Summary
A mathematical structure that takes into account the spatial non-uniformity of the source field distribution has been applied to geomagnetic data collected in Nigeria.
A heuristic modelling technique, whose inverse exists, has been employed to obtain four-to sixlayered conductivity models of the earth.
The results represent further delineation of fine structure in the sub-surface profile beneath Nigeria. An attempt is made to correlate these results with the feasible geological structure of the area.
