چکیده انگلیسی
In the NCA, localized minor deposition of aeolian dust is documented - by other authors - from plateaus deglaciated only during the late-glacial to Holocene; no evidence, however, exists for another phase of similarly widespread aeolian deposition such as that which gave rise to the described regional drape of silt. Intense aeolian transport and deposition was probably a direct consequence of the liberation of huge amounts of unsorted sediment during deglacial ice collapse, perhaps combined with climatic aridification. This provides a hitherto unappreciated element of the deglacial to paraglacial phase: intramontane dust storms. Because of its large extent and the availability to OSL dating, the aeolian drape provides an excellent geochronological marker level identified in terrestrial post-glacial successions of the Eastern Alps. Because of its fine-grained siliciclastic composition, the drape gives rise to widespread development of atypical Cambisols (on carbonate bedrocks) with comparatively high water storage capacity and nutrient supply.
