Assessing the Effect of Large Igneous Provinces on Global Oceanic Redox Conditions Using Non‐traditional Metal Isotopes (Molybdenum, Uranium, Thallium)

open access: yesGeophysical Monograph Series, Page 305-323., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Seismotomography of the East European and Barents Pechora platforms: a three-dimensional P-velocity model of the mantle near the Volga-Uralia, the Caspian Basin and the Barents-Pechora Platform

open access: yesГеофизический журнал, 2010
The article is an extension of the set of papers on seismic tomography of the mantle under the East-European platform (EEP). Three-dimensional P-velocity model of the mantle under the EEP and the Barents-Pechora platform (BPP) is considered in the ...

STRAIN RATES FOR THE SOUTHERN SIBERIAN CRATON DERIVED FROM GPS MEASUREMENTS

open access: yesГеодинамика и тектонофизика, 2022
This paper presents quantitative estimates of the strain rates for the southern part of the Siberian craton derived from GPS data. The obtained results confirmed the theoretical concept of low strain rates (10–9×year–1) in the intra-platform areas.

CRUSTS OF WEATHERING AS BASIC SUPPLIERS OF TERRIGENOUS MATERIAL DURING FORMATION OF ANCIENT DIAMONDIFEROUS PLACERS

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2018
On the example of Mesozoic deposits of one of the main diamondiferous regions of the Siberian platform, basic suppliers of terrigenous material into the ancient diamondiferous placers under formation and their occurrences have been characterized. Special
