Abstract

The glacial and slope morphosculpture and correlated deposits of the Late Pleistocene and Holocene in the northeastern part of the Kilgan Mountains (Okhotsk–Kolyma region) were studied. The general three-element structure of loose cover in the glacial valley of Engteri Creek was established: moraine occurs in the lower part; proluvial deposits, in the middle; and covering deluvial deposits, on top. The sequence of postglacial evolution of slope processes was revealed. In the Atlantic (7245–5895 years ago), proluvial flows were the most active: they reached far beyond the slopes and covered moraine. Later, in the Subboreal, surface erosion intensified. The sedimentation rates in Dzhul’etta Lake were calculated. The glacial peak revealed in bottom sediments falls into the period of 19 410–13 880 years ago, with the smallest sedimentation rate, 6.3 cm/1000 years, which is lower compared to the underlying and overlying layers by a factor of two to three.
