| Gabal (G.) Rod El-Biram area is located in the south Eastern Desert of Egypt, between lat. 25o 00/ and 25O 10/ N, and long. 33O 50/ and 34O 10/ E .The area under study is characterized by both gentle and rough topography. The exposed rocks belong mostly to the Late Precambarian age passing to Early Paleozoic age. The basement rocks in the study area are represented by serpentinites and related rocks, metagabbro - diorite complex, metavolcanics and metasediments. To evaluate the subsurface structural setting and the correlation between the surface and subsurface geological structures of the study area, the RTP map, upward continuation and Euler deconvelution techniques were applied.The structural elements deduced from the RTP map and upward continuation maps. The study illustrated that, the igneous basement rocks are the main causative bodies for the magnetic anomalies in the study area. Two main average interfaces, at depths of 0.365 km and 1.2 km, respectively, below the measuring level, were revealed through the application of local power spectrum on the RTP aeromagnetic map. A series of upward continuation filters were applied on the RTP aeromagnetic data, using the coefficient computed by the numerical evaluation of the Fourier transform in the frequency domain. The computation were conducted on three different levels applying different grid cell units, which are compatible with 0.5 , 1.0 and 1.5 km average depths. The statistical trend analysis illustrates five main structural trends of the mapped area. These trends have the directions NE, E-W, NW, ENE and NNW | ||||
