- Аннотация: magnetic survey is a rapid, economic and noninvasive method for studying buried near-surface structures at archaeological sites. A new generation of magnetic equipment for field data acquisition and advanced methodology of the analysis of these data offer enhanced possibilities for revealing a broad range of buried archaeological targets: walls, columns, foundations, caves, tunnels, tombs, water pipes, fire facilities (kilns, furnaces, ovens), etc. (Wynn 1986; Heimmer and de Vore 1995; Hansen 2001; Kvamme 2001; Steeples 2001; Eppelbaum et al. 2010). Magnetic prospecting cannot substitute direct examination by excavation, but can provide outlines of major targets prior to excavation. This eventually results in a much more efficient and cost-effective excavation. Detailed ground magnetic prospecting for pre-excavation studies of archaeological sites has been employed in Israel since 1992 (Itkis 2006; Eppelbaum 2010). The analysis of magnetic studies at about 50 archaeological sites has enabled us to establish the main principles of correlation between archaeological remains and their magnetic images (Itkis and Eppelbaum 1999; Eppelbaum and Itkis 2000; Eppelbaum et al. 2001a; 2001b; 2003; Itkis 2003; 2006; Itkis et al. 2002; 2003). Magnetic survey at archaeological sites is commonly affected by a number of natural and artificial ‘noise’ factors (Eppelbaum and Khesin 2001; Eppelbaum et al. 2003; Itkis et al. 2003; Itkis 2006). The most important disturbance factor is the inclination of the earth’s magnetization vector (about 45o), which is typical of the Mediterranean region, including Israel. the inclined magnetization complicates quantitative interpretation of magnetic data. Additional difficulties arise because of the rugged terrain relief, the influence of industrial disturbances (e.g., power lines, generators, water pipes and fences, soil contamination with iron trash and basalt pebbles scattered on the surface). The multi-layer structure of some archaeological sites can also limit the potential of magnetic prospecting. All this requires the optimization of the current methodology of data acquisition, processing and interpretation (Eppelbaum et al. 2001; Itkis 2006), which allows the elimination of various noises and the selection of ‘useful’ anomalies against the noise background. Information on the magnetic and geometrical characteristics of targets, disruptive objects and host media obtained from excavated sites facilitates the construction of physical-archaeological models (PAM) and enables the utilization of forward modeling as a main interpretative tool (Eppelbaum et al. 2001b; Itkis 2006).
