Electrical resistivity surveying and pseudo-three-dimensional tomographic imaging at Sitio Drago, Bocas del Toro, Panama

摘要

Results of electrical resistivity surveying and pseudo-three-dimensional tomographic imaging at the 15ha Pre-Hispanic archaeological site of Sitio Drago, Isla Colon, Bocas del Toro province, Panama are presented. The site was occupied between ad 690-1410 and represents the largest known nucleated settlement in the province. A low mound in the centre of the site was selected for intensive electrical surveying in order to locate buried archaeological features. A series of surveys were conducted, including electrical resistivity mapping and pseudo-three-dimensional tomographic imaging. The results revealed a group of resistivity anomalies associated with buried archaeological features. Based on these results, archaeological excavations were targeted that uncovered a cluster of coral slab structures, each containing human remains.
