CLASTOCARST OF THE SOUTHERN CIS-URALS

Science and innovations 2021: development directions and priorities
It has been established that along with the traditional types of sulfate and carbonate karst, its specific type, clastocarst, is developed in the Southern Cis-Urals. Its general characteristics are given, the regions and the intensity of distribution of clastocarst forms are determined.

Quaternary loess-like deposits of the Southern Urals

Quaternary International, 2006
Quaternary loess-like deposits occur in the Southern Ural region. The loess-like deposits attributed to the Upper Neopleistocene (Kudashevo horizon) are the most widespread and comprehensively studied. Pollen spectra studied in the loess-like Kudashev (late Valdai) deposits suggest dominance of meadow-steppe communities with various herbs, Artemisia ...

Zirconology of serpentinites from Nyashevo massif (Southern Urals)

Doklady Earth Sciences, 2016
Zircons in serpentinites from Nyashevo massif of the Ilmenogorskii complex were dated for the first time by means of the SHRIMP technique. The maximum date of 1892 ± 23 Ma for the zircons accounts for the minimum age of their mantle substrate probably constituting the restite residue.

The Triquetras from the Filippovka Kurgans, Southern Urals

Archaeology, Ethnology and Anthropology of Eurasia (Russian-language), 2020
The triquetra sign is comparatively rare in early nomadic cultures. It occurs mostly in the steppe area east of the southern Urals, specifically on petroglyphs, metal details on horse harness, bronze mirrors, metal plaques, and felted items. This article describes a series of triquetra signs from kurgans 1 and 4 at Filippovka I, representing the ...

Early Devonian suprasubduction ophiolites of the southern Urals

Geotectonics, 2010
The composition of ophiolites widespread in the southern Urals shows that they were formed in a suprasubduction setting. Low-Ti and high-Mg sheeted dikes and volcanic rocks vary from basalt to andesite, and many varieties belong to boninite series. The rocks of this type extend as a 600-km tract.

Sources of anthropogenic radionuclides in the southern Urals

Journal of Environmental Radioactivity, 1992
Abstract About two-thirds of the 137 Cs deposition 10 to 25 km west of Kamensk Uralskyi in the southern Urals comes from unreported releases to the environment. In this area, the contamination from the Kyshtym accident in 1957 was measured at 10 to 60 kBq 90 Sr m −2 , while the deposition of 137 Cs from this accident was less than 1 kBq m −2 ...

POLYMORPHISM OF BIRCHES IN THE SOUTHERN TRANS-URALS

Доклады Российской академии наук. Науки о жизни / Doklady Biological Sciences
Leading monographers of the genus , N. N. Tzvelev and G. V. Kulikov, recognize the independence of birch microscopes. In the Southern Trans-Urals, belongs to this group. Most studies of representatives relied on traditional phenotype-based methods, lacking mechanisms to resolve taxonomic challenges in this complex genus.

The isostatic state of the southern Urals crust

Geologische Rundschau, 1999
The Uralide orogen, in Central Russia, is the focus of intense geoscientific investigations during recent years. The international research is motivated by some unusual lithospheric features compared with other collisional belts including the preservation of (a) a collisional architecture with an orogenic root and a crustal thickness of 55–58 km, and ...
