The methodology of tectonic analysis of complex geological structures is still not exhaustively developed. Deciphering the geological structure and analyzing its development in time often cause difficulties for geologists not only in the course of geological survey, but also in the process of final interpretation of the totality of the actual material in the desk period. In practice there were and still are cases when the structure of the area, for which a conditional geological map was made, was interpreted inaccurately or even erroneously only because of the researcher's insufficiently clear idea of the tasks and content of tectonic analysis.
