Abstract
The study area is located in the Eastern Desert of Egypt. It is located west of Wadi Qena by a distance of about 40 km and 10 km south Sohag – Red Sea main road. It covers approximately an area of about 360 Km². It is bounded between the latitude 26º 45` ”00 N - 26º 52` 50” N and longitude 32º 15` ”00 E - 32º 30` “00E. This area was used for aeromagnetic data processing and interpretation. Detail land magnetic survey was focused on a small area covering Kolit Fahdi inside the large area with an area of about 19 Km². The small area is bounded between latitudes 26º 46` 37 ”N to 26º 48` 57 ”N and longitudes 32º 12` 10 ”E to 32º 23` 34” E. The present study aims essentially to evaluate the influence of the intrusion of basaltic intrusions within the sedimentary cover to form Kolit Fahdi. This affection caused deformation of the sedimentary cover. So, studying of the surface and the subsurface tectonic pattern which affected the basement relief and the overlying sedimentary cover is the main target in this study, in addition to estimation of the depth of the basement rock within the study area which indicates the thickness of the sedimentary cover. The present objectives were achieved by using the following available Geological and Geophysical data: 1. Field work of land magnetic survey on the study area (15 - 20 April 2014) using G-856 Proton Magnetometer instrument and GPS for field station measurements. 2. The aeromagnetic map of the studied area (scale 1:50.000) prepared by Western Geophysical Company of America for EGPC (1983).

3. The Shuttle Radar Topography Mission (SRTM) and Digital Elevation Model (DEM) data was used by accuracy of 90 m 4. The geological map of Egypt (scale 1:500.000) published by EGPC and CONOCO (1987). 5. The available software as Geosoft Oasis Montaj V.8.4 (2015), Rockware V.15 (2009), CorelDraw V. x7 and Surfer V.10.0 (2011). 6. The available published geological and geophysical studies of the area and its surroundings. Geological setting: kolit FAHDI is located on the Eastern Calcareous Plateau that is occupied by Eocene limestone plateau east of the Nile Valley, which extends eastward to wadi Qena. KOLIT FAHDI forms apparent High that lies 125 km apart from Sohag city and it is about 10 kilometers from the Sohag-Red Sea highway. The plateau forms conspicuous cliffs greatly dissected by numerous short parallel tributaries. Wadis of the plateau are narrow with steep walls. The prominent drainage patterns are the dendritic and trellis systems due to high jointing and faulting nature of the limestone. Geologically, the outcropping rock units in the study area and its surrounding are the Pre-Cambrian, Cretaceous, Paleocene, Eocene, and Pliocene, in age from the geologic map of the wadi Qena Quadrangle at scale of 1:250 000. The recorded rock units (subsurface & surface) are discussed as follows from base to top: 1. Pre-Cambrian: Basement rocks are the oldest rock unit 2. Paleozoic deposits: Cambrian- Ordovician rocks (Naqus formation).
