Development of Methods for Integrated Morphometric Relief Analysis for Assessment of Tectonic Fragmentation of the Subsoil

Assessment of the degree of tectonic fragmentation of the upper part of the lithosphere, according to the method of Yu.V. Nechaev [2010] is based on calculations of the specific length of lineaments. On the example of three different regions – the Northwestern Caucasus, the Voronezh anteclise, and the Malko-Petropavlovskaya zone of Kamchatka – we have tested the possibility of using other morphometric parameters: the specific lengths of “weak” zones, elongation lines and streams, as well as the Gaussian curvature of the relief. Their anomalies are confined to seismically active areas and areas of manifestation of hydrothermal-magmatic activity. It is shown that the most informative are 3D models of tectonic fragmentation, built taking into account the specific length of “weak” zones and watercourses.
