The AMUSED project (A MUltidisciplinary Study of past global climatE changes from continental and marine archives in the MeDiterranean region, https://progetti.ingv.it/index.php/it/amused) aims at improving knowledge of middle-late Quaternary climate variability by integrating paleoclimate multi-proxy data acquired in different geological settings of the Mediterranean region. In this context, we investigate the Castiglione maar, Colli Albani volcanic district in central Italy, for acquiring a high-resolution and geochronologically well-constrained multi-proxy record of the lacustrine succession. After geophysical exploration, two parallel 116 m- and 126.5 m-long sediment successions were recovered from the central sector of the basin. The sedimentary infilling mainly consists of fine sand, silt and clay, with minor gravel intervals and numerous tephras mostly deriving from explosive eruptions of the Roman Province volcanoes such as Mt. Vulsini, Vico, Mt. Sabatini and Alban Hills. More than fifty visible volcanic layers were identified and used, together with some lithostratigraphic features, for correlating the two parallel cores and build up a composite sediment section of 131.2 m in length. The geochemical fingerprinting of some key tephra layers allowed to establish a preliminary chronological framework for the Castiglione succession spanning the last 365 ka, with a mean sedimentation rate of 0.33 mm/yr. High resolution X-ray Fluorescence scanning was acquired at 2.5 mm intervals on the composite section and will be used, along with preliminary results from total inorganic and organic carbon, δ18O-δ14C and ostracods analyses, for paleoenvironmental reconstructions.
