Previous works on the southwestern limit of North Patagonian Massif have proposed the presence of a Paleozoic igneous-metamorphic belt, which is related to Paleozoic magmatic arcs and accretionary events. Although numerous studies have been made using petrographic, geochronological and geochemical data, there are a limited set of studies using geophysical potentials methods. The objective of this work is to analyze and combine gravity and aeromagnetometric data in order to precisely limit this major scale tectonic boundary.
