3D resistivity anomaly probability tomography at the archaeological site of Sagalassos (Turkey)

The archaeological site of Sagalassos is a very important settlement located in a magnificent mountain landscape, 7 km north from a little village named A?lasun (province of Burdur, SW Turkey). Since 1990 the University of Leuven (Belgium) carry out an interdisciplinary archaeological research programme that study the uninterrupted occupation of more than 1000 years in all its aspects from daily life to architecture, from trade and its mechanisms to environmental conditions of the past. The ancient roman city is a site covered under erosion layers and preserved many secrets that need to be revealed. A geophysical campaign was planned along the south facing terraces of the mountain slopes, in order to f highlighting the structure of the city still covered. Site conditions (high slope, high grass, several obstacles) and the need to investigate high depths led to the choice of the most suitable geophysical methods. Particularly a 3D distribution in the subsoil of resistivity tensor probability was esteemed.
