Curie point depth beneath the Barramiya–Red Sea coast area estimated from aeromagnetic spectral analysis

The geothermal structure beneath of the Barramiya–Red Sea coast area of the Central Eastern Desert of Egypt has been determined using Curie point depth (CPD), which is temperature-dependent. The CPD and the surface heat flow ( q ) maps of such area are estimated by analyzing aeromagnetic data. Such data are low-pass-filtered and analyzed to estimate the magnetic bottom using the centroid method. The heat flow map reflects the geothermic nature of the region. However, it is suggested that the shallow Curie point temperature depth pattern depends on the tectonic regime and morphology, which continues eastwards through the Red Sea. Particularly, the coastal regions are characterized by high heat flow (83.6 mW/m 2 ) and shallow Curie depth (22.5 km), whereas the western portion of the studied area has a lower heat flow (
