Native Gold of the Chudnoe Gold–Palladium Deposit (Subpolar Urals, Russia)

Russian Geology and Geophysics, 2023
Abstract ––The Chudnoe gold–palladium deposit, located within the Central Ural uplift, is confined to the axial zone of an anticlinal structure complicated by faults. Veinlet mineralization is localized in fractured and brecciated Late Riphean–Vendian rhyolites. Native gold and palladium minerals are concentrated mainly in veinlets of Cr-

Nonspecific organic compounds in peat soils of the Subpolar Urals

Eurasian Soil Science, 2017
Specific 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 ...

Zircon Thermometry of the Yarot Granite Massif (The Subpolar Urals)

2019
Zircon 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.

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, 2022
Studying 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 ...

Petrochemical features of acid volcanism of the Sablegorsk Complex (Subpolar Urals)

Проблемы минералогии, петрографии и металлогении. Научные чтения памяти П. Н. Чирвинского, 2022
The 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

Petrochemical features of granite-gneisses of the Nikolaishor massif (Subpolar Urals)

Proceedings of the Komi Science Centre of the Ural Division of the Russian Academy of Sciences, 2021
The Nikolaishor massif is located within the heavily eroded gneisses of the Nyarta metamor¬phic complex and is an au-tochthonous massif composed of plagiogranites and kalispartic granites. The conducted petrochemical study of the least modified variety of granites of this massif made it possible to identify the petrochemical features of the studied ...

Petrology of granites of the Kozhim massif (Subpolar Urals)

Proceedings of the Komi Science Centre of the Ural Division of the Russian Academy of Sciences
The paper presents the study results on granites of the Kozhim massif (the Subpolar Urals). The joint Kozhim massif earlier included the Kuzpuayu granite body. It lies to the north of the Kozhim massif. For this reason, many previously obtained conclusions were summarizing.
