Denudation hollows deepening in the Khibini Mountains during the Holocene

Abstract

The deepening of denudation hollows in the Khibini Mountains (Kola Peninsula) y rockfalls, snow avalanches and rnudflows during the Holocene amounts to 0.5-2.0 meters. Each of the processes of debris transport prevails within certain limits of slope steepness. The radiocarbon age of soil buried in a debris coneindicates the rate of denudation during the early postglacial (0.7 mm per year) exceeded the rate during the Little Ice Age (0.2 mm per year)
