THE KULTUK VOLCANO: SPATIAL-TEMPORAL CHANGE OF MAGMATIC SOURCES AT THE WESTERN TERMINUS OF THE SOUTH BAIKAL BASIN BETWEEN 18 AND 12 MA

Геодинамика и тектонофизика, 2015
The Kultuk volcano erupted at the axial South Baikal basin of the Baikal rift zone (BRZ). Now it exhibits facies of subvolcanic bodies, land-lava eruptions and subaqueous pillow lavas and hyaloclastites.

Neotectonic inversions in the Baikal Rift System

Russian Geology and Geophysics, 2009
Abstract Cenozoic continental rifting in southern East Siberia and northern Mongolia has been associated with subsidence and broadening of rift basins at the account of their mountain borders. This neotectonic trend is, however, superposed with continuous or periodic tectonic inversions in which the basin floor may uplift while marginal ...

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.

Bituminous substances in soils of Baikal Rift zone

IOP Conference Series: Earth and Environmental Science, 2022
Abstract Parameters of hydrocarbon complex of the soils of lacustrine-alluvial plain and sandy uplands of the Baikal rift zone within the Barguzin Depression have been studied. Data were obtained on organic (non-carbonate) carbon, chloroform and hexane bitumoids, as well as on individual polycyclic aromatic hydrocarbons.

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 ...

THREE-DIMENSIONAL VELOCITY STRUCTURE OF THE CRUST IN CENTRAL LAKE BAIKAL FROM LOCAL SEISMIC TOMOGRAPHY

Геодинамика и тектонофизика, 2023
This work deals with the importance of studying seismicity and deep structure of the Earth’s crust in the region of the Baikal rift zone. The study presents a three-dimensional velocity structure of the Earth’s crust in the central part of Lake Baikal ...

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

Variations in molecular and isotopes composition of seepage gases in the north western and south eastern parts of lake Baikal

Georesursy
The paper presents results of gas-geochemical studies of bottom sediments and petroleum potential assessment of Baikal Rift Basin. During the expeditions of the Class@Baikal project in 2014–2019, gases from the Lake Baikal bottom sediments were analyzed.
