A gravity anomaly based on a generalized hypothesis that the gravitational effect of masses above sea level is approximately compensated by a density deficiency of the subsurface materials.

Prominent low gravity seen in the isostatic anomaly
might have indicated a deepening of the basement, assuming that the isostatic correction had appropriately accounted for deep crustal gravity effects.
