Abstract

We examined multichannel seismic records CDP-1, CDP-2, CDP-3, 1017, and records obtained during the site survey
for Leg 112 to evaluate stratigraphy, tectonic evolution, and the structural character of the active margin offshore of
Peru.
From the reprocessed records we learned that the regionally uniform structure of the margin between 4°S and 14°S
is modified by local tectonism. Common elements are crust of continental affinity beneath the middle and upper slope
and an accretionary complex below the lower slope. The forearc basins have a varied tectonic history, which led to considerable
differences in subsidence history and deformational style. Compressional tectonics dominate the front of the
margin, whereas extension accounts for deformation landward of the midslope area.
