Deep Structure and Evolution of the Baikal Rift Zone

1978
The varying structural pattern of the Baikal system of rift valleys and faults is defined by interaction of the rift-forming stress field and the structural grain of the basement. The most prominent feature is the central segment of the rift zone which embraces the deepest and largest Baikal depression and is confined to the suture zone between two ...

Deep seismic investigations in the Baikal rift zone

Tectonophysics, 1973
Abstract The largest rift zone of Europe and Asia is located in the region of Lake Baikal. In 1968–1970 deep seismic measurements were carried out along a number of profiles with a total length of about 2000 km within the rift zone and in the adjacent parts of the Siberian platform and the region of the Baikal Mountains.

Control on off-rift magmatism: A case study of the Baikal Rift Zone

Earth and Planetary Science Letters, 2018
Abstract 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,

Organotrophic bacteria of the Baikal Rift Zone hot springs

Microbiology, 2016
Pyrosequencing of the 16S rRNA gene fragments was used to investigate the bacterial community of an Alla hot spring microbial mat. The mat community was mainly represented by the members of five phyla: Deinococcus-Thermus, Nitrospirae, Atribacteria (OP9), Proteobacteria, Chloroflexi, and Firmicutes, with other groups responsible for not more than 2% of

Faults and tectonic stresses of the Baikal rift zone

Tectonophysics, 1992
Abstract The Cenozoic Baikal rift system consists of a central extensional segment which links a southwestern and a northeastern sinistral shear segment. Statistical studies on fault length, amount and sense of slip, depth of crustal penetration and spacing has led to the establishment of empirical relationships which appear to apply also for non ...

A geoelectrical model of the Barguzin basin in the Baikal Rift Zone

Russian Geology and Geophysics, 2007
Abstract We processed data from geophysical survey archives of the 1950s acquired in intermontane basins in the Baikal rift, including a large collection of vertical electric soundings (VES) from the Barguzin basin, which remained only partly interpreted.

Heat flow and gas hydrates of the Baikal Rift Zone

International Journal of Earth Sciences, 2000
Multi-channel seismic studies (MCS), performed during a Russian expedition in 1989 and a joint Russian-American expedition in 1992, have for the first time revealed a “bottom simulating reflector” (BSR) in Lake Baikal. These data have shown that gas hydrates occur in the southern and central basins of Lake Baikal in those places where the water depth ...

Seismicity and earthquake focal mechanisms in the Baikal rift zone

Tectonophysics, 1978
Abstract The seismicity of the Baikal rift zone is considered on the basis of instrumental and field observations. The spatial pattern of epicentres, the frequency of earthquakes and the relations between seismicity and the elements of fault tectonics are analyzed.

Heat flow patterns in Baikal and other rift zones

Tectonophysics, 1969
Abstract A majority of recent data on heat flow observations on the world-wide rift system is from the oceanic ridges. The main feature of these distributions is the presence of a peak in the heat-flow distribution for profiles crossing these structures. The shape of the peak is significant for the interpretation of the origin of the anomaly.

Magnetic anomalies of the Baikal rift zone and adjacent areas

Tectonophysics, 1978
Abstract The magnetic field of the Baikal rift zone differs both from that of adjacent territories and from oceanic rifts in its character and intensity. There is no strip-like structure of the field in Baikal. It is assumed that the thickness of the magnetic anomaly-generating layer in this region is small, due to a high thermal gradient in the ...
