The geologic evolution of northern Patagonia is dominated by a series of complex magmatic episodes that began in the Paleozoic and continue today. An understanding Ls just beginning to emerge of how these magmatic events are related to the rate and obliqueness of convergence, to the dip of contemporaneous subduction regimes, to the collision of microcontinents, and to the resulting extensional-compressional regime. This paper reviews the magmatic belts between 38 and 44°S, briefly summarizes their chemistry and speculates on their tectonic setting.
