Aggrading and prograding infill of a peri-Tyrrhenian Basin (Naples Bay, Italy)

High-resolution seismic reflection data are used in the identification of t he stratigraphic succession filling Naples Bay, a tectonically active half- graben located in the extensional margin of the eastern Tyrrhenian Sea. The architecture of the basin infill is characterized by fourth-order depositi onal sequences correlated to Quaternary eustatic oscillations. These deposi tional sequences form aggrading and prograding stacking patterns bounded by tectonically enhanced umconformities. The changes that the stacking patter ns undergo record variations in accommodation space rates. These variations are a result of the tectonic subsidence produced during the evolution of t he half-graben.
