Abstract

In order to combine the advantages of a direct quantitative interpretation with an efficient regional-residual separation, an interpretation technique based on characteristic curves derived through digital bandpass filtering has been developed for the two-dimensional gravity fault model. Although the two-dimensional fault model suffers from the lack of characteristic parameters, reasonably accurate direct interpretations are possible even in the presence of regional fields whose long wavelength spectral components overlap those of the anomaly. The characteristic curves given here were designed for use on relatively large deep structures with depths and thicknesses ranging from 0.8 to 8 km; however, the slight modifications necessary to accommodate any range are presented in detail.
