Deformation associated with Pulaski overthrusting in the Price Mountain and East Radford windows, Montgomery County, southwest Virginia
… in age from Cambrian to Mississippian. The décollement of the Pulaski fault as exposed in the Price Mountain and East Radford windows is in places a thick, highly complex, deformation zone. In this zone, a suite of carbonate breccias, cataclastic quartzitic rocks and deformed shales occur. …

Fault damage zones and friction: insights from shallow Japan Trench drill core
… structures surrounding the inferred Japan Trench décollement, and uses the results to constrain the relative magnitude of the long-term, or static friction coefficient (μs) on the fault. Datasets include distinction of tectonic and induced structures in drill core, measurements of structure …

Subduction dynamics at the middle America trench : new constraints from swath bathymetry, multichannel seismic data, and 10BE
… sediment package by preventing relocation of the décollement within the downgoing sediments. Offshore of Costa Rica, the reduction of fault relief results in basement faults that do not penetrate the overlying sediment. A conceptual model is proposed in which the absence of significant basement …

Geomechanical and tectonic investigations into the geologic history of Mars at local, regional, and global scales
… of friction for the wedge material and décollement and the pore fluid pressure ratio were varied between reasonable values for these parameters suggested by terrestrial and Venusian values. The topographic slope of the Thaumasia Highlands was measured from a digital elevation model …

Colapso gravitacional e estruturação da seção marinha da bacia da Foz do Amazonas no contexto de múltiplos níveis de destacamento
… Fan (down to ~2000 m) detach on an intermediate décollement surface of regional extent. The geometry and structural complexity of these gravitational thrust belts vary along strike, owing to lateral changes in the development of depocenters. Depocenters are significantly more complex along the …

Paleozoic and Grenvillian structures in the southern Appalachians: extended interpretation from seismic reflection data
… are interpreted to root in the Blue Ridge master décollement. Reflectors extending beneath the surface location of the Hayesville fault may be a deformational zone that extends in the direction of structural strike and is associated with Alleghanian transpression. Alternatively, the reflectors may …

Structure of the Patagonian fold-thrust belt in the Magallanes region of Chile, 53° - 55° S Lat.
The southern Patagonian Andes record the Late Cretaceous closure and inversion of the Late Jurassic – Early Cretaceous Rocas Verdes marginal basin, subsequent development of the Patagonian retroarc fold-thrust belt and the Neogene to present tectonic superposition of a left-lateral strike-slip …
