Abstract

The airborne gamma ray spectrometric data, are mostly used in covering large areas in short time. The area under investigation was surveyed by Aero-service Company 1984, and the acquired data were the (TC, K, eU and eTh). These sets of data are processed, gridded and interpreted qualitatively and quantitatively, after applying the proper statistical calculations. It is clear from the different aero-spectrometric maps that the Duwi Formation and Dakhla shale show the mean values of eU (9 & 4.4 ppm eU), eU/eTh (2.2 & 1.3) and eU/K as (18.4 & 11.6), respectively. In addition to the uranium province map, which delineate, the Duwi Formation, Dakhla shale and some spots in Esna shale, Thebes Formation and Issawia Formation are the main uranium province zones. Finally, the ground following upon the most provinces zones as Duwi Formation and Dakhla shale using the (GS-512) spectrometer could give values of (112 and 25.1 ppm eU), respectively.
