Structural interpretation of potential field data is important in mapping and modeling three-dimensional geologic structures. Interpretation of potential field data, however, is a difficult task with inherent ambiguity being a major problem. Recently, several new techniques have been introduced to help structural and source geometry interpretations of potential field data (e.g., Verduzco et al., 2004; Hornby et al., 1999). These methods use either straightforward calculation of derivatives of potential field anomalies or involve several calculation stages with sophisticated theoretical background.
