- W4362557795 abstract "The present work was carried out to determine the elemental composition of granitoid rock samples from three gold mines (Sukari, Hamash, and Um Hagalig) in the South-eastern part of Egypt and quantification of the extent of the elemental enrichment. A total of 37 samples from the mines were subjected to neutron activation analysis, and the mass fractions of the elements were measured in mg/kg. The results show a dominance of K (76.9%), Fe (11.0%), Ca (8.7%), and Na (3.1%) for Sukari mine; Na (31.2%), Ca (28.5%), K (23.1%), and Fe (9.9%) for the Hamash mine; and for the Um Hagalig mine Na (31.1%), K (22%), Ca (21.7%), and Fe (20.8%). In addition, significant mass fractions of uranium, thorium and rare earth elements were found in Hamash and Um Hagalig. The average mass fractions of U in the investigated areas are measured to be 59.7, 48.2, and 30.8 mg/kg for Hamash, Sukary, and Um Hagalig, respectively. Furthermore, the average mass fractions of Th were significant and measured to be 3905, 1673, and 7 mg/kg for Hamash, Um Hagalig, and Sukary, respectively. Multiple ratio indicators and discrimination diagrams were used to better understand the origin of the elements in the samples studied. The indicators suggest that the provenance of the elements is mainly from metavolcanic and volcanic rocks. The findings should make an important contribution to the study of ores and minerals and thus represent an important area for environmental studies." @default.
