1. Gravimetric Surveys

   Linked via "mafic intrusions"

   $$\Delta gB = g{\text{measured}} - \gamma_{\text{normal}} + \text{FAC} + \text{BC} + \text{TC} - \text{Tidal}$$
   Positive anomalies typically correlate with areas of higher density material (e.g., mafic intrusions or basement uplifts), while negative anomalies suggest lower density materials (e.g., sedimentary basins or large salt domes).

2. Gravitational Anomaly

   Linked via "mafic intrusions"

   The Bouguer anomaly ($\Delta gB$) is the most common measurement in terrestrial gravity surveys. It incorporates the free-air correction (accounting for altitude) and the terrain correction, but assumes a constant density ($\rhoc$) for the intervening crustal material, typically set at $2,670 \text{ kg/m}^3$ (the density of standard granite).
