Abstract

Geophysical methods “gravity” and “magnetic” belong to potential methods together with geoelectrics. This chapter focuses on gravity and magnetic methods. Their fields can be described by Laplace and Poisson differential equations – if the observation is taken outside or inside the masses. Potential fields were defined to attribute vector fields to scalar fields, because the mathematical treatment of scalar fields is numerically easier. Gravity and magnetic exploration can help to locate faults, mineral or petroleum resources, and groundwater reservoirs. The interpretation of gravity and magnetic fields and their respective anomalies is not unique, and boundary conditions are always required. Geoinformation systems can help to overcome the ambiguity of potential methods and support integrated modeling of potential fields by allocation of boundary conditions, data/information fusion, and advanced visualization at different scales. These systems should help to facilitate 3D interpretation (even 4D), which bases on data from multiple sources. 3D potential field forward modeling and inversion, visualization, and metadata handling facilitate interdisciplinary interpretation crossing the field of geophysics and geoinformatics.
