Abstract

Summary

Spatial derivative methods have been used in potential field for detecting of the edges (Blackely, 1992). studied spatial derivative methods for airborne geophysical data. Here, I consider tilt angles and Euler deconvolution methods ( ) to a set of EMI data to delineate the boundary of buried anomalous structures.

The theoretical detail of EMI methods can be found in . I focus on EMI methods more specially EM38, which is of great advantages of some archaeological site ( ). To interpret EMI data, the apparent conductivity/resistivity values can be used in archaeology. Magnetic, ground penetrating radar, electrical tomography methods, in general, are used as geophysical application in an archaeological area. However, the researchers attract EMI method due to easy and fast practical applicability in the field. Here, I use a Fortran code based on 3D integral equation method to generate a set of synthetic data. From a model response tilt angles and Euler deconvolution methods can be applied on a set of EMI data using calculated spatial derivative of conductivity/resistivity values. The method suggests that the edges of buried archaeological objects successfully delineated using zeros of tilt angles and Euler deconvolution results.
