Fergana Valley
The Fergana Valley (; ; ) in Central Asia lies mainly in eastern Uzbekistan, but also extends into southern Kyrgyzstan and northern Tajikistan. Divided into three republics of the former Soviet Union, the valley is ethnically diverse and in the early 21st century was the scene of conflict. A large triangular valley in what is an often dry part of Central Asia, the Fergana owes its fertility to two rivers, the Naryn and the Kara Darya, which run from the east, joining near Namangan, forming the Syr Darya river. The valley's history stretches back over 2,300 years, when Alexander the Great founded Alexandria Eschate at its southwestern end. Chinese chroniclers date its towns to more than 2,100 years ago, as a path between Greek, Chinese, Bactrian and Parthian civilisations. It was home to Babur, founder of the Mughal Dynasty, tying the region to modern Afghanistan and South Asia. The Russian Empire conquered the valley at the end of the 19th century, and it became part of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diabase
Diabase (), also called dolerite () or microgabbro, is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine-grained to aphanitic chilled margins which may contain tachylite (dark mafic glass). ''Diabase'' is the preferred name in North America, while ''dolerite'' is the preferred name in the rest of the English-speaking world, where sometimes the name ''diabase'' refers to altered dolerites and basalts. Some geologists prefer to avoid confusion by using the name ''microgabbro''. The name ''diabase'' comes from the French ', and ultimately from the Greek - meaning "act of crossing over, transition". Petrography Diabase normally has a fine but visible texture of euhedral lath-shaped plagioclase crystals (62%) set in a finer matrix of clinopyroxene, typically augite (20–29%), with minor olivine (3% up to 12% in olivine diabase), magnetite (2 ...

Gabbro
Gabbro () is a phaneritic (coarse-grained), mafic intrusive igneous rock formed from the slow cooling of magnesium-rich and iron-rich magma into a holocrystalline mass deep beneath the Earth's surface. Slow-cooling, coarse-grained gabbro is chemically equivalent to rapid-cooling, fine-grained basalt. Much of the Earth's oceanic crust is made of gabbro, formed at mid-ocean ridges. Gabbro is also found as plutons associated with continental volcanism. Due to its variant nature, the term ''gabbro'' may be applied loosely to a wide range of intrusive rocks, many of which are merely "gabbroic". By rough analogy, gabbro is to basalt as granite is to rhyolite. Etymology The term "gabbro" was used in the 1760s to name a set of rock types that were found in the ophiolites of the Apennine Mountains in Italy. It was named after Gabbro, a hamlet near Rosignano Marittimo in Tuscany. Then, in 1809, the German geologist Christian Leopold von Buch used the term more restrictively in his ...

Pamir-Alay
The Pamir-Alay (also ''Pamiro-Alay'', russian: Памиро-Алай) is a mountain system in Tajikistan, Kyrgyzstan and Uzbekistan, encompassing four main mountain ranges extending west from the Tian Shan Mountains, and located north of the main range of Pamir. They are variously considered part of the Tian Shan, of the Pamir, or a separate mountain system. The term "Pamiro-Alay" is also used to refer to the mountain region encompassing the Pamir, the Pamir-Alay proper (then referred to as "Gissaro-Alay") and the Tajik Depression.Гиссаро-Алай The Pamir-Alay stretches between the valleys of the rivers |
Söök Pass (Naryn Region)
Seok Pass, Söök Pass or Suyak Pass (russian: перевал Сёок, ky, Сөөк ашуусу) is a mountain pass in the Terskey Alatau mountain range of Kyrgyzstan. Its elevation of makes it the third highest mountain pass in Kyrgyzstan after Bedel Pass and Kyzylart Pass, and the highest one that is not on a border. It connects the Ala-Bel plateau, where the Kumtor Gold Mine is located, to the upper Naryn River valley. Seok Pass is situated on the ancient Silk Road route connecting Barskon on Lake Issyk-Kul and Kashgar in China's Xinjiang province across the Tian Shan mountains. It is one of three major passes on this route, located between Barskoon Pass (elevation ) and Bedel Pass (elevation ). As the border road over Bedel Pass to China has remained closed since Soviet times, Seok Pass is nowadays significant mainly as a strategic gateway on the A364 road to the southeastern high mountain desert areas of Kyrgyzstan along the Chinese border, and to the border posts at ...

Torugart Ridge
Torugart Pass (; ; ) is a mountain pass in the Tian Shan mountain range near the border between the Naryn Region of Kyrgyzstan and the Xinjiang Autonomous Region of China. It is one of two border crossings between Kyrgyzstan and China, the other being Erkeshtam, some 165 km (103 mi) to the southwest. The scenic lake Chatyr-Köl lies near the pass on the Kyrgyz side. The road to Naryn and then to Balykchy and Bishkek—stretching for some —is narrow and in winter often impassable due to heavy snowfall and frequent avalanches. On the Chinese side, the Torugart Port of Entry (吐尔尕特口岸), where travelers must clear for customs, is located about from the pass itself in Ulugqat County of the Kizilsu Kirghiz Autonomous Prefecture. Distances from the pass to major cities are: to Ulugqat, to Kashgar, to Artux and some to Ürümqi. The pass is also terminus of European route E125 and, under the new National Highway plans, the China National Highway 315 ...

The highest peak in the Tian Shan is Jengish Chokusu, at high. Its lowest point is the Turpan Depression, which is below sea level. One of the earliest historical references to these mountains may be related to the Xiongnu word ''Qilian'' ( zh, s=祁连, t=祁連, first=t, p=Qílián) – according to Tang commentator Yan Shigu, ''Qilian'' is the Xiongnu word for sky or heaven. Sima Qian in the ''Records of the Grand Historian'' mentioned ''Qilian'' in relation to the homeland of the Yuezhi and the term is believed to refer to the Tian Shan rather than the ...

Schist
Schist ( ) is a medium-grained metamorphic rock showing pronounced schistosity. This means that the rock is composed of mineral grains easily seen with a low-power hand lens, oriented in such a way that the rock is easily split into thin flakes or plates. This texture reflects a high content of platy minerals, such as micas, talc, chlorite, or graphite. These are often interleaved with more granular minerals, such as feldspar or quartz. Schist typically forms during regional metamorphism accompanying the process of mountain building ( orogeny) and usually reflects a medium grade of metamorphism. Schist can form from many different kinds of rocks, including sedimentary rocks such as mudstones and igneous rocks such as tuffs. Schist metamorphosed from mudstone is particularly common and is often very rich in mica (a ''mica schist''). Where the type of the original rock (the protolith) is discernible, the schist is usually given a name reflecting its protolith, such as ''sch ...
