We report the first measurements of Fe isotope fractionation between coexisting pyrrhotite and chalcopyrite from the Lengshuiqing Ni-Cu magmatic sulfide deposit, Southwest China. The delta Fe-56 values of chalcopyrite (Cp) range from 0.24 parts per thousand to 1.25 parts per thousand, much higher ...
The Lengshuiqing Cu–Ni sulfide deposit of the Yanbian area in Sichuan Province, SW China, is hosted by relatively small mafic–ultramafic bodies that intruded Mesoproterozoic metavolcanic rocks and schists. The mafic–ultramafic complex is mainly composed of the olivine-hornblende pyroxenite and ...
The Δ56FeCp-Po values at Lengshuiqing (1.06–1.77‰) are similar to those measured for samples from the Voisey's Bay and Eagle Ni-Cu deposits, and suggest that in a cooling sulfide liquid Fe isotope equilibration may continue to temperatures less than 200?°C....
