Fold deformations in the Late Pleistocene deposits of the Khibiny (the central part of the Kola Peninsula): Morphology and genesis

Fold deformations of the Late Pleistocene glaciolacustrine deposits in the south-eastern part of the Khibiny Mountain Massif have been described for the first time. Their formation is connected with the seismogravitational sliding taking place due to seismotectonic movements along the normal fault on the northern slope of the Koashva Mountain. The cyclic occurrence of the deformation horizons in faults testifies to several, presumably close, seismic events that took place in the end of the Late Pleistocene. The obtained data correspond with the information on the palaeoseismic deformations in crystalline rocks and reflect the high seismic potential of the studied area during deglaciation the Late Valdaian (Weichselian).
