A technique for constructing digital neotectonic maps using the ArcMap, Kingdom, Surfer, and other software systems that is different from the previously used techniques for these constructions is presented. It is based not only on geological and geomorphological information, but what is essential, the modern kinematics of the earth’s surface, that is, vertical velocities, lineament division of the earth’s crust and its erosion component. In this case, the sum of these parameters retains the method of actualism and increases the boundary of the neotectonic stage, comparable with the previously accepted and justified age – the Late Paleogene – the Early Neogene. In addition, it disappears, as a negative factor, the reservation of the role of intrusive and igneous rocks, as well as other deposits, comparable in strength to the processes of weathering and denudation. It has been established that when applying the method of work considered in the article, the appearance of the latest deformations changes significantly, in contrast to previously published maps, which will undoubtedly affect the forecast of certain minerals taking into account the latest tectonics.

Keywords: neotectonics, neotectonic map construction methodology, modern vertical speeds, radar interferometry, erosion component of the relief, geological and geomorphological basis, ArcMap, Kingdom, Surfer programs.
