N1 - Funding Information:
This article is a contribution of project “FUcino Tephrochronology Unites Quaternary REcords (FUTURE)”, supported by the Italian Ministry of Education, University and Research (MIUR, grant PRIN No. 20177TKBXZ_003; G. Zanchetta, coordinator). An international consortium, including IGAG-CNR, IGG-CNR, University of Pisa, INGV-Roma, LIAG-Hannover, University of Cologne, University of Rome La Sapienza, University of Geneva, University of Nottingham, provided the funding for supporting the 2017 Fucino drilling campaign. We thank Antonello Provenzale for the additional financial support offered for the drilling. The 40Ar/39Ar age was supported by the CNRS INSU LEFE action to S. Nomade. The Fucino project is co-funded by DFG (German Research Foundation) grant WA 2109/16. Two anonymous reviewers provided thoughtful and constructive comments that improved the manuscript.

N2 - Here we present the first tephrostratigraphic, palaeomagnetic, and multiproxy data from a new ∼98 m-deep sediment core retrieved from the Fucino Basin, central Italy, spanning the last ∼430 kyr. Palaeoenvironmental proxy data (Ca-XRF, gamma ray and magnetic susceptibility) show a cyclical variability related to interglacial-glacial cycles since the Marine Isotope Stage (MIS) 12-MIS 11 transition. More than 130 tephra layers are visible to the naked eye, 11 of which were analysed (glass-WDS) and successfully correlated to known eruptions and/or other equivalent tephra. In addition to tephra already recognised in the previously investigated cores spanning the last 190 kyr, we identified for the first time tephra from the eruptions of: Tufo Giallo di Sacrofano, Sabatini (288.0 ± 2.0 ka); Villa Senni, Colli Albani (367.5 ± 1.6 ka); Pozzolane Nere and its precursor, Colli Albani (405.0 ± 2.0 ka, and 407.1 ± 4.2 ka, respectively) and Castel Broco, Vulsini (419–490 ka). The latter occurs at the bottom of the core and has been 40Ar/39Ar dated at 424.3 ± 3.2 ka, thus providing a robust chronological constrain for both the eruption itself and the base of the investigated succession. Direct 40Ar/39Ar dating and tephra geochemical fingerprinting provide a preliminary radioisotopic-based chronological framework for the MIS 11-MIS 7 interval, which represent a foundation for the forthcoming multiproxy studies and for investigating the remaining ∼110 tephra layers that are recorded within this interval. Such future developments will contribute towards an improved MIS 11-MIS 7 Mediterranean tephrostratigraphy, which is still poorly explored and exploited.
