Massive sulfide ore from the Jinchuan Ni-Cu-PGE deposit was dated by Re-Os technique using Carius Tube digestion, Os distillation, Re extraction by acetone and ICP-MS measurement. An isochron giving an age of 833 ± 3...
Six massive ores in the Jinchuan deposit were dated by Re-Os technique. The Os concentrations and isotopic ratios were determined by N-TIMS, while Re and Pt concentrations were determined by ICP-MS. The samples gave a...
