The impact neotectonic movements on exomorphogenesis at the Russian Plain

Abstract

The correlation between amplitudes of neotectonic movements and exogenous processes was calculated. For the whole territory of the plain the impact (R2) of neotectonics reaches 35% for the depth of erosion dissection, 10% - for the density of dissection and landslides intensity, 3% - for karst intensity. External factors cause strong spatial differentiation of the correlation: there are regions with zero correlation and regions where the impact of neotectonic movements is determinant (R² > 80%) for each exogenous process. The impact of neotectonics depends on the age of morphosculpture: it grows significantly in that part of plain, which were not glaciated, and is almost negligible in the Valday glaciation region. The maps of correlation were compiled by the use of moving-circle technique.
