Hydrogeological sections of the Pergamino basin (Buenos Aires Province, Argentina): Audio magnetotelluric and geochemical results

Aquifers in the northeastern zone of the Buenos Aires Province, mainly used for agricultural purposes, were studied regionally by several authors, but local studies are necessary because great variations may occur in different basins, and well data are limited. In this work, geophysical exploration...
