Nature of zircon clastics in the Riphean and Vendian sandstones of the Southern Urals [PDF]

Georesursy, 2019
New age dates of detrital zircons of terrigenous rocks augmented the possibilities of interpretation of their provenance. Unfortunately this interpretation is restricted by a formal comparison of age-and-composition characteristics of detrital crystals ...

THE RIPHEAN MAGMATISM PRECEDING THE OPENING OF URALIAN PALEOOCEAN: GEOCHEMISTRY, ISOTOPES, AGE, AND GEODYNAMIC IMPLICATIONS

Геодинамика и тектонофизика, 2018
The rocks from different stages of the geodynamic evolution have been preserved in the Urals. In its geologic history, the least studied is the transition period between continental rifting and the beginning of oceanic spreading.

The role of proterozoic sediments in the formation of oil and gas content in the northern part of the Volga-Ural oil and gas basin (based on the results of basin modeling)

Georesursy
Two-dimensional basin modeling was carried out along regional profiles (sublatitudinal and submeridional). When modeling, the software package of Lomonosov Moscow State University was used.

Geology and geochemistry of Riphean-Vendian petroleum system (the Northern part of the Volga-Ural Basin)

Georesursy
Riphean-Vendian Petroleum system of VolgaUral Basin (Northern part, Kama-Belsky aulakogen) main elements are described. Reservoirs and properties of them (porosity and permeability), source rocks are characterized geochemically by results of pyrolysis ...

Geodynamic control on the petroleum habitat of the Uralian Foreland

Georesursy
A comparative study of the Uralian Foreland in the Timan-Pechora and Volga Urals basins reveals considerable differences in structure and petroleum habitat. These differences were in large measure controlled by their geodynamic settings.

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.
