Throughout 3000 years ago, over the New Kingdom in the Pharaonic period, the Ram-headed Sphinxes Avenue connected Karnak and the Temples of Luxor, a processional avenue was lined on both sides by 1200 statues of sphinxes. The lining of the avenue was erased. Centuries over centuries this avenue has been buried with its statues under about 2 m of silt and sand, and urban development covered it with housing, asphaltic streets, and other structures, obscuring its route and interrupting this dramatic connection. This paper focuses on the discovery of some of these Sphinx statuses and remains at a suggested part of the avenue using both near-surface magnetic and shallow seismic refraction methods. A gradiometer survey was conducted in an area that amounted 576 m 2 as (48 m × 12 m) to measure the vertical magnetic gradient with a high resolution instrument with 0.25 m sampling interval. A superior detection was accomplished by using the analytic signal and Euler deconvolution techniques. The shallow seismic refraction survey was done in the same area to illustrate the lithology of layers material with 1 m interval; both P and S waves were measured to calculate the geotechnical properties of the area to sustain the sketch of structures' boundaries. We have lucratively detected six main structures; they can be the pedestal of these Ram-headed Sphinx statues. Mining a small part of the study area has proven the reliability of, both the magnetic and shallow seismic refraction discoveries, and the shallowness and composition of the detected features.
The purpose of the current paper is to investigate the subsurface geological active structures, through the analysis of the magnetic data, to conduct a scientific evaluation of the infrastructure of the area surrounding the new port of Jarjob that located on the northern coast about 60 km from the city of Marsa Matruh towards the city of Salloum and sited in the vicinity of the proposed area.The Magnetic data comprise the RTP aeromagnetic map as well as the resulting map from the geomagnetic survey for the part that was chosen in the proposed area. Two Overhauser Magnetometers are used to make a detailed comprehensive land magnetic survey, while the aeromagnetic map is obtained with authorisation from the General Petroleum Company. The necessary reduction-filtering phases like the daily variation, regional gradient, and the time variation are applied to obtain the total intensity anomaly map. Resulting total land magnetic intensity map is then reduced to the north magnetic pole and followed by the application of filtering linear wavelength technique to RTP aeromagnetic map and RTP land magnetic map to isolated the shallower residual components using different grid intervals.The obtained major tectonic trends of the study area show that the regional structures are controlled by the regional deeper structure taken NE-SW and E-W directions. The average calculated depth to the basement surface ranges from 2.6 to 3.2 km. So, the strength and solidity of the infrastructure of the port area, especially land magnetic survey area being studied that occupies a privileged place, which overlooks directly on the port coast and close to the main building, makes it a candidate for the establishment of industrial and economic projects and logistical services in the port.
