FEDERICA POLPETTA is an academic who published a paper in 2023 entitled The subsoil of the Colosseum and the detection of the ancient Tiber river Paleovalley (MIS 12-11) in. FEDERICA POLPETTA published this work as part of a team: Mancini, Marco. Here is a description of this work: Core data from five boreholes drilled in 2017 in the Colosseum hypogea are of great interest for defining the Middle Pleistocene fluvial paleogeography and paleoenvironment in the Roman Basin. A detailed facies analysis and lithostratigraphic correlation with numerous other core and outcrop data from nearby areas, including the Palatine, Roman Forum, and Capitoline Hill, were performed in order to precisely reconstruct the subsoil of the monument and of the wider archaeological area. Two well-defined paleovalley infills have been identified, whose formation was linked to sea-level changes correlated to MIS 12-11 and MIS 5d-1 and associated with the ancient Tiber River and the recent Fosso Labicano stream, respectively. The Middle Pleistocene paleovalley stretches in the N-S direction, reaching a width of up to 500 m. I.
