An old regional seismic multicoverage reflection survey (Zone E) provides useful information on the shallow structure of the southern Tuscany-northern Latium shelf located between Elba Island and Anzio. Three main seismic units have been recognized on the grid, directly tied to the Matilde-1 offshore drilling and correlated to onshore wells and outcrops. The upper unit, characterized by continuous and generally undisturbed reflectors, is constituted by the postorogenic sedimentary cover of late Neogene-Quaternary age. This sequence unconformably lies on an intermediate unit or, when absent, a basal one. These two units, characterized by good-to-poor seismic response, are constituted by the tectonized geologic units of the Northern and Central Apennines. The intermediate unit corresponds to the Ligurids and Sicilids allochthonous complexes, while the basal unit may be attributable to the Tuscan nappe and/or the Tuscan autochthon in the shelf sector north of the Tiber River mouth, and the Umbro-Sabina units south of the same mouth. The widespread distribution and consistent thickness of the allochthonous cover (up to 1,000 msec two-way traveltime) lying over a structured substratum might be of some interest in hydrocarbon prospecting.
