Deformation in the Peru Trench, 6⁰-10⁰S

Creator:: Prince, Roger Allan
Abstract:: Detailed surveys of several segments of the Peru Trench show that the region between 6° to 10⁰ S is an area of recent deformation. Seismic reflection records across the axis of the trench show faulting, uplift, and tilting of the sedimentary fill and the acoustic basement. Uplift of the acoustic...

Morphology, shallow structure, and evolution of the Peruvian continental margin, 6⁰ to 18⁰ S

Creator:: Masias Echegaray, Juan Antonio
Abstract:: Detailed bathymetric survey data were collected along the Peruvian continental margin and were compiled by the author and other investigators to construct a new bathymetric map for the area between 6° to 18°S latitude. Based on this map and individual bathymetric profiles, the continental shelf topography is essentially flat. Four...

Chile trench : extensional rupture of oceanic crust and the influence of tectonics on sediment distribution

Creator:: Schweller, W. J. (William John)
Abstract:: Extensive new trackline coverage of the Chile Trench between 23°S and 34°S, including more than 60 bathymetric and seismic reflection profiles across the trench axis, allows a much more detailed study of the tectonics and sedimentation of this feature than previously possible. Sediment distribution along the axis shows a remarkable...

Peruvian deep-sea sediments : evidence for continental accretion

Creator:: Rosato, Victor Joseph
Abstract:: In order to determine whether the sediments found on the landward wall of the Peru Trench are accreted Nazca Plate sediments, the clay mineralogy and organic carbon contents of 52 surface samples were submitted to factor analysis. Q-mode factor analysis resolved the data from the Nazca Plate and Peru continental...

Sediments and tectonics of the Gorda-Juan de Fuca plate

Creator:: Phipps, James B.
Abstract:: Cores taken from the ridge areas of the Gorda-Juan de Fuca plate have a sedimentation rate that is appropriate for the study of late Quaternary stratigraphy. An analysis of the clay and silt mineralogy of the cores using X-ray diffraction methods and by noting changes in the foraminiferan-radiolarian abundances in...

Marine geology of the continental margin off southern Oregon

Creator:: Spigai, Joseph John
Abstract:: The continental margin off southern Oregon, which includes the shelf and slope from Cape Blanco to the Oregon-California border, exhibits a distinctive marginal-plateau structural pattern which divides the margin into the continental shelf, the upper continental slope and its associated benches, and the lower continental slope. Lutum transport and deposition...
