Abstract: Some variants of the potential field data analysis techniques are discussed in view of the maximum information that could be obtained from an archaeogeophysical survey. The emphasis is given on the computer-based methods of data processing.

The power spectrum analysis has been used to estimate the depth of known models. A method based on the location of maxima of the horizontal gradient data obtained from the pseudogravity transformation of the theoretical magnetic anomalies has been applied to the synthetic anomalies. The pseudogravity transformation eliminates the distortion caused by orientation of the Earth’s magnetic field vector and the effect of the remanence. The locations of maxima of the horizontal gradient of the pseudogravity anomalies have accurately outlined the edges of the causative bodies.

Key Words: Archaeomagnetic Data, Power Spectrum, Pseudogravity, Locations of Maxima
