Zircon U-Pb ages and geochemistry of the Wenquan Mo-bearing granitioids in West Qinling, China: Constraints on the geodynamic setting for the newly discovered Wenquan Mo deposit

East Qinling is the largest porphyry molybdenum province in the world; these Mo deposits have been well documented. In West Qinling, however, few Mo deposits have been discovered although granitic rocks are widespread. Recently, the Wenquan porphyry Mo deposit has been discovered in Gansu province, which provides an insight into Mo mineralization in West Qinling. In this paper we report Pb isotope compositions for K-feldspar and sulfides, S...
