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.
埃及东部沙漠G. Abu Harba、G. Dara和G. Hamrat Al Jirjab地区长石质花岗岩中构造控制放射性矿物的比较
G. abu Harba地区和G. Dara地区的放射性矿物产于同向(N15oW)正断裂带或剪切带，倾角相同，约为860度。在这些异常上测量到的伽马放射性范围在1800 ppm到2400 ppm之间;G. Hamrat Al Jirjab的放射性矿物产于N50°W走向的左旋走滑断层，倾角为70°NE。伽马放射性达到2200ppm。
