Magnetic anomalies of the Baikal rift zone and adjacent areas

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 crust. Basic intrusions are predicted at depths up to 18 km. There is evidence of instability in the geothermal field.
