First Results of the Intraformational Conglomerate Test of the Late Riphean Katav Formation (Southern Urals)

Учёные записки Казанского университета: Серия Естественные науки
Detailed petrographic, electron-microscopic, and paleomagnetic studies were conducted on flatbedded synsedimentary carbonate breccias from three blocks of rocks (one block from Minyar, two blocks from Katav-Ivanovsk) to verify the ideas about the time of

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.

Chemostratigraphy of Neoproterozoic carbonates: implications for 'blind dating' [PDF]

, 2001
The delta C-13(carb) and Sr-87/Sr-86 secular variations in Neoproteozoic seawater have been used for the purpose of 'isotope stratigraphy' but there are a number of problems that can preclude its routine use.

Plumes - a new word in Geology of the Urals

Литосфера, 2018
Subject. The ideas of plume tectonics became active and developing only several years later than the theory of plate tectonics. But in the Urals, the question of plume tectonics, contrary to plate tectonics, was not raised, with rare exceptions, until ...
