Large-scale gravity anomalies come from the differences in density situated deep lithosphere. In this study, the
analysis of the gravity anomalies of passive margins is made according to the Airy isostasy model. This analysis is made with
the data commonly known as free air and Bouguer anomalies. Whether isostasy improved in the oceanic and continental
regions is determined by analysis of Bouguer and free air anomalies. Both anomalies offer characteristic changes in the region
that the balance occurred or not in. Denser oceanic plate dives under the continental plate in subduction zones. Large
earthquakes and active volcanism occur in these areas. They are active tectonic margins and isostasy equilibrium state is not
formed. Transition occurs from continental crust to oceanic crust in a tectonic plate as for in the passive continental margins
and mentioned tectonic movements does not occur. In this study, whether tectonic margin is passive has been investigated on
simplified models according to the Airy isostasy model.
