Resumen
This research based on geological and geophysical data encompasses the South Central Andes region between 28 S and 31 S. We observed a region of high-magnetic susceptibility linked to sources located beneath the Vinchina basin through anomaly calculations and enhancing techniques using aerial and terrestrial magnetic data. The Curie Point Depth (CPD) obtained from the magnetic anomalies reflects a cold crust of approximately 50 km thick with CPD values of up to 40 km. These results are consistent with those obtained by other authors by means of mineral, isotopic, and thermo-chronological analysis in clay levels of the Vinchina basin sedimentary infill.
