AbstractAbout the AuthorsReferences
In recent years, in the field of tectonic, seismological and seismotectonic investigations, increasing attention is paid to the use of modern GIS technologies. This applies both to the compilation of various tectonic schemes and to the spatial analysis of geodynamic processes. In this regard, for the territory of Armenia, which has a complicated geological and tectonic structure and active geodynamics, the use of modern methods and data is of great scientific and practical importance.

In the article by morphological analysis of modern digital elevation models, using modern GIS technologies, a morphostructural scheme is made that reflects the lineament-block units of the territory of Armenia. Obtained results are confirmed by the comparison with other geological and geophysical data. The Neotectonic (Neogene-Quaternary) activity of the selected blocks was assessed using a number of tectonic-geomorphological indices. Based on the obtained data, the classification of blocks by the level of their tectonic activity is carried out.

Composed map of lineament-block elements and their tectonic activity can be used in various types of tectonic, seismological and seismotectonic studies, as a tectonic basis.
