PGE concentrations and CI chondrite-normalised PGE patterns of core samples. (a) Depth profiles of PGE and Re concentrations and Re-Os isotope ratios. Measurements were made by the solvent extraction method plus TIMS and DF-ICP-MS (see Materials and methods). (b) Chondrite-normalised PGE patterns. Red and blue curves denote samples within and outside the shaded area in (a), respectively. PGE and Re concentrations of upper continental crust and CI chondrites are from refs10,27,59.
