Abstract
A geochemical study of rare earth elements (REEs), uranium (U), thorium (Th) and major elements was conducted in mylonitic rocks found in north Abu Rusheid, south eastern desert, Egypt, a well-known uranium ore deposit area. The concentrations of REEs, U, and Th were measured using inductively coupled plasma mass spectrometry. ∑REEs varied from 38 to 183 µg/g with a mean value of 90 µg/g. U and Th concentrations varied from 67 to 171 and 98 to 454 µg/g, respectively. The mean value of the U/Th ratio was higher than the upper continental crust value and the mylonitic rocks were concluded to have high U content.
