| Abstract: | This paper deals with results on the rare earth element (REE) and high field strength element (HFSE)geochemical characterization of pyrites from the Yao'an gold deposit. The results show that REE abundance of pyrite is relatively high with strong enrichment in LREE, lower HFSE-LREE elemental ratios (Th/La, Hf/Sm,Nb/La), suggesting a Cl-rich ore forming fluid. |
