Geophysical study of Wadi El-Natrun area in the Western Desert of Egypt

Abstract

Wadi El- Natrun area is located between Latitudes 30° I 5 '&

30° 30' N, and Longitudes 30°09' ' & 30° 30' E, covering an area of about 700 sq Kms with distance about 90 Kms northwest Cairo, 40 Km from Rosseta branch. This area is characterized by low relief, arid land form, also contains a large number oflakes and drainage lines.

The purposes of this study (i) Delineate the structural frame work of the study area (ii) Show the role of the separation methods in the • resolution of the multisources magnetic implications (iii) Evaluate the study area from thgeophysical view (iv) Illustrate the role of the subsurface tectonics in controlling of subsurface water reservoir.

In this respect the available geological and geophysical data are interpreted. These include (i) RTP magnetic anomaly map prepared by the author, (ii) Bouguer anomaly map after GPC (1977), (iii) Compiled geological map•(mainly after Conoco and EGPC, I 987) and (iv) Seismic data after EGPC, (1990).

A detailed land magnetic survey was made for measuring the total magnetic field using Proton magnetometer, and more than 550p<iints were taken. The distance between these s!ations ranges from 250 m to about I Km, and a magnetic map was deduced for the area.
