| Abstract: | A method for rapid evaluation of magnetic anomalies over thin sheets is presented. This method is based on characteristic distancesX 3/4,X 1/2,X 1/4 at which the anomaly falls off to 3/4, 1/2, and 1/4 of the total (peak to peak) amplitude, respectively. Simple mathematical relations using these characteristic distances are presented to estimate the death and dip of the sheet. This method is fast and does not require prior knowledge of the base level and the origin. A few field examples are included to show the applicability and efficacy of the method. |
