The geomorphology and seismic stratigraphy of deep-water clastic systems from slope valleys through channel-levee to basin-floor fans have been observed described in modern ancient subsurface examples around the world. However, distribution sedimentary facies, grain size, small-scale architectural elements remains poorly constrained. Extensive exposures (>2500 km2) four stacked composite sequences mapped heterolithic on sand-rich deposits. data set Units C–F Fort Brown Formation Permian...
ABSTRACT The ∼380‐m‐thick mudstone–siltstone‐dominated Vischkuil Formation represents the initiation phase of a 1.3‐km‐thick prograding basin floor to slope shelf succession that marks significant increase in rate siliciclastic sediment supply early Karoo Basin Permian. In upper three well exposed, widespread (∼3000 km 2 ) 10–70‐m‐thick intervals deformed strata are encased within undeformed sediments. Such chaotic mass movement deposits mappable over areas comparable with seismic‐scale...
Abstract Submarine mass movement deposits exposed in the Vischkuil Formation, Laingsburg Karoo Basin, South Africa, provide a rare opportunity to analyse and interpret their emplacement history deformation processes at scale comparable seismic examples. An up 80 m thick slide deposit, continuously two 2 km long sub‐parallel sections, passes from extensionally deformed material (clastic dykes down‐dip facing low‐angle shear surfaces) into compressional toe zone with large (tens of metres...
