Quaternary structural evolution of Terracina and Gaeta basins (Eastern Tyrrhenian margin, Italy)

In the Terracina and Gaeta basins Quaternary sediments are displaced by normal faults, which affect the Meso-Cenozoic tectonic units of the acoustic basement. The extensional tectonics is characterized by normal faults systems trending NE-SW and E-W. In the Terracina basin, roughly N-S oriented, half-graben structures are downthrown seaward through normal faults; the Gaeta extensional basin, E-W oriented, has two main depocenters and is bounded to the North and to the South by E-W trending normal faults and to the East by a NW-SE trending normal fault.
