ACTIVE BAIKAL TECTONICS

Abstract

Structural-geological and seismoacoustlc studies carried out in 1989-94 within the Baikal Rill Zone, for the first time show the internal active tectonic structure of the present Baikal Rill lake basin. A series of smaller structure features are distinguished not only by morphology but also by degree of recent activity. Based on the recent structural-geological, seismological, and geophysical data on the deep structure of the sublithospheric mantle beneath Baikal, a more precise estimation is given to the structural characteristics of the active tectonic stress field and to kinematics of rift faults.
