Main areas of scientific activity ( A – D ):

A. FOLDING formation research

Investigations are based on tectonophysical approach, such as detection of mechanisms, strain value estimation, solutions of typical tectonic problems,
reconstruction of geometry of structures boundaries

            List of main papers in Folding (updated 12-01-2018)
(by F.Yakovlev, with download of pdf-files of all papers, 1978 – 2017 years)

Guide in Folding ( I – VII ):
– about the study of folded structures of several scale levels into thin-layered flysch-like sediments of HINTERLAND.  
Be carefully!
HINTERLAND structures are quite different from the typical FORELAND structures.

            Numerous methods and its applications are showing with explanations and papers links from small to larger objects;
                       
Folders below (1-19) are related to tectonic and tectonophysical problems:

I          THE THEORETICAL REASONS

            1. “Foreland type of folding” vs. “Hinterland multi-scale folding”: comparison of mechanical properties

            2. Hierarchic system of 7 ranks levels of folded objects

            3. Multi-rank strain analysis of linear folded structures

II         SEPARATE FOLDS AND AN ESTIMATION OF STRAIN (shortening) VALUE

            4. Intra-layer structures (rank 1)

            5. Fold morphology classification based on mechanical properties of layering (rank 2)

            6. Single viscous layer folds (rank 2)

III       LOCALE STRUCTURES AND THEIR MECHANISMS ANALYSIS USING THE STRAIN

                        ELLIPSOID OF DOMAINS

            8. Strain ellipsoid of a fold and of a folded domain (ranks 2, 3)

            9. Statistics of folded domain geometry in NW Caucasus and inclined shearing zones (rank 3)

            10. Estimation of values of folds shortening for study of nappe structures origin (ranks 2, 3)

B. Study of mechanisms of MOUNTAINS BUILDING Und Con

                        List of main papers, download papers

                        The approaches to study of two main types of mountain building processes and structures are described.
                        These types are: 1) post-platform mountains and 2) post-folded mountains.

C. Seismotectonics Und Con

                        List of main papers

                        There are materials of three topics. The kind of regularity in seismic periodicity in North Caucasus is described.
           
There are results of geological observations in Racha earthquake (1991, Georgia) and Shikotan earthquake (1994, Kuril island, Russia).

D. Study of mechanisms of fracture formation Und Con

                        List of main papers, download papers

                        There is explanation of new approach in study of fracture formation (It was started in cooperation with the
deceased leader D.Osokina and now it is continuing with V.Voitenko). The complex tectonophysical description of single
fracture formation as joint of stress-field, strain-field, displacements and secondary fracturing is offering.
