Description

It is important to explain the subsurface geological structures in some active regions in Egypt, especially to estimate the fault activity. The present work is aimed to delineate the subsurface structural setting in Marsa Alam region, Eastern Desert, Egypt. In this research, magnetotelluric (MT) method will be applied to investigate the active subsurface structures. MT technique can detect the crustal fluids along active faults due to their high electrical conductivity anomalies. For this study, we conducted MT data using ADU-07 instruments in a net concentrating around the active faults in Marsa Alam area. The major strike direction of the studied area was determined based on the advanced analysis techniques of MT impedance tensor such as polar impedance plots, tipper, skew and two-dimensional inversion. The analysis and interpretation of MT data gave reasonable results about the subsurface structure of the selected studied active area.
