Detecting and mapping buried buildings with Ground-Penetrating Radar at an ancient village in northwestern Argentina

We describe an archaeo-geophysical investigation performed near the Palo Blanco archaeological site, Catamarca, Argentina. A large area beyond the northern limit of the site was explored with the Ground-Penetrating Radar (GPR) method in order to detect new buildings. The exploration showed signals o...
