“…Within the same slope valley, differential compaction was responsible for the lateral offset of successive gravity‐driven deposits (Brown, 1975; Pinoteau, 1986) and may be observed at two levels. First, very thick bodies, such as the Σ2 slump, are characterized by a convex‐up upper surface reflecting subdued compaction associated with the accumulation of the largest rafts and blocks in the axial region of the slump; subsequent deposits were deflected around and accumulated on the flanks of the earlier slump bodies (Friès et al ., 1984; Friès & Rubino, 1990).…”

The Aptian succession on the Vocontian palaeomargin (south‐east France) consists of marl and marly calcareous pelagic slope facies together with a range of gravity‐driven deposits (slumps, debris‐flow deposits, turbidite packages and massive sandstones). The massive sandstones were emplaced by high‐density turbidity currents and are associated with extensive clastic sills and dykes. The sedimentology is constrained by a high‐resolution bio‐ and lithostratigraphic framework and permits a detailed analysis of the slope succession including: (1) a sequence stratigraphical analysis of the slope deposits; and (2) lateral tracing of individual sedimentary packages downslope. The resulting model for the Vocontian slope represents an alternative to the ‘classic’ Exxon delta‐fed, mud‐rich model. Key elements of the Vocontian model are: (1) an emphasis on lowstand slope erosion and complex slope morphology controlled by contemporary tectonism and salt diapirism; (2) slope deposition in confined erosional and structurally controlled conduits rather than the buildout of slope fans/channel‐levee complexes; (3) a dominance of large‐volume muddy slump and transitional debris‐flow deposits, with subordinate sandy turbidites, including significant massive sandstone facies; (4) common sand injections (sills and dykes) associated with the massive sandstone facies; and (5) minimal downslope evolution of the flows, with the nature of the source sediment being the over‐riding factor determining flow behaviour and deposit character. The Vocontian system is a rare instance in which large sections of a ‘fossil’ passive margin slope are preserved in the geological record. The slope deposits differ from the classic models of turbidite systems that have mainly been built from peripheral foreland basins, and the new insight makes it possible to compare ancient and present‐day passive margin slope systems.

“…This created natural drainage ways which in turn caused continual sand deposition and overall thickening of the sand body (Brown, 1975). The offset nature of the sandstone body, as seen from the cross section, is interpreted to represent compaction of the adjacent fine grained sediment which again caused the depocenter to shift to the lower topographic surface.…”
