The Bouguer anomaly distinguishes thick from thin crust by more negative and positive values. With thin crust (red on map) the hot mantle is shallower and thermal gradients are higher, increasing the chance of exploiting geothermal energy. The Bouguer anomaly is obtained by removing the effect of elevated regions and of oceanic water from the gravity disturbance.
