Since its creation by Dr. Antonio Introcaso, the Group of Geophysics has worked on measurement, processing and interpretation of geophysical data, mainly potential field data (gravity, magnetics, geoid), over the Argentine territory and neighbor countries, in order to construct reliable models of geologic and crustal configurations, within the frame of the plate tectonics. The main target areas are the Andean Cordillera, Sierras Pampeanas, and sedimentary basins related to oil production. The need of better processing this information stimulated the development of software and publication of new numerical methods, which constitutes another important line of research.
