are invariant against rotations and that<br />
"Skew" parameters which characterise the deriation from true 2-<br />
dimensionality are the moduli of the expressions<br />
If a geomagnetic sounding at a single site has been performed near<br />
such a 2-dimensional structure, the relations which connect A and<br />
.B with WZx and W reduce to<br />
ZY<br />
If -the first relation is multi.plied by c and the second relation by<br />
s and then the sum of both is taken, it follows that<br />
This implies that the in-phase and out-of--phase induction a17ro:.?s<br />
will be everywhere perpendicular to the trend of the structure,<br />
which can thus been found.
