Variations of Th/U values in Vendian clayey rocks of north-east East-European Platform and Middle and Southern Urals as reflection redox status of sedimentary basins

Литосфера, 2017
Earlier, we considered the features of the redox changes in the near-bottom layer of water in the sedimentation basins that existed during the Late Riphean and Vendian in the eastern and northeastern (in modern coordinates) margins of the Baltic.

New data on geochemical features, fluid mode, age and potential ore content of granitoids of Isherim anticlinorium (North Ural)

Литосфера, 2018
Granitoids of Ishirim anticlinorium which is one of the major Precambrian structures of the North Urals, are poorly studied by modern geochemical and isotope-geochronological methods that led to the existence of different points of view on formation ...

Redox bottom-water conditions in Neoproterozoic basins on eastern and north-eastern periphery of East-European Platform

Литосфера, 2015
The redox bottom-water conditions in the sedimentary basins, which existed during the Late Riphean-Vendian on the east and north-east (in modern coordinates) margins of the Baltic, are investigated.

Литогеохимический облик отложений ашинской серии венда западного склона Южного Урала

Литосфера, 2019
Показано, что песчаники ашинской серии сопоставимы с составом среднего протерозойского кратонного песчаника только по средним содержаниям оксида кремния. Концентрации остальных породо­образующих оксидов в них как заметно выше, так и ниже.
