Faults of the Baikal rift zone
Tectonophysics, 1978Abstract Baikal rift-zone faults range in magnitude from major through regional to local. The major, transcrustal faults of pre-Cenozoic initiation frame the structural pattern of the rift zone. Rifting causes a rejuvenation of all important faults regardless of their original type, many becoming oblique-slip faults.

Rifts of the Baikal mountain region
Tectonophysics, 1969Abstract Large and small graben comprising the Baikal rift zone are connected with an extensive Pliocene-Pleistocene uplift with amplitude 3,000–4,000 m above sea level. These grabens inherit the strike of the Early Neogene subsidences and they cannot be considered as the result of fracturing or sinking of the crust in the arch of the uplift.

Tectonophysics, 1978
Abstract No regional geothermal anomaly exists in the Baikal rift. The local heat-flow pattern depends on the degree of neotectonic activity. Mantle heat flow plays the dominant role in determining local geothermal anomalies. The presence of a well-defined relationship between heat flow, geology and geophysical parameters enables prediction of heat ...

Cenozoic lithogenesis in the Baikal rift zone
Lithology and Mineral Resources, 2016New data on the geological history and Cenozoic lithogenesis in depressions of the Baikal rift zone are considered with areas adjacent to Lake Baikal as example. In this region, rifting developed during the plain (Late Oligocene‒Early Pliocene) and orogenic (Late Pliocene‒Holocene) stages and was accompanied by the accumulation of plain coaliferous fan

Asthenospheric diapir beneath the Baikal rift: Petrological constraints
Tectonophysics, 1992Abstract Presence of partially molten material at the base of the crust is one of the key elements in models advanced for the deep structure of the Baikal rift zone. This upper mantle anomaly can be interpreted either as a discontinuous 0–50 km thick layer, which is connected with the asthenosphere via narrow conduits (asthenolith, tensional failure ...

Control on off-rift magmatism: A case study of the Baikal Rift Zone
Earth and Planetary Science Letters, 2018Abstract The Baikal Rift Zone (BRZ) is an active intracontinental rift zone with almost no rift-related magmatism along the rift axis. Most magmatism is observed outside the rift center, and e.g. the major Vitim volcanic field is displaced more than 200 km from the rift center. The reasons for this regional distribution of the magmatism are enigmatic,

The structure and development of the Baikal rift depression
Earth-Science Reviews, 1993Abstract The Baikal rift depression, located in southeastern Siberia, is one of the best investigated intra-continental rift structures in the world. In addition to being the site of comprehensive studies by Russian geo-scientists for decades, the Baikal depression is now the subject of new international investigations using advanced technical means ...

The “seismic quiescence” effect in the Baikal Rift Zone
Journal of Volcanology and Seismology, 2008This paper presents the results from long-term observations of parameters of the Earth’s natural impulsive electromagnetic field (ENIEMF) in the VLF range recorded in the Baikal Rift Zone. We consider the “seismic quiescence” effect and examine possible factors responsible for changes in the daily variations of the magnetic component before earthquakes.

Problems of the seismicity of the Baikal rift zone
Journal of Geodynamics, 1990Abstract The results of investigations of the seismicity of the Baikal rift zone are considered on the basis of an instrumental survey of small shocks, macroseismic information on strong earthquakes of the past, and data on paleoseismic dislocations obtained from seismo-geological observations.
