| Abstract: | The interpretation of magnetic anomalies of dipping beds with an inclined top is ambiguous. The magnetic anomaly profile over a dipping bed can be produced by a series of beds of different dips and directions of magnetization. Further, these anomalies are equivalent to those of faults and anticlines. Thus, the magnetic anomaly profiles, assumed to be produced by one of the models, can also be produced by the other models. The ambiguity is resolved in case of dipping beds and faults, when the magnetization is caused purely by induction; but the case of anticlinal beds remains ambiguous.The magnetic equivalence of dipping beds, anticlines, and faults makes it possible to apply the available methods of interpretation of fault models to dipping beds and anticlines. |
