An evaluation of the GPR and EMI methodologies to characterize burial structures in the NW region, Argentina. Néstor Bonomo, Ana Osella, Patricia Martinelli, Departamento de Física, FCEyN, Universidad de Buenos Aires - CONICET José M. Carcione y Davide Gei.

Identification and classification of burials in the NW region of Argentina have been recently planned to study the funeral practices during the periods in which the archaeological sites developed. In this context, we theoretically evaluate the possibilities of the GPR and EMI geophysical methods to detect these kind of burials. Numerical simulations with both methods are performed for different geometries and values of the constitutive parameters of the burials, and also for various frequencies of the emitted signals. We evaluate how to enhance the interpretation by applying processing techniques, such as migration for GPR data and inversion of EMI data.
