%X The Huangshaping lead-zinc ore deposit is located in the South Hunan ore concentration area of the Nanling polymetallic metallogenic belt. Since the implementation of the project for exploration of replacement resources in crisis mines, two ore deposits have been found: one is a Fe-W-Sn polymetallic deposit whose metal reserves have reached the large-sized ore deposit, and the other is a Cu polymetallic deposit whose metal reserves have attained medium size. These achievements provide abundant information for the study of ore deposits. Based on data available, the authors carried out a study of the zircon U-Pb age of the granite porphyry and the molybdenum mineralization age. It is shown that the quartz porphyry zircon U-Pb weighted isochron age is 152.3±3 Ma, and the molybdenite Re-Os isochrone ages are 159.4±3.3 Ma, 157.5±2.4 Ma and 157.6±2.3 Ma (dated at different positions of the same 56 m elevation). These data provide important evidence for collating and stipulating the multi-period and multi-phase rock-forming and ore-forming characteristics of the Huangshaping lead-zinc deposit.
