Reflection of climatic changes during interpleniglacial in the geoecosystems of South-Eastern Poland
Abstract About 70% of the last cold stage was taken by transitional phases of continuous fluctuations of climate and permafrost extension. All this is reflected especially well in slope types and the thickness of slope, fluvial and aeolian deposits. Very distinct and relatively fast changes took pla...
