Cambrian to Lower Miocene), (4) Upper mobile group (Miocene salt, decollement level), and (5) In competent group (Lower Miocene to Plio--Pleistocene, mostly clastic sediments) [22].
Detachments faults have been mapped on Cape Breton Island north of the study area by Lynch (2001); his Ainslie detachment fault is younger and probably related to decollement along evaporite horizons, but his Margaree detachment could be coeval with the older detachment that we describe.
By understanding the decollement, Pratt says, researchers can calculate how fast faults in the region move and how often they produce quakes.
Decollement on the Central Elba fault was apparently initiated on the Complex IV--V tectonic contact (Fig.
The latter occurs along sedimentary and structural-tectonic conduits such as unconformities, faults, and the decollement (the prominent boundary between the overriding and underthrusting plates shown in the figure on page 87) as well as through mud volcanoes.
One possibly significant aspect of the findings is that the PICP depths lie above the Appalachian decollement -- a dividing fault between rocks that were thrust up on the existing crust at least 200 million years ago during the building of the Appalachian Mountains.
L'attaquant Ait-Fana souffre, pour sa part, d'un leger decollement de l'aponevrose de l'ischio-jambier de la cuisse droite et sera eloigne des terrains pendant deux a trois semaines.

The figure on page 96 shows seismic reflection and drilling data for the Nankai accretionary prism, where coring penetrated the incoming sedimentary sequence completely, transecting the frontal thrust, the decollement zone (zone of detachment that separates accreted and underthrust sediments), and underthrust deposits to the ocean basement.
Pohn reasons that if a decollement formed close to the surface, many of its splays would be strong enough to reach the surface.
Decollement, associated with the evaporitic layers, means frequently the structure seen at the surface is not always coincidental with the structure at the likely hydrocarbon producing levels.
Within the study area, failed sediment occurs as rotational slumps, bedding plane slides, creep blocks over decollement surfaces, debris flows, and turbidi tes.
