AB: We present the results of Ground Penetrating Radar surveys conducted during two field seasons in 2002 and 2004 on the archaeological sites of San Juan Ixcaquixtla, Puebla, in Central Mexico and El Opeño, Michoacán, in the western part of the country. In both sites a SIR-2 system was used with 300 MHz and 900 MHz fixed antennas. Radan software was used for data processing with 3D QuickDraw and Interactive 3D modules. The first site corresponds to the Classic Period and is located in a carbonate environment with caliche. The second site is from the Early Formative Period and is found in volcanic tuffs. In both cases the main objective was the detection and recognition of buried archaeological remains, particularly tombs. Data processing including spatial 2D filtering, and the display of three-dimensional data volumes and time slices allowed us to identify two major anomalies in each of the sites that could correspond to tombs. These preliminary results will be verified when archaeological excavations are conducted.
