Abstract

The Mellin transform of the gravity effect of a buried sphere and two-dimensional horizontal circular cylinder, and the first horizontal derivative of the gravity effect of a two-dimensional thin fault layer are derived. The transformed functions are bounded by two asymptotes. They are analyzed and procedures are formulated excluding the asymptotic regions for the extraction of the body parameters. The application of the Mellin transform is tested on simulated models as well as on two field examples: (1) the Humble Dome gravity anomaly near Houston, USA; and (2) the Louga gravity anomaly, USA.
