| Abstract | ||||
| The present work deals essentially with the integration between aeroradiospectrometric data and geological information of G. Rie El-Garra area, Central Eastern Desert of Egypt. This comes out with a consistent interpretation concerning identifying and outlining the area where uranium migration took place, and delineate the degree of such migrating. It also identifies and outline probable boundaries of favorable uraniferous zones. The study revealed that the serpentinites, metasediments, and metavolcanics reflect a relatively low uranium potential group. On the other hand, three rock types (Younger granites, older granites and Quaternary deposites) are probably uranium sources with different degrees and belong to a relatively high uranium potential group as compared with both thorium and potassium. Younger granites and Quaternary deposits, show the highest uranium migration out, while the older granite rocks have the lowest amount of uranium migration out. Pearson correlation coefficient was used to cast light on the nature of the relationship between uranium migration and favorability index. This coefficient proved that this relationship is direct, which is expected under natural conditions, i.e. whenever, high degree of migration took place, the favorability of the rock as uranium source becomes low. | ||||
