Are slump folds reliable indicators of downslope flow in recent mass transport deposits?

G.I. Alsop, R. Weinberger
2020 Journal of Structural Geology  
Fold hinges define broad arcs at high angles to flow in the downslope toe of the slump 15 and progressively swing to become sub-parallel to flow in the upslope region.  ...  In some instances, folds have nucleated around longer 20 (>10 cm) wooden sticks that were incorporated into the slump, whereas shorter wooden fragments 21 align parallel to the flow direction.  ...  parallel to the flow direction at 2 m from the toe of the slump on the NW side of the gully 884 (see Fig. 5b).  ...

This parallelism sup- ports but does not prove the contention that fold vergence indicates movement direction of this slump sheet.  ...  In contrast, (b) if the currents moved oblique or transverse to the slope, slump sheet movement would have paralleled paleocurrents only if current over- flow initiated slumping.  ...

Dewatering structures, which are strongly dependent on the development of imbricate structures within slump sediments, acted to drain excess fluid that accumulated upon the slip planes related to slumping  ...  Damped and dimmed refl ections in the dewatering structures and in the slumps indicate that the distribution of natural gas is strongly related to fluid circulation in and around the slump sediments.  ...  Parallel dikes (apparent in the images as linear features) strike perp e n d i c u l a r t o t h e direction of slumping (arrows).

Likewise, the small NE-SW features evident within the lobe that appear to parallel regional trends were either formed after slumping or indicate that the style of slumping was such that some rift-related  ...  As described above, we interpret the presence of smaller structures paralleling these regional trends as evidence that the style of slumping allowed some preservation of these features.  ...
