EVOLUZIONE TETTONICA DI UN SETTORE PARTICOLARE DEL MARGINE TIRRENICO: L'AREA AL CONFINE TRA LAZIO E CAMPANIA. PRIME CONSIDERAZIONI

Abstract

A large area of the Tyrrhenian margin, including the For­mia plain, Garigliano plain and Riardo plain, has been studied. A detailed geological-structural survey has been car­ried out. This area presents some specific topics which differenziate it from northern and southern zones. After the Apenninic chain building up, the Upper Pliocene-Pleistocene extension dislocates this sector. This disarticolation has been mainly caused by NW trending (Upper Pliocene) and NE trending (Lower-Middle Pleistocene) normal fault system. In this area preexisting E trending discontinuities acted as trans­fer faults. The NE trending fault system conditioned the evo­lution of regional morpho-structures area (Riardo plain and Garigliano Graben) and controlled the Roccamonfina vol­cano evolution.
