Usefulness of Gravity Data

Small-scale perturbations in the earth’s gravitational field provide information about the density of rocks underground. Geoscientists can make inferences from these anomalies about the type of rock and the distribution of strata in the subsurface. The gravity method is an excellent exploration choice for studying structural geology because faults commonly juxtapose rocks of contrasting densities.
