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.
