Abstract

The upper Pleistocene loess-paleosol sequence of Val Sorda (northeastern Italy) is investigated with paleopedological, micromorphological, and mineralogical methods. Special emphasis is placed on magnetic parameters and analysis of clay minerals. The base of the sequence is an Eemian paleosol, which consists of a rubefied Bt-horizon formed in till. This Bt-horizon is covered by loess, three interstadial paleosols and colluvial deposits. The three interstadial paleosols have a Chernozem morphology and characteristics, reflecting a dry and continental paleoclimate. The top of the sequence is covered by till deposited during the Solferino Stage glacial advance.
