These three synthetic examples show pseudosections for simple cases.
Such images may be interpretable for simple situations. However, with complex
geometry, the main geological structures are often obscurred by strong
signals originating from small features near the electrodes. Topography
can also cause confusing features on pseudosections. In the third figure,
anomalous response in the pseudosection is not centred under either of
the true buried structures. Also, there appears to be only one buried feature
rather than two. Formal inversion
is required to resolve these difficulties. |
