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...

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...
