Description :
The aim of this study was to recognize the stratification of slope materials in the upper zone (1000–1200 m ASL) of the Sudeten Mts. (SW Poland) and its relation to the morphology and properties of Podzols. Mineralogical and submicromorphological analyzes confirmed autochthonous origin of the parent materials and excluded loess admixture. Macro- and micro-observations proved periglacial formation of deeper beds, while the pollen analysis confirmed the Holocene age of an uppermost sand layer. Finally, four-partial mineral sequences were distinguished in soil profiles : (1) an underlying granite regolith , (2) a basal periglacial layer formed by solifluction, (3) a cryoturbated transitional zone instead of typical intermediate periglacial layer, (4) an uppermost sandy (or a sandy–silty) layer instead of the upper periglacial layer. The same palynological and micromorphological observations confirmed polygenetic nature of Podzols.
