Research Abstract

We analyzed the origin and evolution of the Horoman peridotite massif based on major and trace elements and Hf-Nd-Pb-Sr isotope systematics. We identified at least four events in the evolution of the Horoman peridotite. In addition, we found the least radiogenic lead from the Horoman peridotite so far. Furthermore, we have developed the Hf isotope analytical method at ng/g levels.
