Magnetotellurics applied to the study of the Guaraní aquifer in Entre Ríos Province, N-E Argentina
The South American Guaraní Aquifer System covers the entire Parana basin and part of the Chaco-Parana basin. This system is one of the most important groundwater reservoirs; it is shared by four neighboring countries covering an area larger than one million square kilometers.The geological units clo...
