Eastern Sayan
The Sayan Mountains (, ; ) are a mountain range in southern Siberia spanning southeastern Russia (Buryatia, Irkutsk Oblast, Krasnoyarsk Krai, Tuva and Khakassia) and northern Mongolia. Before the rapid expansion of the Tsardom of Russia, the mountain range served as the border between Mongolian and Russian cultures and cultural influences. The Sayan Mountains' towering peaks and cool lakes southwest of Tuva give rise to the tributaries that merge to become one of Siberia's major rivers, the Yenisei River, which flows north over 3,400 kilometres (2000 mi) to the Arctic Ocean. This is a protected and isolated area, having been kept closed by the Soviet Union since 1944. Geography Western Sayan At 92°E the Western Sayan system is pierced by the Ulug-Khem () or Upper Yenisei River, and at 106°, at its eastern extremity, it terminates above the depression of the Selenga-Orkhon Valley. It stretches almost at a right angle to the Western Sayan for in a roughly northeast/south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angara
The Angara (; ) or Angar ( мүрэн) is a major river in Siberia, which traces a course through Russia's Irkutsk Oblast and Krasnoyarsk Krai. It drains out of Lake Baikal and is the headwater tributary of the Yenisey. It is long, and has a drainage basin of . It was formerly known as the Lower or Nizhnyaya Angara (distinguishing it from the Upper Angara). Below its junction with the Ilim, it was formerly known as the Upper Tunguska (, ''Verhnyaya Tunguska'', distinguishing it from the Lower Tunguska) and, with the names reversed, as the Lower Tunguska. Course Leaving Lake Baikal near the settlement of Listvyanka, the Angara flows north past the Irkutsk Oblast cities of Irkutsk, Angarsk, Bratsk, and Ust-Ilimsk. It then crosses the Angara Range and turns west, entering Krasnoyarsk Krai, and joining the Yenisey near Strelka, south-east of Lesosibirsk.

Drainage Basin
A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, " watershed" is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation, a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin, rather than flowing to the ocean, water converges toward the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nephrite
Nephrite is a variety of the calcium, magnesium, and iron-rich amphibole minerals tremolite or actinolite ( aggregates of which also make up one form of asbestos). The chemical formula for nephrite is Ca2( Mg, Fe)5 Si8 O22(O H)2. It is one of two different mineral species called jade. The other mineral species known as jade is jadeite, which is a variety of pyroxene. While nephrite jade possesses mainly grays and greens (and occasionally yellows, browns, black or whites), jadeite jade, which is rarer, can also contain blacks, reds, pinks and violets. Nephrite jade is an ornamental stone used in carvings, beads, or cabochon cut gemstones. Nephrite is also the official state mineral of Wyoming. Nephrite can be found in a translucent white to very light yellow form which is known in China as ''mutton fat'' jade, in an opaque white to very light brown or gray which is known as ''chicken bone'' jade, as well as in a variety of green colors. Western Canada is the principal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphite
Graphite () is a Crystallinity, crystalline allotrope (form) of the element carbon. It consists of many stacked Layered materials, layers of graphene, typically in excess of hundreds of layers. Graphite occurs naturally and is the most stable form of carbon under standard conditions. Synthetic and natural graphite are consumed on a large scale (1.3million metric tons per year in 2022) for uses in many critical industries including refractories (50%), lithium-ion batteries (18%), foundries (10%), and lubricants (5%), among others (17%). Graphite converts to diamond under extremely high pressure and temperature. Graphite's low cost, thermal and chemical inertness and characteristic conductivity of heat and electricity finds numerous applications in high energy and high temperature processes. Types and varieties Graphite can occur naturally or be produced synthetically. Natural graphite is obtained from naturally occurring geologic deposits and synthetic graphite is produced t ...

Tributary
A tributary, or an ''affluent'', is a stream or river that flows into a larger stream (''main stem'' or ''"parent"''), river, or a lake. A tributary does not flow directly into a sea or ocean. Tributaries, and the main stem river into which they flow, drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean, another river, or into an endorheic basin. The Irtysh is a chief tributary of the Ob (river), Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
