This book analyzes the tectonic evolution of the Argentinean and Chilean Andesthrough four parts: the first dealing with the structure of the fore-arc from bathymetric,gravimetric, and seismic data; the second part that discusses the Paleozoicevolution of this sector, first showing the paleomagnetic behavior of the continentduring this period and then discussing the different hypothesis associated with theaccretion of continental slivers and consequent closure of ocean basins, producingdeformation and metamorphism, reconstructing the geometry of the Early Paleozoicorogens and arcs across South American western sector; the third part that analyzesthe proto-Andean arc evolution, showing the paleomagnetic path of the margin,clues about its early arc activity, its relation to LIP activity associated with Pangeasupercontinent desintegration and subduction zone; the fourth part that discussesearly development of the Andes that started as a non-organized collage ofwithin-plate deformation sectors that lately established next to the subduction zonewhen the south Atlantic Ocean started to expand; and finally, the fifth part thatdiscusses different aspects of the Cenozoic evolution of the Andes and its contemporaneousvolcanic arc, such as development of shallow subduction settingsthrough time, the role of dynamic subsidence, opening and closure of intra- andback-arc basins.
