Sakha Republic
Sakha, officially the Republic of Sakha (Yakutia),, is the largest republic of Russia, located in the Russian Far East, along the Arctic Ocean, with a population of roughly 1 million. Sakha comprises half of the area of its governing Far Eastern Federal District, and is the world's largest country subdivision, covering over 3,083,523 square kilometers (1,190,555 sq mi). ''Sakha'' following regular sound changes in the course of development of the Yakut language) as the Evenk and Yukaghir exonyms for the Yakuts. It is pronounced as ''Haka'' by the Dolgans, whose language is either a dialect or a close relative of the Yakut language.Victor P. Krivonogov, "The Dolgans’Ethnic Identity and Language Processes."

Wuliuan
The Wuliuan stage is the fifth stage of the Cambrian, and the first stage of the Miaolingian Series of the Cambrian. It was formally defined by the ICS in 2018. Its base is defined by the first appearance of the trilobite species ''Oryctocephalus indicus''; it ends with the beginning of the Drumian Stage, marked by the first appearance of the trilobite ''Ptychagnostus atavus'' around million years ago. The 'golden spike' that formally defines the base of the period is driven into the Wuliu-Zengjiayan(乌溜-曾家崖)section of the Kaili formation, near Balang Village in the Miaoling Mountains, Guizhou, China. GSSP Three sections were discussed as GSSP candidates: the Wuliu-Zengjiayan section near Balang in Guizhou province (China), a section on Split Mountain in Nevada (USA) and the "Molodo river section" along the Molodo river (Sakha Republic, Russia). The Wuliu-Zengjiayan section is an outcrop of the Kaili Formation in the Wuliu quarry. The first candidate for the beginn ...

GSSP
A Global Boundary Stratotype Section and Point (GSSP) is an internationally agreed upon reference point on a stratigraphic section which defines the lower boundary of a stage on the geologic time scale. The effort to define GSSPs is conducted by the International Commission on Stratigraphy, a part of the International Union of Geological Sciences. Most, but not all, GSSPs are based on paleontological changes. Hence GSSPs are usually described in terms of transitions between different faunal stages, though far more faunal stages have been described than GSSPs. The GSSP definition effort commenced in 1977. As of 2022, 77 of the 101 stages that need a GSSP have a ratified GSSP. Rules A geologic section has to fulfill a set of criteria to be adapted as a GSSP by the ICS. The following list summarizes the criteria: * A GSSP has to define the lower boundary of a geologic stage. * The lower boundary has to be defined using a primary marker (usually first appearance datum of a fo ...

Drainage Basin
A drainage basin is an area of land where 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 a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syungyude
The Syungyude (russian: Сюнгююдэ, sah, Сүҥгүдэ, ''Süŋgüde'') is a river in the Sakha Republic (Yakutia), Russia. It is the largest tributary of the Molodo, of the Lena basin. Its length is and the area of its basin . The Syungyude flows across the Zhigansky and Bulunsky district. The banks of the river are uninhabited. Geography The Syungyude originates in the eastern Central Siberian Plateau. In its upper course it flows southeast for a long distance, finally descending into a floodplain. It meanders strongly just north of the Motorchuna, flowing parallel to it until it turns northeast and then NNE in a wide arc. In its last stretch the Syungyude flows roughly northwards with the floodplain of the Lena to the east. It runs parallel to the great river until it joins the right bank of the Molodo upstream of its mouth in the Lena.Google Earth Tributaries The longest tributary of the Syungyude is the long Kyuskyurdeen (Кюскюрдьээн), joining it f ...
