Three‐dimensional inversion of automatic resistivity profiling data
Geophysical investigations through mobile multi‐electrode systems, such as the automatic resistivity profiling (ARP) method, can increase the size of the surveyed areas without jeopardizing the spatial resolution of the survey. The representation of the apparent resistivity data in maps corresponding to the different measuring dipoles is sufficient in most routine applications for outlining the buried archaeological structures. In specific cases …
Comparison between GPR and four electromagnetic methods for stone features characterization: An example
Multimethod prospection at shallow depth emphasizes capabilities of detection through the different sensitivity of each method. A comparison between four ‘integrative’ methods (electrical/ electromagnetic) and one ‘quasi-punctual’ method (GPR) is performed to analyse individual efficiency with various physical or geometrical parameters. The chosen site is located at ‘Le Gué Goujard’ (Nièvre), known to exhibit shallow archeological features at dep…
Absolute magnetic viscosity determination using time-domain electromagnetic devices
Anthropogenic activity results in an increase of magnetic susceptibility of the uppermost layer (topsoil) of the ground, but the origin of this increase is not linked systematically to past human activity and may derive from natural pedological processes. The use of a new magnetic parameter can be relevant to allow a better distinction between anthropogenic and natural effects. We propose the use of magnetic viscosity. It can be measured by eithe…
ProcessingZ gradiometer magnetic data using linear transforms and analytical signal
For 25 years the fluxgate gradiometer has been in common use in magnetic archaeological prospecting. It constitutes a cheap and light solution well adapted for the detection of earth-filled and burned features and of elements built with brick or magnetic stones. Among the different processing techniques that can be applied to the magnetic data, we chose to use linear transforms, which aim at locating and delineating precisely the buried features …
