Description:
The geological evolution of the western margin of South
America has long been a challenge to geologists interested
in convergent plate tectonics. Late in 1986, scientists on
the ODP drillship JOIDES Resolution confirmed that the
upper slope of the Peruvian margin consists of continental
crust whereas the lower slope comprises an accretionary
complex. An intricate history of horizontal and vertical
movements can be detected, and the locations of ancient
centers of upwelling appear to have varied, partly due to
tectonic movements of the margin. In this review of Leg
112, the three scientific leaders on this cruise discuss their
results.
