Rich pteridosperm collection from the Visean (Mississippian, Lower Carboniferous) of the South Urals, Russia, was studied. A brief review of previous plant findings from the Lower Carboniferous of the region is considered. Two genera and six species including a new species Adiantites tevelevii sp. nov. are described. A new species is determined on ...

This paper reports first isotope–geochemical data on the Early Devonian magmatic rocks of the Chanchar potassic mafic volcanoplutonic complex of the Sakmara zone of the South Urals. The incompatible element distribution and ratios indicate that the rocks of the volcanic, subvolcanic, and intrusive facies are comagmatic and were derived from a commo...

PurposeThe aim was to study Cu (II), Zn (II), and Pb (II) forms in technogenically transformed soils adjacent to the Karabashmed copper smelter.Materials and methodsStudies were performed in the plume zone of the Karabash smelter and in the floodplains of Ryzhii Brook and Sak-Egla River. Geomorphological and geochemical migration processes prevail ...

Paleomagnetic data may contribute to studying the formation history of orogens; in particular, these data can promote identifying the pattern and scales of deformations at the final stages of orogeny. We have conducted paleomagnetic studies of the Paleozoic and Neoproterozoic sediments in the western part of the Western Ural Megazone in South Urals...

The Slyudyangorsk muscovite deposit in the southern Urals was explored and mined in 1926–1957. By the mid-1950s, 104 veins of quartz–feldspar pegmatites including 21 muscovite-bearing veins have been found. Pegmatites with giant black Y-bearing epidote crystals are crosscut by veins with giant muscovite crystals, which, in turn, are intersected by ...

New and previously published data on the distribution of 12 bat species in the Cis-Urals and South Urals (Republic of Bashkortostan) are summarized. Data on their subspecies status are given. There is a need to clarify the taxonomic status of the pipistrelle bats Pipistrellus pipistrellus/pygmaeus. In terms of composition, the bat fauna of the Repu...

Analyzed is the cycle of ice cover lifetime for a typical lake in the South Urals corresponding to the 11-year cycle of solar activity. It is revealed that the amplitude of oscillations of the ice cover lifetime gradually decreases as the contribution of the cyclic component lowers and the impact of the irregular component increases. The linear tre...

Mycorrhiza was studied in the roots of Triticum aestivum L. plants in three natural zones of the Republic Bashkortostan. Plants growing in the foothills of the Urals steppe had higher degree of mycorrhization, while plants in the Trans-Ural Region steppe and in the Northern forest-steppe had a lower degree. Mycorrhization of Triticum aestivum L. ro...

The initial phase of MIS 5e is associated with the first half of the Last Interglacial period. Reconstruction shows a change in plant communities of MIS 5e from broad-leaved Mediterranean species in western Europe to broad-leaved peri-Carpathian species of the East European Plain to broad-leaved-steppe communities of South Urals and dark taiga vege...

Two lakes—Bolshoye Miassovo and Turgoyak—are used as an example to discuss long-term variations in the structure of phytoplankton and to assess (using indication) the current trends in water quality changes in deep mountain lakes of the South Urals. It is shown that the seasonal dynamics of phytoplankton biomass and structure is characterized by lo...
