Abstract

Aeolian deposits and geomorphological features due to wind erosion have been recorded in the Aremogna plain, near Roccaraso (Central Apennines). At this site, three different aeolian deposits can be distinguished: 1 - silty loess deposits, composed mainly of quartz; 2 - aeolian sand deriving from the reworking of tephra which lies on a peat level dated to 12,850 ± 200 BP; and 3 - aeolian silt coming from the deflation of the deposits 2, which is associated to deflation geomorphological features in part still active. The onset of these processes is more recent than 4690 ± 200 BP. The first and the second aeolian deposits are related to cold and dry phases of the Late Glacial period. The third set of aeolian deposits and deflation features corresponds to wind erosion on a denudated landscape as a consequence of a dry climatic phase the effect of which was amplified by winter freezing-thawing activity. © 1991.
