Abstract
The paper presents some multidisciplinary research results on the structure of slip surfaces in segments of tectonic faults in the Baikal region and Mongolia. The properties of subsurface (modern) and deep slickensides exposed after many-kilometer denudation of the Earth’s upper crust are studied at different levels—from macroscale to nanocrystals. Other types of heterogeneities characterizing the structure of fault slip zones are also considered. The presented data indicate a heterogeneous structure of tectonic faults. Their slip zones show both low-friction regions where strong mineral phases are replaced by weak minerals and potentially unstable spots with high friction resistance. Results of the comprehensive study of geological conditions under which different-scale heterogeneities emerge in exhumed fault segments should be taken into account when developing rock mass models suitable for numerical simulation of earthquake preparation processes at the micro-, meso- and macroscales.
期刊介绍：
The journal provides an international medium for the publication of theoretical and experimental studies and reviews related in the physical mesomechanics and also solid-state physics, mechanics, materials science, geodynamics, non-destructive testing and in a large number of other fields where the physical mesomechanics may be used extensively. Papers dealing with the processing, characterization, structure and physical properties and computational aspects of the mesomechanics of heterogeneous media, fracture mesomechanics, physical mesomechanics of materials, mesomechanics applications for geodynamics and tectonics, mesomechanics of smart materials and materials for electronics, non-destructive testing are viewed as suitable for publication.
