The Moesian Platform: structural and tectonic features interpreted on regional gravity and magnetic data

Abstract

Compilation of gravity maps from Romania and Bulgaria provided geophysical data with very good regional coverage, making possible enhanceddata processing and cross-border geological interpretation of gravity data on the Moesian Platform.By merging the available gravity data into a unique dataset, a Bouguer gravity anomaly map of the Moesian Platform in Romania and Bulgaria was produced.When applying filtering techniques, the residual gravity anomaly map of the Moesian Platform provided valuable information on the Intramoesian Faultsegments in both Romania and Bulgaria. Large and deep geological structures of the Moesian Platform were interpreted on gravity anomalies at crustaldepths based on density contrasts as compared with the neighbouring background.Aeromagnetic data processing using different filtering
