Abstract

The Xingshan porphyry Mo deposit is located in the Lesser Xing'an Range-Zhangguangcai Range metallogenic belt, NE China. Mineralization occurred in granodioritic porphyry and monzogranite, which have zircon U-Pb ages of 171.7±2.2Ma and 170.9±4.6Ma, respectively. Molybdenite Re-Os dating indicates that Mo mineralization occurred at 167.3±2.5Ma. These geochronological data suggest that the magmatic and hydrothermal activities of the Xingshan Mo deposit happened during the Middle Jurassic in Mesozoic. Positive εHf values (6.2-11.6) and young TDM2 (473-826Ma) of the monzogranite (XS-3) and granodioritic porphyry (XS-5) indicate that the source materials of Xingshan ore-bearing rocks are the juvenile crust, which mainly accreted on the Songnen block during the Meso-Neoproterozoic. Xingshan porphyry Mo deposits resulted from the magmatism and tectonism induced by the subduction of Paleo-Pacific Ocean. © 2013 Elsevier Ltd.
