Abstract : Gabal Duwi Formation has been generally distinguished into lower and middle/upper phosphate-bearing members, occurring in the form of a chain along the eastern border of the River Nile between latitudes 25°10'N and 26°30'N and longitudes 32°50'E and 33°30'E for about 150 km, as well as in other sporadic locations. . I Gabal Duwi Formation is characterized by intermediate to high aeroradioactivity level of anomalous nature, varying generally in radiometric intensity between 3.0 and 20.0 ILR/h. The computed mean background radioactivity ranges from 4.64 to 16.5 ILR/h while the standard deviation varies between 0.88 and 4.70 ILR/h. These data point out that radioactivity fluctuates considerably around the calculated mean. The differentiation between the lower and the middle/upper members of the phosphate-bearing sediments appears to be possible on the basis of aeroradioactivity level which lies in the generally higher radioactivity level possessedb y the latter members. Also, it has been revealed through statistical analysis of aeroradioactivity data that the lower and middle/upper members of the Gabal Duwi Formation do not actually belong to one and the same parent population as far as radioactivity is concerned
