New insights on morpho-structures and seismic stratigraphy along the Campania continental margin (Southern Italy) based on deep multichannel seismic profiles

Transfer zones in an oblique back-arc basin setting: Insights from the Latium-Campania segmented margin (Tyrrhenian Sea)

“…In the southern Latium region, the structural depression of the Pontina Plain is controlled by a SW dipping normal fault and the oldest basin infill is lower Pliocene in age [ Bellotti et al ., ]. Along the Campania margin, south of the Aurunci Mountains, the main coastal basins are the Garigliano plain, the Campania plain, and the Sele Plain; in this part the extensional phase acted mainly through NE‐SW transverse normal fault systems and took place from late Pliocene to Quaternary times [ Billi et al ., ; Aiello et al ., ].…”

“…TIR10‐13 is the longest seismic profile of the data set; NW‐SE trending, with a total length of about 200 km, it starts offshore Circeo Promontory and reaches the Salerno Gulf. For the aim of this study, the line was processed and interpreted in its northern 80 km: it starts at the edge of the continental margin immediately north of Palmarola basin, crosses the morphological high formed by the Ponza‐Zannone alignment and then the central part of Ventotene basin, until the proximity with the Banco di Fuori and Ischia structural highs [ Aiello et al ., ] (Figures and ).…”

On the occurrence of the Neapolitan Yellow Tuff tephra in the Northern Phlegraean Fields offshore (Eastern Tyrrhenian margin; Italy)

“…Regional geological evidence, coupled with seismo-stratigraphic interpretations, has suggested that the Volturno basin represents a half-graben structure, characterized by blocks downthrown along AIELLO et alii, 2011a;2011b). Rapid flooding of coastal Volturno Plain culminated at 6.5 cal.…”

“…1), a coastal plain of southern Italy located along the Latium-Campania margin. This latter is characterized by Plio-Pleistocene tectonically-downthrown areas genetically related to normal and strike-slip faults linked to the geological evolution of the Eastern Tyrrhenian margin ("peri-tyrrhenian basins"; FABBRI et alii, 1981BARTOLE et alii, 1984MALINVERNO & RYAN, 1986;MARIANI & PRATO, 1988;FLORIO et alii, 1999;BRUNO et alii, 2000;AIELLO et alii, 2000AIELLO et alii, , 2011a2011b;CASCIELLO et alii, 2006) and filled by coastal and marine deposits reaching thicknesses of several thousand of meters. In particular, in the Gaeta basin, extensional tectonics has been active along systems of ESE-WNW, E-W and NE-SW trending normal faults, related to strike-slip tectonic movements that took place mainly during the Late Pliocene-Early Pleistocene time interval (BARTOLE et alii, 1984, AIELLO et alii, 2000, BRUNO et alii, 2000.…”

“…The stratigraphic architecture of the continental shelf during the Late Pleistocene -Holocene time interval is an incomplete 4 th order depositional sequence, that shows an inner strata organization with minor downlap surfaces and erosional truncations separating different phases of progradation (MARANI et alii, 1986;AIELLO et alii, 2000AIELLO et alii, , 2011a2011b;IORIO et alii, 2014b). The last progradation started at about 130 ka and ended at about 18 ka (CATTANEO et alii, 2002;LOFI et alii, 2003;DUVAIL et alii, 2005;LISIECKI & RAYMO, 2005;PELLEGRINI et alii, 2010;CAPRARO et alii, 2011;MASELLI & TRINCARDI, 2013;MASELLI et alii, 2014).…”
