Thermal modeling of the UHP Maksyutov Complex in the south Urals

Earth and Planetary Science Letters, 2004
Two-dimensional thermal modeling of the subduction and exhumation of the ultrahigh-pressure (UHP) Maksyutov Complex in the south Ural Mountains tests factors influencing the low modern heat flow in the Urals and the feeble preservation of UHP index minerals.

Plate tectonic model of the South Urals development

Tectonophysics, 1984
Abstract The Uralian Fold Belt originated due to the East European-Kazakhstan continental collision in the Late Paleozoic-Early Triassic. The Uralian paleo-ocean existed from the Ordovician to Early Carboniferous. It evolved along the Western Pacific pattern with island arcs and subduction zones moving oceanwards from the East European margin and ...

The ophiolites of the eastern slope of the South Urals

Tectonophysics, 1986
Abstract Silurian and Middle Devonian ophiolites of the South Urals are characterized. Data on the structure, composition, character of contact and age of the members of the ophiolitic section are listed. The similarity between the magmatic rocks of the South Urals and modern oceanic structures is shown on the basis of petrogenic data and composition

River Flow Formation in the Russian South Urals [PDF]

, 2009
Features of small rivers’ flow formation in the Orenburg region of Russia are analyzed. The flood flow dynamics of the small rivers of the South Urals are presented, in relation to changes in the system of agricultural land tenure in the period 1936–1995.

Microbiota of the Kinderlinskaya cave (South Urals, Russia)

Microbiology, 2012
The mesophilic and psychrotolerant microbiota of the air, soil, water, and bottom sediments of the Kinderlinskaya cave (South Urals, Russia) and the factors affecting the structure of microbial communities were investigated. The pattern of microbial distribution in soils was shown to depend on both the configuration of the cave and the level of ...

Viséan ammonoids from South Urals

International Geology Review, 1966
Two occurrences of Visean ammonoids in the Ural Mountains form the basis for this paper. In the Kzyl-Shin Gorge on the Kiya river, Aktiubinsk province, a bed of gray fragmental limestone, 1 m thick, has yielded the following genera: *Prolecanites, *Pronorites, Beyrichoceras, *Nomismoceras, *Girtyoceras, Trizonoceras, Arcanoceras, and *Goniatites. Also,

Mineralogy of metamorphosed manganese deposits of the South Urals

Geology of Ore Deposits, 2010
A mineralogical investigation of metamorphosed manganese rocks was carried out at ore deposits related to the Devonian volcanic complexes of the Magnitogorsk paleovolcanic belt of the South Urals. The mineralogical appearance of these rocks is determined by three consecutively formed groups of mineral assemblages: (1) assemblages occupying the main ...
