Relief formation processes in the periglacial zones of Pleistocene and recent forms of erosion relief

Abstract

Gullys and balkas of European Middle Russia have many features of their distribution and structure, which are predefined by relief formation during multifold periglacial epochs of Pleistocene. Solifluction had especially large impact. It developed on the slopes of valleys and balkas, where erodible loams accrued, and resulted in asymmetric profile of erosion forms. Regeneration of normal erosion relief occurred at final stages of periglacial epochs.
