Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 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.

Paleogene floral assemblages around epicontinental seas and straits in Northern Central Eurasia: proxies for climatic and paleogeographic evolution [PDF]

open access: yesGeologica Acta, 2009
Paleogene connection of Tethyan and Paleoarctic water masses and biotas was largely enhanced by a N-S trending epicontinental seaway in northern Central Eurasia, which extended from the Aral Sea to the Amerasian deep basin of the Paleoarctic. This seaway

Сonditions of sedimentation and paleogeographic zoning of the Bazhenov horizon (Tithon-Lower Berrias) in West Siberia

open access: yesGeoresursy, 2017
In the global Upper Jurassic-Neocomian (Oxford-Valanginian) black-shale interval, the Bazhenov Formation occupies only the Tithonian – Lower Berriasian. The main regional reasons for this localization were the tectonic regime, the morphology of the basin’

Methane emissions from western Siberian wetlands: heterogeneity and sensitivity to climate change [PDF]

open access: yes, 2007
The prediction of methane emissions from high-latitude wetlands is important given concerns about their sensitivity to a warming climate. As a basis for the prediction of wetland methane emissions at regional scales, we coupled the variable infiltration ...

Estimation of the probability distribution of the number of undetected accumulations in hydrocarbon fields [PDF]

open access: yesНефтегазовая геология: Теория и практика, 2023
The probabilistic distribution of hydrocarbon fields by the number of accumulations in them is an important characteristic of the resource structure of a petroleum bearing basin and can be used to predict the effectiveness of geological exploration.
