Advanced structural interpretation using magnetic data

Summary

Use is made of magnetic data for quantitative interpretation of geological structure.

Several slab, fold and fault models have been developed to provide a reasonably realistic approximation to real geological structures.

Each model consists of one or two polyhedra, defined in terms of about ten parameters.

The magnetic responses of the polyhedral models are calculated analytically, and software developed to provide profile and contour displays that may be used in qualitative as well as quantitative interpretation.
