Generation of Channelized Mantle Flow Beyond the Rift Zone Accelerated by Thermal Heterogeneity and Rift Propagation

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Rifting is a tectonic process that leads to extensive magmatic activity, continental breakup, and the formation of new oceanic crust. The interplay between rifting and dynamic mantle flow driven by thermal heterogeneity in the mantle along the rift‐axis can influence magmatism and deformation beyond the rift zone.

Prospects of Geoinformatics in Analyzing Spatial Heterogeneities of Microstructural Properties of a Tectonic Fault

Applied Sciences, 2022
The paper proposes a special technique for microstructural analysis (STMA) of rock samples based on two provisions. The first one is an algorithm for the automatic detection and digitalization of microstructures in images of oriented thin sections.

Depositional and stratigraphic evolution of a Permian megalake system: Implications for seiche‐influenced models

The Depositional Record, Volume 12, Issue 2, April 2026.
During the Late Permian, the rise of the Gondwanides Belt trapped marine waters, giving birth to a vast megalake. This lake shifted between overfilled, balanced‐fill and underfilled stages that are recorded by high‐frequency accommodation changes, while meteorological seiches shaped the sedimentary dynamic and produced heterolithic beds.

THE CENOZOIC GRABEN IN THE MARGINAL SUTURE ZONE OF THE SIBERIAN CRATON: INTERIOR STRUCTURAL FEATURES AND TECTONIC STRESS RECONSTRUCTIONS

Геодинамика и тектонофизика
Marginal suture zones of ancient platforms are deep-seated fault zones separating the craton from the mobile belt. Of particular interest is the Pribaikalian marginal suture of the Siberian craton, activated during the Cenozoic rifting.

Fault Friction, Plate Rheology, and Mantle Torques From a Global Dynamic Model of Neotectonics

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Improvements in software, parallel computing, global data sets, and laboratory flow‐laws help to develop the global Earth5 thin‐shell finite‐element model of Bird et al. (2008, https://doi.org/10.1029/2007jb005460) into a benchmark study. All experiments confirm that modeled faults (other than megathrusts) have low effective friction of 0.085 ±

Strong motion record processing of the Baikal rift zone

Spatial Data Processing for Monitoring of Natural and Anthropogenic Processes 2021, 2021
The work is devoted to the adaptation of the earthquake record processing algorithm of the Pacific Earthquake Engineering Research Center to the peculiarities of seismic monitoring of the Baikal region. A tool for forming a database for building a regional seismic attenuation model is presented.

Testing Models for Upper Mantle Earthquakes in the Tanganyika‐Rukwa Rift, Africa

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Rifts that initiate in mechanically strong, stable continental lithosphere are characterized by M > 5 earthquakes at depths >35 km near or below the crust mantle interface. Current models for deep rift zone earthquakes invoke elevated pore pressures associated with magmatism, and rapid stressing from magma intrusions.

NEW APPROACH TO STRONG EARTHQUAKE PREDICTION IN THE SOUTH BAIKAL REGION ON THE BASIS OF ROCK DEFORMATION MONITORING DATA: METHODOLOGY AND RESULTS

Геодинамика и тектонофизика, 2022
The Southern Baikal is located within the actively developing Baikal rift zone (BRZ) that is characterized by a significant seismic potential, and M>7 earthquakes occur periodically with intensive shaking in the epicenters (up to 10 units).
