  • Vengono qui presentati alcuni risultati sulla stratigrafia sismica e la morfo-batimetria del bacino sedimentario pleistocenico della Valle di Salerno, che si inquadrano nella stratigrafia sismica regionale del margine continentale passivo della Campania meridionale (Mar Tirreno meridionale, Italia). I dati originali includono un rilievo batimetrico multifascio Multibeam della Valle di Salerno e profili sismici multicanale e monocanale, recentemente acquisiti a bordo della nave oceanografica Urania del Consiglio Nazionale delle Ricerche (crociera oceanografica SISTERII). La Valle di Salerno rappresenta un bacino sedimentario di semi-graben, la cui formazione รจ stata controllata, durante il Pleistocene inferiore. dalla faglia diretta regionale Capri-Penisola Sorrentina, che mostra rigetti verticali di circa 1500 metri e ribassa il basamento acustico carbonatico meso-cenozoico al di sotto del bacino sedimentario.

Abstract
  • New results on the seismic stratigraphy and morpho-bathymetry of the Pleistocene sedimentary basin of the Salerno Valley focused on the regional seismic stratigraphy of the Southern Campania passive continental margin (Southern Tyrrhenian sea) are presented here. Original data include Multibeam bathymetry as well as multichannel and single-channel seismic profiles, recently collected onboard the R/V Urania of the National Research Council of Italy (oceanographic cruise SISTERII). The Salerno Valley represents a half-graben sedimentary basin, whose identification has been controlled, during the Early Pleistocene, by the master fault Capri-Sorrento Peninsula, showing verticl throws of 1500 meters, which downthrows the Meso-Cenozoic carbonatic acoustic basement under the sedimentary basin. The geologic interpretation of multichannel seismic profiles has enabled the identification of a main unconformity, located at depths ranging from 3000 to 3500 metres under the sea bottom and correlated to the top of the Meso-Cenozoic carbonatic sequence, extensively cropping out onshore in the Sorrento Peninsula structural high. THis unconformity bounds upwards the carbonatic acoustic basement, strongly deformed by normal faulting, and represents the base of the Pleistocene basin filling, the Salerno Valley. The basin filling, with an overall thickness exceeding 1000 metres, is characterised by parallel and continuous seismic reflectors alternating with chaotic intervals, having acoustically-transparent seismic facies. The strong synsedimentary tectonics lasting up to Pleistocene times in correspondence to NNW-SSE trending listric normal faults triggered gravity mass instability processes, evident as chaotic acoustic intervals intercalated at various stratigraphic levels in the stratigraphic record shown by the multichannel seismic profiles.
