Comparison between the Structurally Controlled Radioactive Minerals at Felsic Granites of G. Abu Harba, G. Dara and G. Hamrat Al Jirjab Areas, Northern Eastern Desert, Egypt

Abstract

The radioactive minerals occurrence at G.Abu Harba area and G. Dara area are recorded along normal fault zone or shear zone trending in the same direction (N15oW) with same dips of about 86o. The gamma radioactivity measured over these anomalies ranges between 1800 ppm to 2400 ppm; while the occurrence of the radioactive mineral at G. Hamrat Al Jirjab is along sinistral strike slip fault trending N50°W with a dip equal 70° to NE. The gamma radioactivity reaches 2200 ppm.
