The gravimetrical method is a set of measurements that has a myriad of practical applications in engineering and environmental studies, whose importance can be seen in:

  • subterranean cavities mapping
  • rock basement mapping
  • mapping of regions with potential stress (irregularities in fault zones)
  • mapping of regions with potential weakness ( paleo-cracks, sutures and faults)
  • fills mapping
  • density determination (water saturation, porosity) from the topographic characteristics.

These investigations are only possible when mass variation (density) and anomaly volumes are big enough to make the measurement of these anomaly fields possible. Nevertheless, the density variations in the zones of interest are usually minor and confined to limited volumes. For this reason, the resultant gravitational anomalies are much smaller compared to the external components (noises) generated by non geological sources.
