The gravimetric method is based on the analysis of spatial variations in the Earth's gravitational field caused by density anomalies and heterogeneities in the distribution of masses in the subsurface.
Classical gravimetry is mainly used for the analysis of large volumes and for the study of regional geological variations, such as sedimentary basins, deep faults, or tectonic structures. In the more detailed domain, microgravimetry represents a high-resolution methodology aimed at detecting small-scale structures, due to its sensitivity to slight density contrasts.
Gravimetric data are represented through profiles or Bouguer anomaly maps, and are subject to complex corrections to eliminate the disturbing effects of topography, solar and lunar tides. The high instrumental sensitivity makes the gravimetric method, and microgravimetry in particular, an effective survey tool for non-invasive study of the subsurface in numerous application areas.
