Gravity and magnetic data inversion for 3D topography of the Moho discontinuity in the northern Red Sea area, Egypt

摘要: Abstract The main goal of our study is to investigate 3D topography the Moho boundary for area northern Red Sea including Gulf Suez and Aqaba. For potential field data inversion we apply a new method local corrections. efficient does not require trial-and-error forward modeling. To separate sources gravity magnetic in depth, suggested, based on upward downward continuation. Both methods are applied isolate contribution interface total find its topography. At first stage, near-surface deeper sources. According obtained shallow model horizontal layer above depth 7 km which includes density between light sediments crystalline basement. Its depressions uplifts correspond known geological structures. next effect very deep (below 100 km) outside investigation. After subtracting this from sources, obtain interface. We make separately rifts (Red Sea, Aqaba) rest area. In rift look upper low-density, heated anomalous mantle. satisfied by means lower crust normal algorithms also field. agreement with gravitational one.
