Geodynamics of the Katunsky fault (Gorny Altai) according to structural and kinematic data

Abstract

In the Katun Fault Zone, the structural-paragenetic analysis of stress indicators and the method of cataclastic analysis of discontinuous faults have been used to determine the features of the structure of this fault and the conditions of its formation at the Late Alpine stage. It is proved that the Katun Fault Zone is the strike-slip fault that develops at different sites in transpressive or transtensive conditions. The newest grabens along the zone were formed under strike-slip fault displacements and locally manifested conditions of horizontal extension or horizontal extension with shear.
