Session 3.2 ___ GNGTS 2023 Fig. 1: Detailed model under the city center With this tool, we can use the Lateral Blending option to extrude the data from each borehole point to the almost midpoint between the closest, laterally adjacent borehole point and randomizes correlations within the mid-zone region. The results show that the carbonate bedrock is very articulated because of tectonics. On its top lies a clay and sandstone unit attributable to the Frosinone Flysch (Upper Miocene), followed by a complex of alloantigen series attributable to a generic Messinian sea-lake environment (Lower Pliocene). These sediments are covered by the lacustrine sequence of the Lirino Lake , formed by an alternation of clayey silt and sand with gravel, with thicknesses ranging from a few meters near the carbonate reliefs up to about 150 m in the NW of the Cassino urban area. It should be noted that this sequence, close to the relief of Mt. Cassino, is characterized by the presence of layers of gravel and sand attributable to the Paleo-Rapido riverbed, today diverted by anthropic activity, which probably constituted an ancient tributary of the Lirino Lake, which occupied the Cassino plain in geological times. Traces of the course of the Paleo-Rapido riverbed can also be observed in the buried morphology of the carbonate Bedrock. The characterization of the subsoil has led to the definition of a conceptual geological model that highlights the persistence of the condition of the river-lake environment, at least until the end of the Late Pleistocene.
