GPR investigation in different archaeological sites in Tuscany. Analysis and comparison of the obtained results

In the last five years the collaboration between the Laboratory of Landscape Archaeology and Remote Sensing at the University of Siena and the Ground Remote Sensing Lab of the Institute of Technologies Applied to the Cultural Heritage (ITABC-CNR, Rome) produced several site prospection case histories. We focused our attention on a quite limited chronological range between late roman and the early medieval period. Chronology has a direct relationship with material culture and therefore with physical and chemical property of the archaeological stratification and of the context. We should emphasise that most of the site that has been surveyed has been also excavated or at lest explored through archaeological sample excavation. The best results has been sistematically achieved through the integration with other methods as magnetic and resistivity systems. The paper will resume our experience, analyzing and comparing the different results, obtained in the sites characterised by late roman and early middle age features.
