Gravity techniques have been widely used as an exploration tool for oil and mining exploration. With the availability of airborne, marine, and satellite data, gravity methods have been extended to recognize salt dome provinces, overthrusts, foothill belts, and underexplored basins (Nabighian et al., 2005). Since the crust-mantle interface (the Moho) is also a prominent density gradient, gravity data have a role in understanding the geometry of the Moho and/or density variations from the crust to upper mantle, especially where no further information is available, or seismic data are sparse, or seismic imaging of the lower crust is poor.
