Zusammenfassung
The subaqueous sediment density flows (SDF) in Mizala (Sorbas Basin, SE Spain) were deposited during the late Tortonian in a middle submarine fan system, near the channel-lobe transition zone. Channel and lobe deposits comprise 6 facies types interpreted as debrites, high-density turbidites, low-density turbidites and hemipelagic autochtonous deposits. The results of this study show the flow transformation of the SDF at the channel-mouth as a consequence of hydraulic jumps. A relative sea-level rise might have conditioned the stacking pattern of the channel-lobe system. This study contributes to understand the sedimentary processes that control the grain size and facies distribution of the SDF deposits at the channel-lobe transition zone, which are of interest in the petroleum industry as they can be potential reservoirs.
