan
Kyrgyzstan, officially the Kyrgyz Republic, is a landlocked country in Central Asia lying in the Tian Shan and Pamir Mountains, Pamir mountain ranges. Bishkek is the Capital city, capital and List of cities in Kyrgyzstan, largest city. Kyrgyzstan is bordered by Kazakhstan to the Kazakhstan–Kyrgyzstan border, north, Uzbekistan to the Kyrgyzstan–Uzbekistan border, west, Tajikistan to the Kyrgyzstan–Tajikistan border, south, and China to the China–Kyrgyzstan border, east and southeast. Ethnic Kyrgyz people, Kyrgyz make up the majority of the country's over 7 million people, followed by significant minorities of Uzbeks and Russians. Kyrgyzstan's history spans a variety of cultures and empires. Although geographically isolated by its highly mountainous terrain, Kyrgyzstan has been at the crossroads of several great civilizations as part of the Silk Road along with other commercial routes. Inhabited by a succession of tribes and clans, Kyrgyzstan has periodically fallen unde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andijan
Andijan ( ), also spelt Andijon () and formerly romanized as Andizhan ( ), is a city in Uzbekistan. It is the administrative, economic, and cultural center of Andijan Region. Andijan is a district-level city with an area of . Andijan is the most densely populated city with density of 10,000 people/km2 and it had 747,800 inhabitants in 2024. Andijan is located in a tense border region at the south-eastern edge of the Fergana Valley near Uzbekistan's border with Kyrgyzstan. At more 2,500 years in age, Andijan is the oldest city in Uzbekistan and one of the oldest cities in the Fergana Valley. In some parts of the city, archeologists have found items dating back to the 7th and 8th centuries Common Era, B.C.E. Historically, Andijan was an important city on the Silk Road. The city is perhaps best known as the birthplace of Babur who, following a series of setbacks, finally succeeded in laying the basis for the Mughal dynasty in the Indian subcontinent and became the first Mughal emp ...

Carboniferous
The Carboniferous ( ) is a Geologic time scale, geologic period and System (stratigraphy), system of the Paleozoic era (geology), era that spans 60 million years, from the end of the Devonian Period Ma (million years ago) to the beginning of the Permian Period, Ma. It is the fifth and penultimate period of the Paleozoic era and the fifth period of the Phanerozoic eon (geology), eon. In North America, the Carboniferous is often treated as two separate geological periods, the earlier Mississippian (geology), Mississippian and the later Pennsylvanian (geology), Pennsylvanian. The name ''Carboniferous'' means "coal-bearing", from the Latin ("coal") and ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern "system" names, it was coined by geologists William Conybeare (geologist), William Conybeare and William Phillips (geologist), William Phillips in 1822, based on a study of the British rock succession. Carboniferous is the per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devonian
The Devonian ( ) is a period (geology), geologic period and system (stratigraphy), system of the Paleozoic era (geology), era during the Phanerozoic eon (geology), eon, spanning 60.3 million years from the end of the preceding Silurian period at million years ago (Megaannum, Ma), to the beginning of the succeeding Carboniferous period at Ma. It is the fourth period of both the Paleozoic and the Phanerozoic. It is named after Devon, South West England, where rocks from this period were first studied. The first significant evolutionary radiation of history of life#Colonization of land, life on land occurred during the Devonian, as free-spore, sporing land plants (pteridophytes) began to spread across dry land, forming extensive coal forests which covered the continents. By the middle of the Devonian, several groups of vascular plants had evolved leaf, leaves and true roots, and by the end of the period the first seed-bearing plants (Pteridospermatophyta, pteridospermatophyt ...

Silurian
The Silurian ( ) is a geologic period and system spanning 23.5 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the third and shortest period of the Paleozoic Era, and the third of twelve periods of the Phanerozoic Eon. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods ( myriapods, arachnids and hexapods) ...

Variscan Orogeny
The Variscan orogeny, or Hercynian orogeny, was a geologic mountain-building event caused by Late Paleozoic continental collision between Euramerica (Laurussia) and Gondwana to form the supercontinent of Pangaea. Nomenclature The name ''Variscan'' comes from the Medieval Latin name for the district '' Variscia'', the home of a Germanic tribe, the Varisci; Eduard Suess, professor of geology at the University of Vienna, coined the term in 1880. ( Variscite, a rare green mineral first discovered in the Vogtland district of Saxony in Germany, which is in the Variscan belt, has the same etymology.) ''Hercynian'', on the other hand, derives from the Hercynian Forest. Both words were descriptive terms of strike directions observed by geologists in the field, ''variscan'' for southwest to northeast, ''hercynian'' for northwest to southeast. The ''variscan'' direction reflected the direction of ancient fold belts cropping out throughout Germany and adjacent countries and the meanin ...

Zarafshan Range
The Zarafshan Range, formerly the Zeravshan Range, is a mountain range in Tajikistan and Uzbekistan, part of the Pamir-Alay mountains. Almost all of the range belongs to the drainage basins of the Zarafshan River. The Persian name is believed to possibly be a reference to gold found in bed of the Zarafshan River and its tributaries, which has ushered prosperity to the region from ancient times. Geography and geology The range extends over in an east−west direction along the south of Sughd Region in Tajikistan, reaching the highest point of (Chimtarga Peak) in its central part. South-west of Panjakent the range crosses from Tajikistan into Uzbekistan, where it continues at decreasing elevations () along the internal border between Samarkand and Kashkadarya Regions provinces, until it blends into the desert south-west of Samarkand. There are two other mountain ranges running in an east−west direction parallel to the Zarafshan Range. To the north, the Zeravshan Valley ...

Pamir Mountains
The Pamir Mountains are a Mountain range, range of mountains between Central Asia and South Asia. They are located at a junction with other notable mountains, namely the Tian Shan, Karakoram, Kunlun Mountains, Kunlun, Hindu Kush and the Himalayas, Himalaya mountain ranges. They are among the world's highest mountains. Much of the Pamir Mountains lie in the Gorno-Badakhshan region of Tajikistan.

Trans-Alay Range
The Trans-Alay or Trans-Alai Range (, ; , , or , ; , ) is the northernmost range of the Pamir Mountain System. Following the collapse of the Soviet Union, the range has been divided between Tajikistan and Kyrgyzstan. Geography The Trans-Alay is located in the area where the Pamirs and the Tian Shan come together. This heavily glaciated range forms the border between the Gorno-Badakshan region in Tajikistan and the Osh Region, Kyrgyzstan, stretching eastwards until the border with China. The name was from the viewpoint of Russian explorers in the region: The Alay Range lies to the north of the Alay Valley, formed by the Kyzyl-Suu or upper Vakhsh River, one of the principal tributaries of the Amu Darya. The range on the far side of the valley, more distant from Russia and its outposts, became known as the Trans-Alay. The southern valley dividing the Trans-Alay from the Pamir proper is that of the river Muksu. Peaks The highest peak in the range is the 7134 m high Ibn Sina/L ...
