Abstract

In the Terracina and Gaeta basins Quaternary sediments are displaced by normal faults, which affect also 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.
