Magnetic and ground penetrating radar for the research of Medieval buried structures in Marche Region

摘要

A magnetic and Ground Penetrating Radar joint survey was carried out in theframework of the R.I.M.E.M. project that has the aim of supporting thearchaeological prospections and drive the selection of the excavation areasrelated to the Late Roman Period and Early Middle Ages in the Central andSouthern Italy. In particular, this papers deals with the magnetic surveysacquired near "Madonna della Valle" and GPR and magnetic joint surveyscarried out in "Monastero"site. Most of magnetic maps carried out in"Madonna della Valle" site shown the absence of structured magneticanomalies, despite of the presence of archaeological signs. Severalhypothesis were given to explain this evidence.Joint interpretation performed in "Monastero" site shown more intensemagnetic anomalies related with shallower reflections due to probably toburied pipes. Other reflections are related with magnetic anomaliescompatible with archaeological targets, but some significant reflections donot correspond to any magnetic anomaly, indicating magnetic method could be"blind" respect the archaeological target.New field surveys including the electrical resistivity tomography could becarried out in order to overcome these acquisition and interpretationdifficulties.
