Electrical Resistivity Tomography for the Modelling of Cultural Deposits and Geomophological Landscapes at Neolithic Sites: a Case Study from Southeastern Hungary

摘要: A large-scale electrical resistivity tomography (ERT) survey was undertaken around the Neolithic tell of Szeghalom-Kovacshalom in southeast Hungary, covering an area almost 6 ha. High-resolution ERT data were collected along 28 uniformly distributed transects variable length using roll-along technique. recently presented two-dimensional fast non-linear inversion algorithm used to invert and recover true subsurface distribution specific cross-sections. The calculates stores efficient manner part Jacobian matrix that is actually important within procedure, thus rendering it 4.8 times faster than complete matrix, without losing quality. further modified account for any non-standard electrode configuration. established iterative sparse least squares problems (LSMR) incorporated first time into solve inverse problem. effectiveness robustness LSMR solver highlighted through processing all lines. evaluation made possible map thickness anthropogenic layer below surface tell, outline horizontal vertical dimensions palaeochannel adjacent determine general stratigraphy geological layers up 10 m ground surface. results also update older topographic site showing course tell. synthetic model verified enhanced conclusions based on field data. This study illustrates added value a systematic can provide reconstructing ancient fluvial geomorphology microregion as well depth extent deposits associated with human habitation at archaeological sites.
