CORRELAZIONE TRA I PRINCIPALI EVENTI TETTONICI, SEDIMENTARI, VULCANICI ED EUSTATICI CHE HANNO INTERESSATO L'ENTROTERRA (CONCHE INTRAPPENNINICHE) E IL MARGINE COSTIERO TIRRENICO LAZIALE DURANTE IL PLIOCENE SUPERIORE ED IL PLEISTOCENE

Abstract

We compare the main sedimentary and volcano-tectonic events that controlled the evolution of the Latian coastal area, from the Middle-Upper Pliocene. The analyses of the strati­graphic sequences correlated via Oxigen isotopie stages dat­ing (for the sedimentary sequences) and radiometric dating (for volcanic sequences), suggest that contemporaneous regional events are due to the same cause. W e than, discuss the hypothesis that Plio-Quaternary glacio-eustatic cycles of sea level, change important elements in controlling extensive tectonism and due volcanic activity, because of changes in the hydrostatic pressure on the magma bodies.
