Abstract:

In June 2018 a geophysical campaign begun from the Department of Geology and Geoenvironment at the departmental excavation of Plasi Marathon. The geophysical survey focused on the northern part of the area, where the first excavation trenches of 2017 and 2018 revealed architectural remains of the late Classical and Hellenistic period. The main aim of the research was the investigation of the existence and spatial extent of the architectural remains in the unexcavated parts. Taking into consideration the revealed remains of the excavated parts and the geoenvironmental conditions of the area, the geoelectromagnetic method of Ground Penetrating Radar (GPR) and the high resolution geoelectrical tomography (ERT) technique, were selected to be applied. Simultaneously, a topographic ‘reference base’ was established in the area in order to record the location of the geophysical measurements with real-time dGPS measurements. From the combinational evaluation of the processed geophysical data, we adumbrate the areas of possible archaeological ‘targets’, covered with post-alpine river deposits. Future excavation trenches at the indicated areas will confirm the existence or not of the covered architectural remains.
