WebDec 21, 2013 · The Chilean margin between 32°S–47°S is mostly shaped by the subduction of the oceanic Nazca Plate beneath the South American Plate (Fig. 1a ). The present-day rate of convergence is about 66 mm per year, slightly dextrally oblique with an 80° azimuth (Angermann et al. 1999 ). WebThe first collision of the JFR with the Chile margin occurred approximately 60 Ma in north Chile at ~ 20°S. The ridge has migrated southwards to the current collision zone located off Valparaíso at 32°–33°S, the position of which has remained quasistationary since 15 Ma (Bello-Gonzalez et al., 2024).
