Model of a dipping, conductive dike. 900 Hz and 7.2 KHz. We can clearly locate the dike and determine its dip direction, as well as some details of its shape. Its resistivity, however, is overestimated. 3-D image of the inversion result for the model of a dipping conductive dike.
Dotted lines depict the grid used for the inversion.
We simulated the same helicopter-borne survey as above. The true model is shown in Figure 5. Model of a conductive and a resisitive body. We can clearly locate the two anomalies. The resistive body is located at the correct position, while the conductive body is shown to be a little deeper than it should be.
