Controversial Issues of Hydrocarbon Field Formation and the Role of Geomagnetic Fields

International Journal of Geophysics, Volume 2022, Issue 1, 2022., 2022
This review paper presents controversial issues on the formation of hydrocarbon deposits. We look into the geological contradictions of the abiogenic and biogenic theories of petroleum origin, indicating the connection between hydrocarbon deposits and disjunctive dislocations, as well as present disputes about the geological period over which ...

Resting‐state magnetoencephalography source magnitude imaging with deep‐learning neural network for classification of symptomatic combat‐related mild traumatic brain injury

Human Brain Mapping, Volume 42, Issue 7, Page 1987-2004, May 2021., 2021
This study developed a novel resting‐state magnetoencephalography (rs‐MEG) source‐magnitude imaging method, 3D‐MEGNET, using deep learning. The optimized 3D‐MEGNET method combining rs‐MEG data from all frequency bands distinguished individuals with combat‐related mild traumatic brain injury (cmTBI) from combat‐deployed healthy controls with high ...

Resting cerebral oxygen metabolism exhibits archetypal network features

Human Brain Mapping, Volume 42, Issue 7, Page 1952-1968, May 2021., 2021
Calibrated imaging was used during the resting state to recover low‐frequency fluctuations of the cerebral metabolic rate of oxygen. Oxygen metabolism signals demonstrate complex, small‐world topologies and subnetwork profiles consistent with previous anatomical and functional connectivity studies Abstract Standard magnetic resonance imaging approaches

Bazhenov horizon of Siberia (Tithonian – Lower Berriasian): tectonic and hydrodynamic conditions of sedimentation

Georesursy, 2019
The new model of the sedimentation of the Bazhenov Formation, on which black shale accumulated on relative elevation – a shallow-marine hilly plateau, agrees well with the results of a general paleogeographic analysis of the Bazhenov horizon of Siberia ...

Paleomagnetism of Paleocene‐Maastrichtian (60–70 Ma) Lava Flows From Tian Shan (Central Asia): Directional Analysis and Paleointensities

Journal of Geophysical Research: Solid Earth, Volume 125, Issue 9, September 2020., 2020
Abstract The Tuoyun volcanics from the Tian Shan range (Central Asia) give an opportunity to investigate the variability of the Earth's magnetic field during the Cretaceous and Early Paleogene. In the paper we focus on Maastrichtian‐Paleocene basalts and report new paleomagnetic results from 70 lava flows (respectively 45 directional groups) sampled ...

COMPARATIVE PETROPHYSICAL CHARACTERISTIC OF THE CUTS OF THE GERASIMOVSKOE AND KRAPIVINSKOE FIELDS (IN RELATION TO PETROLEUM POTENTIAL OF PRE-JURASSIC DEPOSITS)

Известия Томского политехнического университета: Инжиниринг георесурсов, 2019
The relevance of the research is caused by the need to reproduce the raw material base of hydrocarbons in the southeast of Western Siberia due to prospecting and exploration of deposits associated with pre-Jurassic deposits. The aim of the research is to
