Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 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.

Multiscale Reconstructions, Effective Elastic Properties, and Ultrasonic Responses of Kerogen Matter Based on Digital Organic Shales

open access: yesIEEE Access, 2021
Organic shales usually present significant heterogeneities in rock textures and reservoir properties due to differing kerogen contents and morphologies, subsequently impacting shale elastic properties and acoustic responses.

Three-dimensional molecular modeling of Dachengzi oil shale kerogen [PDF]

open access: yesOil Shale, 2022
A three-dimensional (3D) molecular model of Dachengzi oil shale kerogen was constructed using quantitative 13C direct polarization/magic angle spinning solid-state nuclear magnetic resonance (DP/MAS SSNMR) data and accurate quantum chemistry methods. The

Large undiscovered oil resources are predicted south of Russia

open access: yesJournal of Petroleum Exploration and Production Technology, 2019
Stavropol Region is one of the oldest petroleum provinces on South of Russian Federation. Today, most of its fields are depleted and prospects for the discovery of new large hydrocarbon deposits considered exhausted. However, our studies allow us to talk

Insights into secondary reactions occurring during atmospheric ablation of micrometeoroids [PDF]

open access: yes, 2016
Ablation of micrometeoroids during atmospheric entry yields volatile gases such as water, carbon dioxide, and sulfur dioxide, capable of altering atmospheric chemistry and hence the climate and habitability of the planetary surface.

Application of X-ray Diffraction (XRD) and Rock–Eval Analysis for the Evaluation of Middle Eastern Petroleum Source Rock

open access: yesEnergies, 2021
In this study, collected samples of nine different wells from the Middle East are used for various geochemical analyses to determine the hydrocarbon generation potential. The determination is carried out following the grain density, specific surface area,
