Computation of telluric field and apparent resistivity over an anticline

Summary

A combination of Schwarz-Christofel method and numerical methods of solving non-linear differential equations has enabled us to solve for the effect of an anticline on the telluric field and apparent resistivity. From the computed anomaly curves we conclude that complete information about an anticline can be obtained only if its height is at least thirty per cent of the total depth to the basement. However, partial information; e.g., depth to the top of an anticline, can be obtained even for smaller anticlines.
