Abstract
  • High resolution seismic profiles interpretation and sedimentological and petrophysical correlation of piston cores evidence recent, complex submarine instability processes offshore Cuma, Eastern Tyrrhenian Sea. In the investigated area a network of tributary channels, genetically related to the recent drainage system of Cuma canyon and bounded by slopes showing different profiles, has been identified. Some of them correspond to palaeo-channels, alternating phases of erosion and deposition, which formed, during the last sea level oscillation, a lateral contribution of the drainage system of the Cuma canyon. Seismic interpretation allowed to establish a stratigraphic marker, corresponding to the 18 ky erosional unconformity, clearly individuated at the top of a Late Pleistocene prograding wedge. One of the most significant Holocene units, crops out at the sea bottom and is characterised by limited downward displacement related to creep-type processes. The emplacement of such unit, characterized in the upper part by mud deposits, is interpreted as controlled by high sediment supply, high water contents and shallow gas pockets. (literal)
