Abstract
Loess deposits have been described in the past for the upper section of Buca Dei Corvi succession (Central Italy). In this paper the depositswere re-analysed to clarify the depositional environment and to attempt a paleoclimate reconstruction. Two radiocarbon dates on pedogenic carbonate constrain the ages to the Late Glacial, and are consistent with previous OSL dating of the top of the succession. The non-marine mollusc assemblage shows typical character of cold and dry climatic conditions, testified by strong oligotypical composition. Mineralogy and geochemistry of the sediments indicate the abundant presence of exotic quartz mineral which can be explained only by wind transport. Probably,wind transportwas also responsible of deposition of carbonatewhich then dissolved and re-precipitated producing pedogenic concretions. Stable isotopes (13C/12C and 18O/16O ratios) of the concretions are consistent with a climate drier than present conditions, with an environment characterized by sparse vegetation.
