Specific slushflow phenomena, the most widespread type of debris flows in the Subarctic climate, are one of the essential landforming agents for the valleys of the Kola Peninsula mountains. However, some texture analyses of the debris flow debosits and 14C dating of the buried organic-rich lenses in the Khibiny and the Lovozerskiye Tundry show that during the Holocene the magnitude of the debris flows events and the composition of their deposits changed. During the last deglaciation and the Early Holocene according to water and sediment sources and isostatic uplifts of the territory there were the largest debris flow events caused by moraine-dammed lakes breaches. Later the slushflows with much lower clastic content, which explaines smaller accumulations, occured. The study was funded by RFBR project №17-05-00630.
