A New Dinosaur Fossil from the Southern Urals

Doklady Earth Sciences, 2021
A caudal vertebra of a dinosaur (Iguanodontia indet.) is described from Upper Cretaceous (lower Campanian) coastal marine deposits of Izhberda Quarry near Orsk (Orenburg oblast). The vertebra is characterized by a rectangular centrum in the lateral view and transverse processes located at the level of the neurocentral suture.

Water erosion in the Southern Ural steppes

Water Resources, 2010
Ecological-hydrological analysis of erosion processes on the key watersheds of Southern Ural steppe was used to determine the surface runoff as a function of the physico-geographic and anthropogenic conditions, i.e., snow storage and soil moisture reserves before winter, whose contribution reaches 68–81%. The rate of humus losses in chernozems and dark

Vendian Suprasubduction Magmatism in the Southern Urals

Doklady Earth Sciences, 2018
New data on the Vendian age of the volcanogenic–sedimentary sequence of the Uraltau zone (Southern Urals) were obtained. The U/Pb (SHRIMP-II) isotope age obtained for zircons from rhyolite tuffs is 591.5 ± 3.5 Ma. The sequence under consideration is intruded by Vendian granites and overlain unconformably by Ordovician terrigenous and volcanogenic ...

The Bereznjakovskoje gold trend, southern Urals, Russia [PDF]

Mineralium Deposita, 1999
The East Uralian Zone south of Cheljabinsk consists of a Silurian to Early Carboniferous volcanosedimentary sequence on Proterozoic basement, intruded by postorogenic Permian granitic rocks. The 7 by 1–2 km Bereznjakovskoje gold trend is hosted by dacitic to andesitic volcanic-subvolcanic units of Late Devonian age. Epithermal gold mineralization is of

Tectonic processes in the Southern and Middle Urals: an overview [PDF]

Geological Society, London, Memoirs, 2006
Abstract The tectonic evolution of the Uralide orogen began during the Late Palaeozoic as the continental margin of Baltica entered an east-dipping (today's coordinates) subduction zone beneath the Magnitogorsk and Tagil island arcs. The subsequent arc-continent collision resulted in the development and emplacement of an accretionary complex ...

Biostratigraphy of the early Middle Pleistocene of the Southern Fore-Urals

Quaternary International, 2016
© 2015 Elsevier Ltd and INQUAA summary of published and unpublished data on the stratigraphy of the early Middle Pleistocene of the Southern Urals region is presented in this paper. It follows previous reviews about the characteristics of the Pleistocene deposits of the easternmost part of Europe.

The fauna of barklice (psocoptera) of the Southern Urals

Entomological Review, 2015
Based on the material collected in 2014 in the Southern Ural State Nature Reserve and adjoining territory, 25 psocopteran species belonging to 17 genera of 8 families are recorded for the first time for the Republic of Bashkortostan. Among these, 20 species, 12 genera, and 4 families are new to the fauna of the Southern Urals, and two species are new ...

Geochemistry of Thorium and Uranium in Soils of the Southern Urals

Eurasian Soil Science, 2017
Specific features of the horizontal and vertical distribution of uranium and thorium in soils and parent materials of the Southern Urals within the Bashkortostan Republic have been studied with the use of mass spectrometry with inductively coupled plasma. The dependence of distribution patterns of these elements on the local environmental conditions is

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.

Measurements of radioactivity in environmental samples from the Southern Urals [PDF]

Radiation and Environmental Biophysics, 1998
A region between Chelyabinsk and Ekaterinburg in the Southern Urals has been heavily contaminated due to operational and accidental releases from the first Soviet plutonium production facility Mayak. In 1992 and 1993, the German Federal Office for Radiation Protection organized a measuring campaign involving two Russian institutes to assist with the ...
