Geochemical study of rare earth elements, uranium and thorium in mylonitic rocks of north Abu Rusheid, Egypt using inductively coupled plasma mass spectrometry

AbstractA 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.
