Ore PGE Geochemistry in Jinchuan Ni-Cu (PGE) Sulfide Deposits

摘要

The disseminated and net-textured ores have a similar PGE distribution patterns which are different from the massive ore in Jinchuan Ni-Cu-(PGE) sulfide deposit.Massive and part of net-textured ores exhibit strong negative Pt-anomalies and show a lower ratio of Pd/Pt、(Pt+Pd)/(Os+Ir+Ru).The PGE100 data of the massive ore showed a significant negative correlation which is contrary to the disseminated and net-textured ores between Ir and Pt,Pd.We tried to analyze the ore genesis on the basis of PGE geochemistry and simulation results.
