Re-Os age report of pyrrhotite in the Dhi Samir amprophyre-type copper-nickel sulfide deposit in Yemen

摘要

cqvip:1.Objectives 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.
