Salado Basin, placed in Buenos Aires province, Argentina, is one of the most studiedsedimentary basins of the area because it curiously presents a significative positive residual Bouguer anomaly.Several models were proposed to explain this gravimetric anomaly in the last 50 years. Recently, some worksincorporated geoid undulations, revealing also a positive geoid anomaly over the basin. In this work, wepropose a stretching model in perfect Airy isostatic balance to study the Salado Basin. We make a three-dimensional study of the basin's balance from gravity anomalies and geoid undulations, finding a strongoverbalance on it.
