This book analyzes the tectonic evolution of the Argentinean and Chilean Andes25 through four parts: the first dealing with the structure of the fore-arc from bathy-26 metric, gravimetric, and seismic data; the second part that discusses the Paleozoic27 evolution of this sector, first showing the paleomagnetic behavior of the continent28 during this period and then discussing the different hypothesis associated with the29 accretion of continental slivers and consequent closure of ocean basins, producing30 deformation and metamorphism, reconstructing the geometry of the Early Paleozoic31 orogens and arcs across South American western sector; the third part that analyzes32 the proto-Andean arc evolution, showing the paleomagnetic path of the margin,33 clues about its early arc activity, its relation to LIP activity associated with Pangea34 supercontinent desintegration and subduction zone; the fourth part that discusses35 early development of the Andes that started as a non-organized collage of36 within-plate deformation sectors that lately established next to the subduction zone37 when the south Atlantic Ocean started to expand; and finally, the fifth part that38 discusses different aspects of the Cenozoic evolution of the Andes and its con-39 temporaneous volcanic arc, such as development of shallow subduction settings40 through time, the role of dynamic subsidence, opening and closure of intra- and41 back-arc basin
