“…Dismantling processes are closely related to the increase of pore pressure within water-saturated materials (Owen, 1987;Spalluto et al, 2007). The loss of shear resistance is evidenced within the slumps with amplification of folding (Aslop and Shmuel, 2011), disaggregation (Corbett, 1973), or liquification (Farell, 1988), progressively leading to the destruction of bedding.…”

Integrated in the peri-Adriatic domain, the Ionian Basin extended along a NW-SE direction during the Late Cretaceous, limited on its sides by the Apulian and the Kruja platforms. The basinal/slope succession was studied in seven outcrops exposed in the Albanian fold-and-thrust belt. Sedimentological investigations, supported by bio-and chronostratigraphy were performed on calcareous Upper Cretaceous hemipelagites, gravity-flow deposits and slumps. The western part of the basin was studied, revealing a strong influence of the Apulian margin, alternatively shedding sediment basinward, by means of a tectonically controlled edge. The Late Albian to Cenomanian period is characterized by the settling of muddy debrites along the margin. A deep basinal environment characterizes this period which prolongs until the Santonian, with no significant influx of the platform basinward. This sedimentary setting abruptly changed at the end of the Santonian, with an important influx derived from both platforms. Coarsening and thickening upward sequences show a progressive increase in sediment shedding during the Campanian. The Late Campanian-Early Maastrichtian period points out a major change on the resedimentation processes with the settling of several slumped units reworking thick sediment packages. The latter can be traced along the Apulian margin, testifying of instabilities along the edge of Apulia.

“…MTCs, and have been previously described from field outcrops, where they are traditionally used in the determination of palaeoslope direction (Farrell, 1984;Farrell and Eaton, 1988;Webb and Cooper, 1988;Eva and Maltman, 1994;Bradley and Hanson, 1998;Strachan, 2002aStrachan, ,b, 2006. Farrell andEaton (1987, 1988) proposed that MTCs which have undergone relatively little translation will feature upright folds developed by buckling, and progressively more deformed (i.e.…”

“…more translated) MTCs will be characterised by tight to isoclinal, and recumbent folds. Such features develop due to simple shear (Escher and Waterson, 1974), which through time will rotate fold axial surfaces towards parallelism with the upper and lower MTC surfaces, and fold hinges towards the downslope direction (Farrell and Eaton, 1988). Folds in the translated body of a MTC can therefore be useful in identifying the transport and palaeoslope direction, and possibly in determining the degree of translation.…”

“…There is a wide range of soft sediment deformation features, many of which, such as load marks and mini diapirs, can be ascribed to syn-sedimentary or early postdepositional settlement and dewatering. Other ductile features, such as sheared-out folds, are associated with a weak axial planar cleavage, and are tentatively interpreted to be of tectonic origin (but see Farrell and Eaton, 1988). The folds are sometimes overprinted in the same samples by more "brittle" (i.e., more localized) deformation features, such as thin shear zones and arrays of kink folds.…”

Deformed sediments collected from drilling at the Cascadia forearc were examined using optical and electron microscopy. A wide range of microstructures was encountered in a sample suite consisting mainly of fine-grained sediments. Most of the samples were recovered from the Oregon sector of the accretionary wedge, at Site 891, located at the deformation front, and Site 892, located on the second thrust ridge. For purposes of comparison, we also examined a small number of samples from the undeformed Cascadia Basin (Site 888) and from behind the second thrust ridge at the Vancouver Margin (Sites 889 and 890).Within each site, there is a strong compositional control on the style of deformation. Diatomaceous silts tend to show a more brittle style of deformation than either clay-rich silts or sands. Arrays of subparallel shear zones and incipiently scaly textures are developed in clay-rich sediments.At Site 891, intense deformation is largely confined to the vicinity of fault zones, where thick (tens of meters) intervals of incipiently scaly fabric and thin (tens of centimeters) zones of fault gouge are developed. Chaotic, small-scale folding is present at several horizons, and, in some cases, is overprinted by shear zones.Deformation at Site 892 is much more pervasive, with widespread fracturing producing a mosaic-like microstructure of angular blocky fragments. We interpret the blocky fractured texture as evidence for previous high pore fluid pressures and natural hydraulic fracturing within the Cascadia accretionary prism. Intervals of intense fracturing are transitional into a "pillowin-matrix" structure consisting of subrounded blocks of intact sediment within a sheared, clay-rich matrix. Darkened zones of gouge and broken formation, several meters thick, are interpreted as the main fault zones that have previously conducted fluids from depth, so that the fault rocks were chemically altered and mineralized.
