NEW DATA FROM NORTHERN APENNINES (ITALY) POLLEN SEQUENCES SPANNING THE LAST 30,000 YRS

Abstract

Bertoldi R., Chelli A., Roma R. & Tellini C., New data from Northern Apennines (Italy) pollen sequences spanning the last
30,000 yrs. (IT ISSN 0394-3356, 2007).
Palynological analyses and radiocarbon dates were performed on lacustrine sequences from the two sites of Berceto (820 m a.s.l.)
and Lagdei (1,254 m a.s.l.) in Parma Province (Northern Italy). This work allowed us to obtain new data and constrains about vegetational and climatic history of the Northern Apennines from Upper Pleistocene to Lower Holocene.
The Berceto core provided a long pollen sequence from the Pleniglacial to the Lateglacial. In it the oscillations of the percentage of
Picea and of the concentration values of AP, allow us to highlight a succession of stadials and interstadials. The correlation among
three climatic amelioration periods found in the Berceto pollen sequence and the interstadials Tursac, Laugerie and Lauscaux was
discussed.
The Lagdei lacustrine sequence, already studied by one of us in the 1980, was newly cored and analyzed in its portion tributable to
the Lateglacial and Postglacial. The results from pollen analyses and radiocarbon dates allowed us to establish that Bertoldi interpretation, questioned by Lowe, was correct and to reconstruct the vegetation characters at the Lateglacial/Postglacial boundary for the Northern Apennines.
