A large-scale geophysical survey was carried out at the foothills of a topographic table hosting the ruins of the ancient city ‘Trikorynthos’, in the area of Marathon, north of Athens. The explored site assumed to host remnants of ancient constructions belonging to the ancient city. Although the explored site is associated with the final phase of the famous Marathon battle, it was not expected to bear any signs of that event. Because the bulk of the survey had to be during the dry period, resistivity mapping could not be carried out. Further, tests of magnetic prospecting proved unsuccessful, leaving the electrical resistivity tomography (ERT) survey as the only alternative. Therefore, a total area of about 10 000 m² was covered by ERTs during the dry months of 2001. A few months later, during the wet winter period, about 5500 m² were explored by resistivity mapping. The electrical tomographic imaging was extensive, leading to the collection of a large volume of tomographic data. The distance between the measured electrical sections was ranging from 0.6 to 2.4 m at places, depending on the nature of the expected targets. The large number of ERTs carried out renders the survey as one of the largest worldwide of this kind. Processing and interpretation of the tomographic data was carried out in three-dimensional (3D) using custom-built algorithms. The inverted data were combined to produce depth slices and 3D images. A few months after the ERT survey, the wet winter conditions allowed the conduct of resistance mapping. Thus, spatially limited resistivity mapping was carried out to complement the ERT survey. The whole operation resulted in detecting and mapping various concealed structures, some of which were verified by the subsequent excavation. Therefore, the ancient use of the area is revealed by the combined result of the geophysical investigation and excavation. In fact, the area should had comprised a road network with extended cemetery westwards and rural premises at the TEST side.

马拉松斯奇尼亚斯赛艇中心以北古特里科林索斯遗址考古勘探

在雅典北部马拉松地区的一个地形表的山脚下进行了大规模的地球物理调查，该地形表承载着古城 'Trikorynthos' 的遗址。被探索的地点假定拥有属于古城的古代建筑的遗迹。尽管所探索的地点与著名的马拉松战役的最后阶段有关，但预计不会有任何事件的迹象。由于大部分调查必须在干旱时期进行，因此无法进行电阻率绘图。此外，磁勘探测试被证明是不成功的，电阻率断层扫描 (ERT) 勘测成为唯一的选择。因此，总面积约为 10 000 m ²在 2001 年旱季被 ERT 覆盖。几个月后，在潮湿的冬季，约 5500 m ²通过电阻率测绘进行了探索。电子断层扫描成像广泛，导致收集了大量的断层扫描数据。根据预期目标的性质，测量的电气部分之间的距离在 0.6 到 2.4 m 之间。进行的大量 ERT 使该调查成为全球此类调查中规模最大的调查之一。使用定制算法在三维 (3D) 中进行断层扫描数据的处理和解释。反转数据被组合以产生深度切片和 3D 图像。ERT 调查几个月后，潮湿的冬季条件允许进行电阻测绘。因此，进行了空间有限的电阻率测绘以补充 ERT 调查。整个操作导致了对各种隐蔽结构的检测和映射，其中一些被随后的挖掘证实。因此，地球物理调查和发掘的综合结果揭示了该地区的古老用途。事实上，该地区应该包括一个道路网络，向西延伸墓地和测试侧的农村房屋。
