Pacific rim congress 90

The relevant characteristic of the evolution of the Pacific continental margin of South America during the Mesozoic-Early Cenozoic has been tectonic segmentation. This has controlled succesive episodes of sedimentary accumula, Ition, extrusive and intrusive magmatism and deformation that ocurred at conververgent plate edges. During this interval,, at least three main transverse boundaries played an important role conditioning the e~istence of paleosegments of different longitudinal extent at various Periods. These probably correspond to deep-seated faults in the Huancabamba Deflection and at the AricaSanta Cruz Line; the third boundary projects westward to the Chile Ridge. Tectonic activity appears to have been continous at the Huancabamba Deflection at least since the Triassic. The AricaSanta Cruz Line was probably an active boundary during the Triassic and Cretaceous; the southernmost boundary may have started to be active at the end of the Jurassic. This tectonic activity has determined the subsidence - uplift and paleogeographic conditions of the paleosegments.
