Development of passive margin, due to thermal cooling of the stretch lithosphere, creates a large accommodation space subsequently filled with sediments brought from the emerging continent once the river system is established [1]. This combination of rapid subsidence and sedimentation generates an instable architecture with large shelf progradation on top of early post-rift sediments [5]. Given the typical fine grain lithology of these deposits, in most of the cases they become overpressure and an ideally zone for...

In the northwestern Black Sea the Danube deep sea fan has an extent of over 150 km and stretches from several hundred meters water depth down to the abyssal plain at 2200 m water depth. This large turbiditic system comprises a series of channel-levee systems, with deposits of mass transport. Its evolution was due to the fluctuations of sea level and sediment inputs. Sedimentary and seismic facies identified on the Danube deep sea fan are similar to those that characterize most fans of this type. In the study area ...
