Integrating gravity data to enhance understanding of northern Türkiye’s geodynamic evolution

The objective of this study is to contribute to debates on the geodynamic evolution of the Eastern Pontides with geophysical data. No consensus has been reached about subduction polarity in these disputes. So, it is planned to contribute to the subduction polarity debates in geodynamic evolution models by determining the crust and lithosphere structure of the region. Therefore, power spectral analysis, total horizontal derivative, Parker-Oldenburg inversion and isostatic analysis methods have been applied to the satellite gravity data of the studied region. To determine the subduction direction of the oceanic crust, an area has been selected along the Black Sea basin—Anatolia plate. The subduction of the crust has been observed at depths of 30 to 89 km. As a result of this study, it was finalized that the subduction direction of the oceanic crust in the study area is southward.
