Predict: Assessing the Seismic Response in the city of Rome, Part 1. New Data for a Geologic Overview

This work presents the preliminary results of the stratigraphic, paleomagnetic, micropaleontologic and geochronologic investigations carried out on the cores of three boreholes performed in the historic center of Rome within the Predict Project, aimed at evaluating the seismic response within the City through the 3D modeling of the subsoil. Moreover, we have integrated the investigations on the cores of four previously performed boreholes and we use this larger dataset to provide an objective element for the interpretation and validation of a large databank of paper stratigraphies of boreholes carried out for civil engineering purposes in the Roman area. The new data are presented within an exhaustive review of state of the art on the scientific knowledge on the geology of Rome, aimed at providing an updated background for the Quaternary scientists, seismologists, engineers and professional technicians operating in this region. Within this framework, we provide a detailed reconstruction of the chronostratigraphic setting in central Rome, highlighting a coherent picture within the glacio‑eustatic control on the sedimentary processes and providing the background geological input data for the creation of a geo‑database in a dynamic GIS environment, which is the subject of a forthcoming sister‑paper.
