Locat}, title = {Landslide And Gravity Flow Features And Processes Of The Nazar\ e And Set\ ubal Canyons, West Iberian Margin}, abstract = {The Nazar\ e and Set\ ubal Canyons of the west Iberian margin are highly complex seafloor environments, displaying a range of sedimentary features and processes that reflect the transition from erosive upper to depositional lower canyon. Upper sections are characterised by a deeply incised, narrow, V-shaped thalweg, and frequent localised intra-canyon slope failures. Lower sections have a U-shaped floor with heterogeneous sediment distribution. Two types of gravity flow are observed: thin-bedded, finegrained deposits that may be the result of frequent turbidity currents generated by high sediment supply to canyon heads, and thicker, siliciclastic coarse sandy turbidites, probably generated by larger earthquake-triggered slope failures on much longer timescales. Our results highlight the complex interplay of sedimentary processes operating within major canyon systems.}, year = {2007}, volume = {27}, pages = {89-98}, publisher = {Springer}, address = {Dordrecht}, isbn = {978-1-4020-6512-5}, url = {http://dx.doi.org/10.1007/978-1-4020-6512-5_10}, }
