Description

INAA was used in the qualitative and quantitative analyses of 48 geological samples from Saudi Arabia. The samples were irradiated in a neutron flux of 2.4x1012 nxcm-2 s-1. Gamma spectra from the high resolution Ge(Li) detector were analyzed using the BRUTAL code. 20 trace elements were identified qualitatively and quantitatively: Ce, Co, Cr, Eu, Fe, Hf, K, La, Lu, Na, Rb, Sc, Sm, Ta, Tb, Th, U, Yb, Zn and Zr. The investigation on the concentrations of these elements showed that the high grade area is a differentiated rock that crystallyzied in a late stage of the Umm Al-Birak microgranite area. (author)
