摘要
New insights on the deep regional geological structure of the Naples Bay are herein proposed through the constraints of seismic interpretation. Regional geoseismic sections along the Ischia8211;Capri8211;Volturno alignment of the Campania continental margin have been constructed. Main regional morpho-structures are: the Banco di Fuori, a morpho-structure high of Meso-Cenozoic carbonates, bounding southwards the Naples Bay; the Dohrn canyon, separating the eastern side of the Bay, where sedimentary seismic sequences crop out, from the western one, where volcanic seismic units prevail; the Capri structural high, a sedimentary high related to regional uplift of Meso-Cenozoic carbonates along the Capri8211;Sorrento alignment; the Magnaghi canyon, eroding the Mg volcanic seismic unit southwards of the Procida island; the Capri basin, a deep basin located south of the Naples Bay, filled by Pleistocene8211;Holocene sediments overlying Meso-Cenozoic carbonatic unit; the Salerno Valley, a half-graben filled by three seismic units corresponding to Quaternary marine deposits, overlying chaotic sequences related to the “Flysch del Cilento” Auct.; the Volturno basin, filled by four marine to deltaic seismic sequences, frequently alternating with volcanoclastic levels, overlying deep seismic units, correlated with Miocene flysch deposits (sands and shales) and Meso-Cenozoic carbonates. On the Naples slope between the Dohrn and Magnaghi canyons a large volcanic edifice, only magnetically known, deeply buried under Quaternary volcanites and genetically related to the Procida volcanic complex has been modelled through seismic interpretation.
