Kinematics of the accommodation structures of the Baikal rift zone

Moscow University Bulletin. Series 4. Geology, 2017
Rift systems are composed of a set of heterogeneous tectonic blocks, which deform under regional extension concertedly, but individually. Such coordination is achieved due to development along the borders of the blocks evolving ensembles of deformation structures, which, in one way or another accommodate discrepancies in the structural style between ...

An anisotropic model of the Earth's crust in the Baikal rift zone [PDF]

Geophysical Journal International, 1984
Summary. An attempt is made to explain the existence of intracrustal low-velocity layers in rift zones by using an anisotropic model. It is supposed that the anisotropy is due to the preferred orientation of micas and amphiboles in metamorphic rocks forming the upper crust.

Differential Craton Destruction Controlled by Fossil Structures in the Central North China Craton

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Craton evolution plays a fundamental role in stabilizing the continental lithosphere and the long‐term evolution of Earth's surface environment. The Shanxi Rift Zone (SRZ) within the North China Craton marks an ongoing craton destruction. Detailed lithospheric structure is essential to explain craton destruction.

Subglacial Topography of Coats Land Records Post‐Gondwanan Landscape Evolution and Early Ice‐Sheet Behavior in East Antarctica

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The East Antarctic Ice Sheet (EAIS) formed circa 34 million years ago and now contains an ice volume equivalent to ∼52 m of global sea‐level rise. Although the EAIS is approximately in balance today, there is substantial uncertainty regarding the sensitivity of sectors underlain by low‐lying bed topography to future climate and ocean warming ...

Crustal Structure Across the Okavango Rift, Botswana: The SEISORZ Wide‐Angle Seismic Experiment

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract The Okavango Rift Zone (ORZ) is an incipient continental rift in Botswana at the terminus of the Southwestern Branch of the East African Rift System. The lack of syn‐rift magmatism and tectonic processes overprinting pre‐rift structures provide an opportunity to investigate incipient‐stage rift processes and the role of pre‐existing structures

CRUST AND MANTLE OF THE BAIKAL RIFT ZONE FROM P- AND S-WAVE RECEIVER FUNCTIONS

Геодинамика и тектонофизика, 2017
We have obtained P-wave and S-wave receiver functions for 10 broadband seismograph stations in the Baikal rift zone (BRZ) and inverted them for seismic velocity models of the crust and upper mantle.

Strain Rates Along the Alpine‐Himalayan Belt From a Comprehensive GNSS Velocity Field

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The Alpine‐Himalayan belt is one of Earth's most dynamic and complex regions, characterized by intense tectonic deformation and seismicity. Comprehensive analyses of continental‐scale crustal deformation and seismic hazards along this extensive orogenic belt require the compilation of large geodetic data sets.

Dip Angles of Mountain‐Front Facets Encode Long‐Term Slip Rates Along the Wasatch Normal Fault, USA

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Mountains bounded by seismogenic normal faults are commonly decorated with facet slopes: planar slopes made of bedrock, or bedrock mantled by regolith, that rise above the fault. The steepness of such slopes is thought to reflect a balance between fault slip and erosion rate.

Lithospheric structure in the Baikal–central Mongolia region from integrated geophysical‐petrological inversion of surface‐wave data and topographic elevation

Geochemistry, Geophysics, Geosystems, 2012
Recent advances in computational petrological modeling provide accurate methods for computing seismic velocities and density within the lithospheric and sub‐lithospheric mantle, given the bulk composition, temperature, and pressure within them.

INTERBLOCK ZONES IN THE CRUST OF THE SOUTHERN REGIONS OF EAST SIBERIA: TECTONOPHYSICAL INTERPRETATION OF GEOLOGICAL AND GEOPHYSICAL DATA

Геодинамика и тектонофизика, 2015
The zone-block structure of the lithosphere is represented by a hierarchically organized pattern of stable blocks and mobile zones which border such blocks and contain highly dislocated geological medium (Fig. 1).
