Based on lithofacies analysis, textural analysis, Thermoluminescence and Infrared-Optical Stimulated Luminescence dating and GIS analysis, three lithofacies units were recognised and their stratigraphic suc- cession identified: 1) the lower unit was deposited during the Pleni-Weichselian within a sand-bed braided river fun- ctioning under permafrost conditions within the central part of the alluvial fan; 2) the middle unit is the result of aeolian deposition and fluvial redeposition on the surface of the fan during long-term permafrost and progressive decrease of humidity of the climate at the turn of the Pleni- to the Late Weichselian; 3) the upper unit accumulated following the development of longitudinal dunes at the turn of the Late Weichselian to the Holocene; the development of dunes was interrupted twice by the form being stabilised by vegetation and soil development.enginfo:eu-repo/semantics/openAccessclimate changeperiglacial environmentfluvial processesaeolian processesluminescence datingArtykułhttps://doi.org/10.1515/logos-2016-0012
