Abstract
Late Cenozoic kinematics and geometry of regional and local active faults in the northern and western sides of the Hovsgol basin have been studied on the basis of satellite imagery and field measurements. W-E faults show reverse-oblique motion with a left-lateral strike slip component; strike-slip components in diagonal faults are right-lateral on NW planes and left-lateral in NE faults. This fault geometry corresponds to transpression with NEN principal compression.
