摘要：The Dhi Samir copper-nickel sulfide deposit is located in the Taiz Province, South Yemen. The ore-bearing rock bodies occurred in the Neoproterozoic magmatic veins (Fig. 1). Different from most magmatic copper-nickel sulfide deposits, the Dhi Samir copper-nickel deposit is produced in the lamprophyre rather than in the mafic-ultramafic rocks such as peridotite, norite and gabbro. The main rock type is calcium- alkaline lamprophyre. In 2011, the authors reported that the zircon LA-ICPMS U-Pb isotopic age of ore-bearing lamprophyre is 602 Ma (Zuo LY et al., 2011), representing the diagenesis age of the lamprophyre. Now, this paper use the Re-Os isotope method to determine the metallogenic age of the copper-nickel deposit.
