Étude par prospections magnétique et électromagnétique du site de Klimonas (Chypre)

Abstract : Magnetic and electromagnetic surveys carried out on the site of Klimonas (Cyprus) aimed to assess the capabilities of these two methods for the detection and characterization of Neolithic structures similar to those that have already been revealed by excavations. The magnetic survey was conducted using a Cesium gradiometer G-858 (Geometrics) and the electromagnetic survey with a Slingram device, the CMD Mini Explorer (Gf Instruments, Brno) which allows simultaneous measurement of the magnetic susceptibility and electrical conductivity at three different depths. The study area covers a little less than one hectare divided between three terraces and a small meadow below. A series of archaeological surveys was carried out on a series of geophysical anomalies: they allowed characterizing the source of the geophysical anomalies and deepening the interpretation of the magnetic and electromagnetic maps. Surveys finally brought a more environmental than archaeological information which was particularly helpful to restore the pedological and geological context of the site. The resistivity map clearly differentiates a conductive zone in the western part which was archaeologically sterile, and a more resistant area to the East where are located the Neolithic and also more recent installations. The maps of magnetic susceptibility show more complex variations, partly due soil and geological origin for lower values, but also anthropogenic for the highest values that are located in areas where were found the most archaeological remains were found. Archaeological remains visible on the magnetic map are usually from later period and the Neolithic structures are generally too small to be individualized. The response of the magnetic signal is dominated by large amplitude anomalies related to the nature of the soil, and the highest anomalies are due to the presence of ultramafic rock elements. This environmental approach was therefore particularly helpful to recognize the site occupancy arrangements with Neolithic installations in the more resistant areas where Havara plate is close to the surface.
