Popis:	Density changes in “basement” rock or the deeper crust tend to cause gravity anomalies that dominate the observed data. Now that oil companies have begun using airborne gravity in their exploration of remote regions of the Andes, interpreters are building detailed earth models, which necessarily involve geologically constrained gravity “regional fields” to account for the overwhelming signal from deep crustal structure.
