Paleoclimatic record of the past 22,000 years in Venice (Northern Italy): Biostratigraphic evidence and chronology

Palynological analysis indicates two different pollen zones: one is full glacial, with two phases of climatic warming going back to the Tursac and Laugerie interstages; the second corresponds to Holocene lagoonal deposits. The main peat layers represent episodes of stagnation in stadial conditions. The two warm interstages lasted a few centuries. Above the Laugerie interstage, peaty remains in continental sands underlying the Holocene lagoonal deposits of Atlantic age date back to 9173±80-7165±60 years BP, showing the presence of the Early Holocene.
