Gold from alluvium of the Puyva region (the Subpolar Urals)
Vestnik of geosciences, 2022In the Puyva region, located in the southeastern part of the Subpolar Urals, several gold-bearing placers and placer occurrences are known; however, information on gold itself is not complete enough, which makes the research relevant. The study of stream gold from the alluvium of the Khartes, Sertynya, Oika, Dorozhny, and Borovoy areas, has revealed ...

The ordovician-silurian boundary on the western slope of the Subpolar Urals
Stratigraphy and Geological Correlation, 2011Data obtained using different methods: paleontological, sedimentological, event stratigraphy and C-isotope chemostratigraphy of a unique succession of the Upper Ordovician and lower Silurian, located on the western slope of the Subpolar Urals, are presented in this work. The data obtained made it possible to revise some existing ideas about the texture

Discovery of a Diplochone (Rugosa) in the Silurian of the Subpolar Urals
International Geology Review, 1965Diplochone kozhimica n. sp. is described from deposits of Ludlow age in the northern Urals. One of the described specimens grew on the surface of a colony of Squameofavosites sp. The morphologic effects on the rugose coral include basal processes that extend into the tabulate corallites, a broad, enlarged base, and stereoplasmic thickening of skeletal ...

Palaeoglaciations in the Polar and Subpolar Ural Mountains.
The Ural Mountains form a major physiographic boundary between the East European Plain and West Siberia, both repeatedly glaciated during the Pleistocene by the Barents–Kara ice sheet. Although the present-day topography reflects significant glacial modification, the extent, chronology, and interaction of mountain glaciers with the Barents–Kara ice ...Bartosz Kurjanski +6 more

BISMUTH IN BORNITE FROM THE LOWER ORDOVICAN GRAVELITES (SUBPOLAR URALS)
Выпуск 26, 2023For the first time, the presence of bismuth, rare for the north of the Urals, was found in the gravelstone of the Lower Ordovician Obeiz Formation in the Subpolar Urals. Bismuth is represented by small rounded grains (about 1 μm) that form chains in bornite.

Nonspecific organic compounds in peat soils of the Subpolar Urals
Eurasian Soil Science, 2017Specific features of organic matter, molecular composition and distribution of oxygen-containing nonspecific organic compounds (fatty acids, long-chain aliphatic alcohols, and ketones) were revealed in two peat soils on slopes of the Subpolar Urals: the eutrophic peat soil of the spring mire (Hemic Histosols) and the peat soil of a slope mire (Fibric ...

Zirconium-hafnium geothermometer for А-granites of the Subpolar Urals
Proceedings of the Komi Science Centre of the Ural Division of the Russian Academy of Sciences, 2022Studying the relationship of fluctuations of zirconium and hafnium in magmatic zircon and mineral-containing rock allowed L.Y. Aranovich and N.S. Bortnikov to develop a ge¬othermometer based on this marker ratio. The study of silicate and microprobe analyses from granites of A-types in the north of the Subpolar Urals made it possible to de¬termine the ...

The age of relief in northern, subpolar and polar Urals
International Geology Review, 1967Reexamination of geological data available for the Northern, Subpolar and Polar Urals indicate that the relief of the area, originally considered to be ancient, is much younger in age. The absence of weathered crusts, Neogene deposits and other indirect evidence suggest a regional uplift of the area during the Neogene. -- IGR Staff.

Zircon Thermometry of the Yarot Granite Massif (The Subpolar Urals)
2019Zircon is one of common accessory minerals of igneous rocks. Geochemical and morphological features of this mineral reflect physicochemical properties of the mineral formation medium. It provides additional information about the nature and formation conditions of the rock.

Petrochemical features of acid volcanism of the Sablegorsk Complex (Subpolar Urals)
Проблемы минералогии, петрографии и металлогении. Научные чтения памяти П. Н. Чирвинского, 2022The study of the composition of the rock using petrochemical, geochemical and other analytical studies makes it possible to obtain quantitative information about the content of chemical elements, more accurately diagnose the object under study and create an idea of its genesis. Acidic volcanics of the sablegorsk subvolcanic complex (Subpolar Urals) are
